## Accounting knowledge we require

**Financial reporting & the close**

- US GAAP financial statements and the period-end close and reporting cycle
- Reconciliations, substantive analytics, and tie-outs to source documents
- Subledger-to-general-ledger tie-out, and what it means for a period to be open, locked, or reopened

**Judgment & evaluation**

- Materiality and the evaluation of errors and misstatements; when an item is or isn't material
- Adjusting journal entries and their coupled effects (e.g., deferred tax)
- Distinguishing an entry actually posted to the ledger from one sitting as a draft, an unposted batch, or a working-paper adjustment

## What you'll do

- Review AI-agent attempts at realistic accounting tasks and judge whether each conclusion is correct and adequately supported
- Confirm work is actually completed and recorded — entries booked, findings logged, deliverables filed — not just described

Accounting Expert

**Join a leading AI lab's cutting-edge GenAI team to be at the core of the AI revolution, where your expertise fuels the development of the most advanced AI models.**

## 1\. Overview

We are hiring a senior **business and sales operations domain expert** to work directly with a leading AI lab's research and program management teams, improving how frontier AI models reason about real business operations work.

Your operating expertise is the substance of this role. You will review the quality of business operations knowledge work tasks, write the instruction specs and golden solutions that define what "correct" looks like, and build the benchmarks that show whether the model is genuinely improving. We are looking for a practicing operator rather than a generalist.

This is a full-time W-2 employment position with Cincinnatus LLC, with the opportunity to be placed at a leading AI lab as part of their extended workforce. You will be provisioned with client-issued accounts and equipment, and will work inside the client's own tools alongside their research teams.

**Location:** This is a **hybrid** role based in the **Bay Area, California**. You must live in the Bay Area and work on-site with the client's team multiple days each week, when required. This is not a remote role. If you do not currently live in the Bay Area, you must be willing to relocate there at your own cost before the engagement starts. Relocation assistance is not provided.

## 2\. Key Responsibilities

- **Data QA and reviews:** Vet the quality of business and sales operations knowledge work tasks and model outputs, spotting missing behaviors, thin reasoning, flawed assumptions, numbers that do not tie, and answers that read well but would not survive an operating review.
    
- **Instruction specs and golden datasets:** Write high-quality instruction specs, produce golden solutions to operations problems, and define new tasks that reflect how the work is actually done in practice.
    
- **Benchmarks and domain depth:** Design challenging operations tasks and evaluation sets, and help build domain-specific skills and tools together with the research team.
    
- **Calibration:** Work with client researchers and specialists in adjacent fields to keep standards consistent, translating tacit operating judgment into explicit, teachable criteria.
    

## 3\. Core Qualifications

- **Experience:** 4+ years of substantive ownership of a business, revenue, or sales operations function at a recognized organization. Individual quota-carrying sales roles with no operations ownership do not count.
    
- **Seniority:** Clear progression to a senior level, for example Manager, Senior Manager, Director, Vice President, COO, or President, with real ownership of a function, a budget, or a team.
    
- **Domain depth:** Genuine specialization in at least one area, for example sales operations and territory or quota design, revenue operations and forecasting, CRM and go to market systems, pricing and deal desk, supply chain and inventory planning, business analytics, or process improvement.
    
- **Education:** A bachelor's degree, with an MBA or an equivalent advanced degree strongly preferred.
    
- **AI fluency:** Hands-on working use of large language models in your professional work, and the judgment to tell a well-reasoned answer from a plausible-sounding wrong one.
    
- **Availability:** Able to commit reliably to 40 hours per week for an initial engagement of 6 months.
    
- **Location:** Living in the Bay Area, California, and able to work on-site with the client's team multiple days each week, when required. Candidates not currently based in the Bay Area must be willing to relocate there at their own cost. Relocation assistance is not provided.
    
- Excellent written communication, and the ability to give precise, well-structured written feedback.

Engineering & Software Domain Expert

**Role Overview**

Mercor is running a short, structured evaluation pilot to measure how frontier AI models perform on realistic professional work — and how experienced practitioners judge that work. We are hiring 25 experts across four business domains. Each expert completes one task, then evaluates five model attempts at that same task. This is a one-time study, not ongoing production work.

**What You'll Do**

- Sign an NDA before receiving any materials.
    
- Solve one realistic, domain-specific task using the source files provided.
    
- Review five model-generated outputs for that task. Rank them 1–5 with no ties, score each 0–100, and write evidence-based rationales that cite specific parts of the output.
    
- Provide structured feedback on the task itself and on the study design.
    

**Time Commitment**

Up to 13 hours total: 3–10 hours to solve the task, approximately 2 hours to rank and score the five outputs, and approximately 1 hour to provide feedback.

**Study Conditions**

- No rubric and no golden answer are provided. Your professional judgment is the measurement.
    
- Use of LLMs or other AI assistants is prohibited at every stage — solving, ranking, scoring, and writing rationales.
    

**Domains we are focused on**

- Admin / Business Operations
    
- Marketing
    
- Human Resources
    
- Accounting
    

**Who We're Looking For**

- 5+ years of hands-on professional experience in one of the four domains above.
    
- Currently or recently practicing, so you can judge the work the way a working professional would.
    
- Able to write a clear, specific, evidence-grounded rationale for a judgment.
    
- Reliable within a short turnaround window.
    

**Eligibility Restriction**

You are not eligible for this pilot if you have worked on Project Alchemy in any capacity — task author, reviewer, world expert, or anyone who has had access to its source world data. Prior exposure to that material would invalidate the study.

Business Domain Expert — AI Model Evaluation Pilot (Admin, Marketing, HR, Accounting)

# Domain Expert – Diagnostic Imaging (Visage 7 Research)

To qualify you must use Visage 7 regularly — weekly or more — as a working part of your job, with 2+ years of professional experience in radiology, imaging operations, or imaging IT.

## Visage 7 knowledge we require

### Study interpretation & measurement

- Establishing a patient's current imaging position as of a given study date, and comparing it against the relevant prior — not just the most recent one
    
- Distinguishing a measurement or annotation that has been saved and persisted from one that exists only in the open session
    
- Reading multi-series, multi-timepoint studies; knowing when a finding requires additional imaging, a critical-results call, or subspecialty over-read versus a routine sign-off
    
- Quantitative work where applicable: RECIST/PERCIST timepoint tracking, SUV values and their calibration dependencies, vessel and volume measurement, fusion and registration accuracy
    

### Patient & study records

- Patient / study / series / instance hierarchy, and the identifiers that bind them — MRN, accession number, Study Instance UID, procedure code
    
- Recording interpretation and communication history accurately, including on partial, preliminary, or handed-off information
    
- Setting and interpreting follow-up recommendations, flags, and recall dates on a patient's record
    

### Worklist & reading workflow

- Worklist construction, filters, and study status transitions (scheduled, arrived, read-in-progress, dictated, preliminary, final, addended)
    
- Claiming and releasing studies; recognizing what a preliminary or wet read commits you to versus a signed final report
    
- Distinguishing what is confirmed from what is assumed when picking up a study mid-read or inheriting a shift handoff
    
- Prior fetching and relevance rules — why an expected prior is absent, and what to do about it
    

### Reference & configuration data

- Hanging protocols, display protocols, and window/level presets, and how configuration constrains what a reader can see by default
    
- Procedure code and protocol mapping, series descriptions, and how upstream acquisition labeling determines downstream display
    
- DICOM tag-level familiarity sufficient to diagnose a mis-hung, mis-labeled, or mis-routed study
    
- Cross-system references where relevant: RIS/EHR order, dictation system, AI result overlays
    

### Regulatory & clinical standards

- Applying the organization's own protocol, dose, and reporting standards to determine whether a study is complete and interpretable
    
- Version and currency awareness — which protocol, template, or criteria set applies as of the study date, not as of today
    
- Where relevant to your role: MQSA, ACR accreditation and dose registry requirements, critical-findings communication policy, information-blocking and patient-release rules
    

### Audit & handoff

- Recording findings, measurements, key images, and open items so the next reader, the ordering clinician, or a tumor board can see exactly what was concluded and what remains outstanding
    
- Persistence of annotations, presentation states, and key-image selections so a later viewer reproduces what you saw
    
- Peer review, discrepancy, and amendment workflows; audit trail and access logging
    

## What you'll do

- Confirm the patient's imaging record reflects what was actually acquired and actually concluded, not what is assumed — especially on partial handoffs and incomplete studies
    
- Work out the current imaging position as of the relevant study date, compared against the correct prior, and record it with a follow-up recommendation where indicated
    
- Distinguish session-only actions from those that persist to the record and affect downstream readers
    
- Judge completeness: is the study interpretable, is the correct prior available, is anything left open that shouldn't be, is the record ready for the next reader or for conference
    
- Verify recorded outcomes are traceable — reproducible and auditable, not just noted informally
    

## Requirements

- Frequent Visage 7 use — weekly or more — in your current or recent role
    
- 2+ years of professional experience in diagnostic radiology, imaging technology, imaging operations, or PACS/imaging informatics
    
- Reflexive familiarity with study status transitions, prior comparison, and the preliminary-versus-final distinction
    
- One of the following:
    
    - MD/DO with radiology residency or fellowship training (board certification or eligibility preferred), or
        
    - ARRT, RDMS, NMTCB, or equivalent technologist credential with hands-on advanced-visualization experience, or
        
    - Bachelor's degree in health informatics, medical imaging, computer science, or a related field, plus imaging informatics certification (CIIP, PARCA) or equivalent hands-on PACS administration experience

Domain Expert – Diagnostic Imaging (Visage 7 Research)

**About This Survey**

Mercor is opening a series of compliance and financial-crime engagements with leading AI labs over the coming weeks and months — spanning AML and BSA, KYC and client due diligence, sanctions screening, transaction monitoring and financial crime investigation, securities and wealth compliance, conduct and surveillance, regulatory reporting, and compliance testing and assurance. Before we finalize the scope of each, we want to build them around how compliance professionals _actually_ work, not how the field is described in textbooks or public sources.

This is a written intake designed to map out the real workflows, tools, decision points, and specialty cuts inside the profession — from the inside.

**What You'll Do**

- Complete a ~15 minute written intake about your compliance practice
    
- Describe your day-to-day workflows, how your time is split, and the workflows core to your role
    
- Explain how experienced practitioners actually divide the field from the inside — the cuts insiders use, not the textbook ones
    
- Tell us where AI already gets your work wrong, with concrete examples from your own casework
    
- Share the "invisible" parts of your work that outsiders (including project designers) tend to miss
    
- No right or wrong answers — detail and specificity matter far more than polish
    

**Ideal Respondents**

- Practicing or recently practicing compliance and financial-crime professionals — first line, second line, internal audit, or external advisory
    
- Any seat: KYC/CDD and client onboarding, transaction monitoring and AML investigations, sanctions and screening, fraud and disputes, trade and communications surveillance, conduct and consumer-protection compliance, regulatory reporting and change, compliance testing and assurance
    
- CAMS, CGSS, CFCS, CFE, CRCM, an ICA diploma, or FINRA registrations preferred; deep domain experience without a credential is equally welcome
    
- Willing to write detailed, specific responses about the mechanics of your work
    

**Why This Matters**

- Your intake shapes the scope of the compliance engagements we launch
    
- Thoughtful responses translate directly into **more offer matches** and priority routing as we open new engagements over the coming weeks and months
    
- Typical compliance rates on Mercor range from **$90–$110/hr** and scale with seniority

Mercor is a talent marketplace that connects experts with leading AI labs and research organizations. Backed by Benchmark, General Catalyst, Adam D'Angelo, Larry Summers, and Jack Dorsey.

Compliance & Financial Crime Domain Intake — Shape Upcoming Compliance Engagements

**Mercor is partnering with a venture-backed AI lab building frontier AI platforms and physics-based foundation models for chemistry, materials science, and drug discovery.** They're extending their platform into new areas of pharmaceutical development and are looking for hands-on preclinical R&D experts across drug modalities to help guide what they build.

Are you a preclinical R&D scientist who has taken drug programs from the bench toward the clinic — and curious how AI is reshaping drug discovery? This is a hands-on role that blends your wet-lab and translational experience with a growing understanding of how scientific data trains the next generation of AI models.

**In this role, you'll:**

- Review technical materials and real-world R&D data in your area of expertise

- Label, classify, and annotate scientific data and model outputs to improve model performance

- Provide expert perspective on key scientific and development decisions (target/modality selection, optimization, trade-offs, risk)

- Help define structure and quality standards for the client's dataset pipeline

- Participate in expert discussions, interviews, and research engagements

**You're a strong fit if you:**

- Have hands-on, non-administrative preclinical R&D experience at a company that develops its own drug assets in-house and has taken programs to the clinic — Must Have

- Work in a core R&D function: discovery biology, medicinal chemistry, protein/antibody engineering, computational, in vivo/translational, pharmacology/PK-PD, toxicology, or CMC/formulation — Must Have

- Have hands-on experience with one or more drug modalities (small molecules, monoclonal antibodies, peptides, ADCs, bispecifics, mRNA, siRNA, ASOs, PROTACs, molecular glues, cell therapies, gene therapies, radioligand therapies, etc.) — Must Have

- Have 5+ years of relevant industry R&D experience (flexible based on depth)

- Have taken a program through lead optimization or IND-enabling/preclinical development (nice to have)

- Have experience at mid-sized, emerging, or resource-constrained biotech — ideally currently outside the top-20 pharmaceutical companies (nice to have)

This is a hands-on preclinical R&D role — likely **not the right fit** if your work is mainly CRO/CDMO services, academic-only, QC/analytical-only, clinical-development-only, diagnostics, or regulatory/medical-writing.

Your work will directly feed into the models reshaping how medicines are discovered, helping intelligent systems reason about real-world pharmaceutical R&D.

**Here are more details about the role:**

- You will interface directly with the client team.

- This is an ongoing, part-time engagement of roughly 10 hours per week.

- Seniority welcome from individual contributor through Director.

Preclinical R&D Expert – In-house Drug Development

- Hold a **role in your organisation's health insurance decision** — you make the final decision, you decide jointly with one or two other people, or you gather the options and make a recommendation that someone else signs off

- Current title such as **Owner, CEO, or President, CFO, Controller, or Head of Finance, HR Director or HR Manager, Office Manager or Operations lead with benefits as part of the job, Benefits or Total Rewards specialist**, or **Executive Assistant or Administrator**

- Work for a **private sector business, a non-profit organisation, a public sector employer (local government, school district, or municipality)**, or a **provider, medical practice, or health system**

- Your organisation has **200 or fewer employees in the United States**

- Your organisation **offers health insurance to employees** — a group health plan you buy directly, coverage through a PEO, or money for employees to buy their own coverage (ICHRA or a stipend)

- Based in the **United States**

- Able to independently complete a ~25-minute online survey

Please note: employees of health plans or health insurers, insurance brokers or benefits advisors, and pharmacy benefit managers (PBMs) are not eligible for this study.

## Engagement Details

Small Employer Benefits Decision-Makers Survey – Health Insurance Purchasing Insights

**About the work**

We're building a high-quality dataset of human preference judgments on AI-generated frontend code. Each task hands you a reference web page — crawled from the real internet, delivered as a full zipped site tree plus screenshots of its default view and, on some pages, additional states reached by hovering, clicking, or scrolling. Alongside it come two model attempts, A and B, each a zipped self-contained site tree. The models only ever saw the screenshots; they never had the source.

You download all three, run them locally, view each at a 1920×1080 viewport, interact with them to reach every required state, then open the source of both attempts and grade them against each other — on visual fidelity per state, and on how the code is actually constructed. Structure and responsiveness are explicitly part of the rubric, not just the render.

This is evaluation work, not authoring. The defining skill is not that you can build a page — it's that you can open someone else's page and tell how it was built and where it cheats.

**Please read before applying**

- Each unit takes roughly 2–3 hours and is timed. This is not microtask work; if you can only offer scattered 15-minute windows, you will not be able to finish a unit.
    
- You need a real local development environment. A tablet, a Chromebook, or a locked-down work machine that cannot run a local static server will not work for this project.
    
- You need at least one completed Mercor engagement, delivered in full. We are not onboarding net-new experts to this project.
    

**What you'll do**

- Render a reference page and two candidate replications at 1920×1080 and judge which is the closer reproduction, state by state.
    
- Diff visual fidelity in detail: box model and spacing, typography (family, size, weight, line-height, letter-spacing), color and border treatment, image and asset handling, z-order and overflow.
    
- Read the source of both attempts and grade construction quality — distinguishing a replication that is genuinely correct from one that merely looks correct at one viewport. Hardcoded pixel offsets, absolute positioning standing in for real layout, inline style soup, a single undifferentiated div tree, or a screenshot pasted in as an `<img>` instead of a rebuilt section.
    
- Test responsiveness: a nav bar that looks right at 1920px but collapses at 1400px is a defect, and you should be able to say precisely why.
    
- Write a specific, evidence-cited justification for every preference. We need "B nests the article body in a single absolutely-positioned div, so the text overlaps the footer below 1600px, while A uses normal document flow" — not "A looks closer."
    
- Use the "this task is broken" escape hatch with judgment: distinguish a task that genuinely cannot be completed from the screenshots provided from one that is merely hard. Over-flagging and under-flagging are both failure modes.
    

**You're a fit if you have**

- 3–8 years of professional web development experience, shipping web interfaces for a living, primarily in frontend or full-stack work.
    
- Fluency across web eras. The reference pages are real crawled sites — one is a small charter-fishing business built in the table-and-image-map tradition, another a corporate press-release page with stacked navigation rows and social share widgets. If your entire career happened inside a modern component framework and you have never authored raw CSS or seen a `<table>` used for layout, you will misjudge many of these pages.
    
- Command of hand-written HTML and CSS: semantic markup, flexbox, grid, media queries, and legacy float- and table-based layouts you can read and reason about. You should be able to look at a rendered layout and predict what's holding it together before opening DevTools.
    
- Browser DevTools as muscle memory — setting an exact viewport, walking the element tree, checking computed styles, watching what a hover handler mutates.
    
- Command-line comfort: unzipping an archive, standing up a static local server because the relative asset paths demand it, and untangling a broken image reference rather than giving up and grading from the screenshot.
    
- Enough JavaScript to read a page's scripts and understand what they do to the DOM, even if you don't write JS daily.
    
- Professional written English. Every task ends in a free-text justification, and a rating without a specific rationale is worth very little.
    

**Equipment**

- A desktop or laptop that displays a 1920×1080 viewport.
    
- Administrator rights on your own machine, so you can install and run a local server.
    

**Nice to have**

- Prior RLHF, preference-labeling, model-evaluation, or structured code-review work — the strongest single signal. Rubric-driven comparison at volume needs almost no ramp here.
    
- Pixel-perfect design-to-code experience: agency work, design systems, template production. Anyone who has had a designer reject a build over four pixels has exactly the fidelity eye this needs.
    
- Accessibility expertise (ARIA, semantic landmarks, heading hierarchy) — you'll notice immediately when an attempt renders a heading as a styled `<span>`.
    
- Familiarity with how LLMs fail at code generation.
    
- Web scraping, archiving, or DOM-parsing background — comfort with messy crawled site trees.
    
- More than one completed Mercor project, and availability in contiguous multi-hour blocks.
    

**Note:** this seat is for practicing web developers. Backend-only, ML/data-science-only, mobile-native-only, and DevOps-only engineers do not have the UI instincts this requires, however strong they are otherwise. Designers who do not code cannot grade the source axes at all. Framework-only engineers who have never authored CSS outside a component library will struggle with the legacy reference pages.

**Domain Expert – Banking (Oracle FLEXCUBE Research)**

To qualify you must use Oracle FLEXCUBE regularly — weekly or more — as a working part of your job, with 2+ years of professional banking experience.

**FLEXCUBE knowledge we require**

_Credit & exposure_

- Calculating current exposure against the bank's credit standard as at a given business date; arrears and headroom calculation
    
- Distinguishing a validation-only posting from a booked transaction against a contract
    
- Reading limits/facility structures; recognizing when an item needs committee sign-off vs. branch-level approval
    

_Customer & relationship records_

- Customer Information File (CIF) structure and relationship hierarchies
    
- Recording contact/interaction history accurately, including on partial or handed-off information
    
- Setting and interpreting review dates and follow-up flags on a customer file
    

_Contracts & core banking operations_

- Contract inquiry and lifecycle screens (origination, drawdown, repayment, release)
    
- Branch lending repayment validation vs. contract booking
    
- Distinguishing what's confirmed vs. assumed when picking up a file mid-process
    

_Reference & product data_

- Product parameter tables, GL mapping, and how product configuration constrains what a transaction can do
    
- Settlement/correspondent references where relevant to a contract
    

_Regulatory & credit standards_

- Applying the bank's own credit standard/policy to determine current risk position
    
- Version/currency awareness — which policy or limit applies as of the current business date
    

_Audit & handoff_

- Recording validations, conclusions, and open items so the next person in the workflow can see exactly what was decided and what's still outstanding
    
- MIS / reporting screens relevant to exposure and customer position
    

**What you'll do**

- Confirm the customer/contract position reflects what actually happened, not what's assumed, especially on partial handoffs
    
- Work out current exposure under the bank's credit standard as at the current business date, and record it with a review date
    
- Distinguish validation-only actions from bookings that affect a contract
    
- Judge completeness: is the full position understood, is anything left open that shouldn't be, is the record ready for the next reviewer or for committee
    
- Verify recorded outcomes are traceable — auditable, not just noted informally
    

**Requirements**

- Frequent Oracle FLEXCUBE use — weekly or more — in your current or recent role
    
- 2+ years of professional experience in banking operations, credit, or a related core-banking function
    
- Reflexive familiarity with credit standards, exposure calculation, and validation-vs-booking distinctions
    
- Bachelor's degree in Finance, Accounting, Business, or a related field; a banking/credit certification (e.g., Chartered Banker – CIOB, Certified Credit Professional) or equivalent hands-on core-banking experience

Corporate/M&A Lawyer (United Kingdom)

Are you a Level 3 / Tier 3 network support engineer interested in data science and autonomous infrastructure? Our client is building vertically integrated networking systems and using the data they generate to power the next generation of AI-driven infrastructure. They're looking for engineers experienced in final escalations, packet analysis, troubleshooting, and RCA workflows to help label, annotate, and structure networking data from real production systems.

This is a hands-on role that blends your L3 troubleshooting and incident-response experience with a growing understanding of how data pipelines are built and used in AI systems.

**In this role, you'll:**

- Review real-world data from deployed networks: logs, configs, telemetry, event streams
    
- Label and classify network behaviors, issues, anomalies, and incident patterns
    
- Help define schemas and structure for large-scale data pipelines that downstream ML models will train on
    

**You're a strong fit if you:**

- Work today as a Level 3 / Tier 3 / Principal Support Engineer keeping existing enterprise infrastructure online and stable — on-call rotation, RCAs, final escalations, troubleshooting outages — Must Have
    
- Have hands-on experience with end-customer enterprise networks (switches, APs, firewalls in retail, healthcare, financial, manufacturing, university, hospitality, etc.) — Must Have
    
- Bring hands-on Wi-Fi/wireless proficiency — enterprise WLAN controllers (Cisco WLC, Aruba, or Meraki), 802.1X/RADIUS, and wireless troubleshooting — Must Have
    
- Do packet-level troubleshooting yourself — Wireshark, tcpdump, SPAN captures
    
- Are curious about how raw infra data becomes machine learning input
    

This is a **maintainer** role — likely not the right fit if your current work is mainly network design/architecture, cloud/SRE, security/SOC, or IT helpdesk.

Your work will directly feed into the pipelines that power client's AI models, and help shape how intelligent systems reason about networks in the real world.

**Here are more details about the role:**

- You will interface directly with the client team.
    
- You are expected to work 30-40 hours/week, with your hours overlapping the Pacific (PT) business day.
    
- This is an individual 1099 contract paid to a personal account — no corp-to-corp or agency billing.
    
- You must be authorized to work in the US or Canada without sponsorship.

AI Data Generalist — Egocentric Video Review

Required: strong research background in any domain.

Generalist Search Expert

We are looking for engineers who build and operate LLM agents in production, and who have real visibility into how agents are actually used inside a company.

You have probably:

- Shipped an agent that real users depended on, and been on the hook when it broke.
    
- Figured out how to tell whether an agent got better or worse after a change.
    
- Run agents that outlive a single request: scheduled jobs, long-running work, cloud sandboxes.
    
- Watched your org build an internal assistant, and seen who adopted it and who quietly did not.
    

We are especially interested in the layers most people do not talk about: internal monoagents wired into company data, shared company memory, reusable skills and playbooks, the tool and MCP surfaces agents call, and how anyone sees what agents did and what they cost.

Applying starts with a short conversational AI interview. No coding, no take-home. We want to hear how you actually think about agent reliability, evaluation, and adoption, and the tradeoffs you have made in real systems. Bring war stories. The messier and more specific, the better.

If that screen stands out, we will invite you to a live 30 minute conversation with our team. We pay $100 to $500 for that conversation, paid on completion of the call, with the amount depending on depth of experience.

If that sounds like you, apply and complete the screen. We review every submission.

Agent Engineer

**Join a leading AI lab's cutting-edge GenAI team to be at the core of the AI revolution, where your expertise fuels the development of the most advanced AI models.**

# 1\. Overview

Join a leading AI lab's cutting-edge GenAI team and help build foundational AI models from the ground up. We're seeking senior image quality experts from film, VFX, animation, and professional photography — VFX and rendering supervisors, colorists, cinematographers, lighting artists, and high-end photographers — with a strong foundation in visual perception, light physics, and pixel-level scrutiny. You will judge, frame by frame, whether an enhanced or upscaled image actually holds up, catching the compression artifacts, noise, aliasing, grain-structure inconsistency, and over- or under-sharpening that typically go unnoticed by the average viewer.

This is a part-time W-2 employment position with Cincinnatus LLC, with the opportunity to be placed at a leading AI Lab as part of their extended workforce.

# 2\. Key Responsibilities

- Evaluate high-resolution video and stills at pixel level, identifying compression artifacts, noise, aliasing, banding, grain-structure inconsistency, and over- or under-sharpening.
    
- Apply an uncompromising focus on the intricate details that typically go unnoticed, and flag where output diverges from professional image-quality standards.
    
- Design and refine evaluation templates and rating guidelines so reviewers apply the same visual-quality bar consistently, including under edge cases.
    
- Translate complex visual details into clear, precise descriptive language that can be captured in data captions and evaluation templates.
    
- Generate your own visual samples for targeted testing and side-by-side comparison.
    
- Collaborate with other subject matter experts and program leads to maintain visual consistency across sequences and across reviewers.
    

# 3\. Core Qualifications

- 5+ years of professional experience in high-end visual evaluation across film, VFX, animation, or professional photography.
    
- Direct professional experience in at least one of the following disciplines:
    
    - **Visual Effects (VFX) Supervisor** — the authority on final image quality, with an elite eye for pixel-level flaws, grain-structure inconsistencies, and visual artifacts.
        
    - **Rendering Supervisor** — accustomed to running dailies and taking ultimate responsibility for visual quality down to the absolute pixel.
        
    - **Lighting Supervisor, Lead, or Artist** — a specialist in illumination and the foundational building blocks of digital video and cinematic motion.
        
    - **Colorist** — deep expertise in color grading, artifact detection, and maintaining visual consistency across sequences.
        
    - **Director of Photography (DP) or Cinematographer** — skilled at framing, capturing visual performance, and critically evaluating over- and under-sharpness in high-resolution images.
        
    - **Effects or Surfacing Artist** — strong command of textures, materials, and the complex simulation of visual elements.
        
    - **High-End Photographer** — deep command of lighting dynamics, depth of field, and color artifacts in high-resolution captures.
        
    - **Director** — particularly those with deep experience directing crowd and background action.
        
    - **Digital Projectionist** — a rigorously trained eye for final-output quality, screen-level fidelity, and visual anomalies.
        
- Training from a university or program with a highly respected film, visual effects, or digital media program.
    
- Reliable access to a 4K-resolution monitor or display to perform precise, pixel-level evaluation.
    
- Familiarity with AI tools and workflows, including the ability to generate your own visual samples for testing and comparison.
    
- Ability to engage reliably for 20 hours per week, with working hours overlapping the PST to EST window.
    
- Fluent in English, with the exceptional ability to translate complex visual details into clear, precise descriptive language.

Visual Quality Expert (Film, VFX & Animation)

**Join a leading AI lab's cutting-edge GenAI team to be at the core of the AI revolution, where your expertise fuels the development of the most advanced AI models.**

## 1\. Overview

We are hiring a senior **finance domain expert** to work directly with a leading AI lab's research and program management teams, improving how frontier AI models reason about real financial work.

Your finance expertise is the substance of this role. You will review the quality of finance knowledge work tasks, write the instruction specs and golden solutions that define what "correct" looks like, and build the benchmarks that show whether the model is genuinely improving. We are looking for a practising specialist rather than a generalist.

This is a full-time W-2 employment position with Cincinnatus LLC, with the opportunity to be placed at a leading AI lab as part of their extended workforce. You will be provisioned with client-issued accounts and equipment, and will work inside the client's own tools alongside their research teams.

**Location:** This is a **hybrid** role based in the **Bay Area, California**. You must live in the Bay Area and work on-site with the client's team multiple days each week, when required. This is not a remote role. If you do not currently live in the Bay Area, you must be willing to relocate there at your own cost before the engagement starts — relocation assistance is not provided.

## 2\. Key Responsibilities

- **Data QA and reviews:** Vet the quality of finance knowledge work tasks and model outputs — spotting missing behaviors, thin reasoning, flawed assumptions, and answers that read well but would not survive professional scrutiny.
    
- **Instruction specs and golden datasets:** Write high-quality instruction specs, produce golden solutions to financial problems, and define new finance tasks that reflect how the work is actually done in practice.
    
- **Benchmarks and domain depth:** Design challenging finance tasks and evaluation sets, and help build finance-specific skills and tools together with the research team.
    
- **Calibration:** Work with client researchers and specialists in adjacent fields to keep standards consistent, translating tacit financial judgment into explicit, teachable criteria.
    

## 3\. Core Qualifications

- **Experience:** 5+ years of substantive, dedicated professional finance experience at a recognized institution — for example an investment bank, asset manager, private equity or credit fund, Big Four firm, a large corporate finance function, or a financial regulator. Generalist roles that only touch finance peripherally do not count.
    
- **Domain depth:** Genuine specialization in at least one core finance discipline, for example corporate finance and FP&A, investment banking and M&A, asset or wealth management, private equity or private credit, quantitative finance and risk management, treasury, or accounting and audit.
    
- **Seniority:** Clear progression to a senior individual-contributor or leadership level — for example Vice President, Director, Principal, Managing Director, Portfolio Manager, Controller, or CFO — with real ownership of analysis and decisions.
    
- **Education and credentials:** An advanced degree from a strong program (MBA, MS, or PhD in finance, economics, accounting, or a quantitative field) and/or a recognized professional credential such as CFA, CPA, FRM, or an actuarial designation. Strongly preferred.
    
- **AI fluency:** Hands-on working use of large language models in your professional work, and the judgment to tell a well-reasoned answer from a plausible-sounding wrong one.
    
- **Availability:** Able to commit reliably to 40 hours per week for an initial engagement of 6 months.
    
- **Location:** Living in the Bay Area, California, and able to work on-site with the client's team multiple days each week, when required. Candidates not currently based in the Bay Area must be willing to relocate there at their own cost; relocation assistance is not provided.

Investment Banking & M&A - Finance Domain Expert

**Join a leading AI lab's cutting-edge GenAI team to be at the core of the AI revolution, where your expertise fuels the development of the most advanced AI models.**

## 1\. Overview

We are hiring a senior **legal domain expert** to work directly with a leading AI lab's research and program management teams, improving how frontier AI models reason about real legal work.

Your legal expertise is the substance of this role. You will review the quality of legal knowledge work tasks, write the instruction specs and golden solutions that define what "correct" looks like, and build the benchmarks that show whether the model is genuinely improving. We are looking for a practising specialist rather than a generalist.

This is a full-time W-2 employment position with Cincinnatus LLC, with the opportunity to be placed at a leading AI lab as part of their extended workforce. You will be provisioned with client-issued accounts and equipment, and will work inside the client's own tools alongside their research teams.

**Location:** This is a **hybrid** role based in the **Bay Area, California**. You must live in the Bay Area and work on-site with the client's team multiple days each week, when required. This is not a remote role. If you do not currently live in the Bay Area, you must be willing to relocate there at your own cost before the engagement starts — relocation assistance is not provided.

## 2\. Key Responsibilities

- **Data QA and reviews:** Vet the quality of legal knowledge work tasks and model outputs — spotting missing behaviors, thin reasoning, and answers that read well but would not survive professional scrutiny.
    
- **Instruction specs and golden datasets:** Write high-quality instruction specs, produce golden solutions to legal problems, and define new legal tasks that reflect how the work is actually done in practice.
    
- **Benchmarks and domain depth:** Design challenging legal tasks and evaluation sets, and help build legal-specific skills and tools together with the research team.
    
- **Calibration:** Work with client researchers and specialists in adjacent fields to keep standards consistent, translating tacit legal judgment into explicit, teachable criteria.
    

## 3\. Core Qualifications

- **Education:** Juris Doctor (JD) from an accredited law school; a highly ranked school is strongly preferred.
    
- **Experience:** 5+ years of substantive post-qualification legal practice at a reputable institution — an established law firm, a corporate legal department, a regulatory body, or a court. Internships and clerkships alone do not count.
    
- **Domain depth:** Genuine specialization in at least one substantive practice area, for example corporate and transactional, litigation and dispute resolution, regulatory and compliance, intellectual property, employment and labor, or tax.
    
- **Seniority:** Clear progression to a senior level — partner, of counsel, counsel, senior associate, senior in-house counsel, or general counsel — with real ownership of matters.
    
- **Licensure:** Active admission to at least one U.S. state bar, in good standing.
    
- **AI fluency:** Hands-on working use of large language models in your professional work, and the judgment to tell a well-reasoned answer from a plausible-sounding wrong one.
    
- **Availability:** Able to commit reliably to 40 hours per week for an initial engagement of 6 months.
    
- **Location:** Living in the Bay Area, California, and able to work on-site with the client's team multiple days each week, when required. Candidates not currently based in the Bay Area must be willing to relocate there at their own cost; relocation assistance is not provided.
    
- Excellent written communication, and the ability to give precise, well-structured written feedback.

Music & Lyrics Expert - Arabic

**Mercor is partnering with a venture-backed AI lab building frontier AI platforms and physics-based foundation models for chemistry, materials science, and drug discovery.** They're extending their platform into new areas of pharmaceutical development and are looking for hands-on **ADC and/or bispecific** experts to help guide what they build.

Are you a preclinical R&D scientist who has taken drug programs from the bench toward the clinic — and curious how AI is reshaping drug discovery? This is a hands-on role that blends your wet-lab and translational experience with a growing understanding of how scientific data trains the next generation of AI models.

**In this role, you'll:**

- Review technical materials and real-world R&D data across ADC and/or bispecific programs
    
- Label, classify, and annotate scientific data and model outputs to improve model performance
    
- Provide expert perspective on key scientific and development decisions (target/modality selection, optimization, trade-offs, risk)
    
- Help define structure and quality standards for the client's dataset pipeline
    
- Participate in expert discussions, interviews, and research engagements
    

**You're a strong fit if you:**

- Have hands-on, non-administrative preclinical R&D experience at a company that develops its own drug assets in-house and has taken programs to the clinic — Must Have
    
- Have direct experience with **ADCs and/or bispecific (or multispecific) antibodies** — Must Have
    
- Work in a core R&D function: discovery biology, medicinal chemistry, protein/antibody engineering, computational, in vivo/translational, pharmacology/PK-PD, toxicology, or CMC/formulation — Must Have
    
- Have 5+ years of relevant industry R&D experience (flexible based on depth)
    
- Have taken a program through lead optimization or IND-enabling/preclinical development (nice to have)
    
- Have experience at mid-sized, emerging, or resource-constrained biotech — ideally currently outside the top-20 pharmaceutical companies (nice to have)
    

This is a hands-on preclinical R&D role — likely **not the right fit** if your work is mainly CRO/CDMO services, academic-only, QC/analytical-only, clinical-development-only, diagnostics, or regulatory/medical-writing.

Your work will directly feed into the models reshaping how medicines are discovered, helping intelligent systems reason about real-world pharmaceutical R&D.

**Here are more details about the role:**

- You will interface directly with the client team.
    
- This is an ongoing, part-time engagement of roughly 10 hours per week.
    
- Seniority welcome from individual contributor through Director.

Preclinical R&D Expert – ADC & Bispecifics

**Join a leading AI lab's cutting-edge GenAI team to be at the core of the AI revolution, where your expertise fuels the development of the most advanced AI models.**

## 1\. Overview

A leading AI lab is teaching its AI to do real enterprise sales work — the kind of multi-step, judgment-heavy workflows that only someone who has actually carried a quota knows how to get right. To do that well, they need seasoned sellers to act as the ground truth: people who can show the model what excellent looks like, catch where it goes wrong, and set the bar its work is measured against.

That is where you come in. As a Sales Domain Expert, you will bring years of real selling experience to auditing sales workflows, building the "golden" reference examples the model learns from, and shaping the rubrics used to evaluate it. This is a role for accomplished enterprise sellers — not general data annotators.

This is a full-time W-2 employment position with Cincinnatus LLC, with the opportunity to be placed at a leading AI lab as part of their extended workforce. This role is fully remote within the United States.

## 2\. What You'll Do

- **Set the standard for "good":** Review multi-step enterprise sales workflows and judge whether the AI handled them the way a strong seller would, flagging what is off and why.
    
- **Build golden trajectories:** Work real sales tasks end-to-end — prospecting, pipeline management, CRM hygiene, reporting, and customer-facing documents — to create the expert reference examples the model is trained on.
    
- **Shape the evaluation:** Pressure-test and refine the rubrics used to score AI outputs so they capture what actually separates great selling from average.
    
- **Work in realistic sandboxes:** Operate inside test environments that mirror a real sales tech stack, completing and simulating workflows across CRM, communication, and billing tools.
    
- **Produce senior-level artifacts:** Create polished, customer-facing materials — pitches, slide decks, and summaries — at the quality a senior sales leader would put their name on.
    

## 3\. Who We're Looking For

- Around 10 years of hands-on experience selling in enterprise environments, with a real feel for the full sales cycle.
    
- A consistent track record of meeting or exceeding your sales quota, which you can speak to in specifics.
    
- Sellers at every level are welcome — quota-carrying individual contributors, managers who lead selling teams, and VPs running regional or global sales organizations.
    
- Day-to-day fluency with the standard enterprise stack (Salesforce, Jira, Confluence, Google Workspace, and Microsoft Office), and the comfort to pick up tools like Slack, HubSpot, Notion, Aircall, Stripe, Intercom, Zoho, and Microsoft Teams.
    
- Genuine depth in CRM administration, sales process management, pipeline tracking, and data-driven reporting.
    
- Strong writing and a good eye for polish — you can turn a complex situation into a clear, professional, customer-facing artifact.
    

## Nice to Have

- Experience working within or alongside a two-sided, AI-powered B2B SaaS creator marketplace — for example, running outcome-based campaigns against contracted performance targets (tracking views, engagement, installs, and sign-ups in real time) and troubleshooting across a connected stack such as Zoho CRM, Jira, Confluence, Freshdesk, Microsoft Teams, and Google Workspace. If this sounds like you, tell us — we are especially keen to talk.

Enterprise Sales Domain Expert

**Join a leading AI lab's cutting-edge GenAI team to be at the core of the AI revolution, where your expertise fuels the development of the most advanced AI models.**

## 1\. Overview

A leading AI lab is building a performance transfer model: one that takes an actor's original performance and carries it faithfully into a new output, holding on to the timing, the emotion, and the small physical choices that make it feel real. The team believes AI should honor the craft of performance, not flatten it.

To get the evaluation right, we are bringing in senior character animators to help define what "good" looks like, critique the current evaluation approach, and shape the pool of reviewers who score model outputs.

This is a part-time W-2 employment position with Cincinnatus LLC, with the opportunity to be placed at a leading AI Lab as part of their extended workforce.

## 2\. Key Responsibilities

- **Establish evaluation standards:** Define clear criteria for when a performance has been captured well, both in emotional resonance and physical fidelity, and point out where current evaluations fall short.
    
- **Curate benchmarks:** Identify strong examples of performances that are easy to capture and ones that are genuinely hard, so the model has meaningful tests to measure against.
    
- **Shape the evaluation pool:** Help define the right profile, expertise mix, and rubric for the human reviewers who assess outputs at scale.
    
- **Collaborate with other experts:** Work alongside fellow subject-matter experts to keep evaluations consistent and accurate.
    

## 3\. Core Qualifications

- **4+ years as a hands-on character animator**, with human or character _performance_ as your core craft.
    
- Verifiable credits on **2 or more feature films, animated features, or AAA game cinematics** at recognized studios.
    
- Direct experience with **facial animation and/or performance capture** — facial keyframe work, motion-capture solving, cleanup or motion editing, or character technical design of facial and performance rigs.
    
- A meticulous eye for micro-expressions, emotional beats, and the subtleties that make a human performance feel authentic.
    
- **AI proficiency:** familiarity with AI tools and workflows, including the ability to generate your own visual samples for testing and comparison.
    
- The ability to translate complex visual details into clear, precise language that can be captured in data captions and evaluation templates.
    
- Able to come on-site in Playa Vista (Los Angeles), CA or New York, NY for in-person working sessions once or twice a month.
    
- (Optional) Reliable access to a 4K-resolution monitor for precise, pixel-level review.
    

## 4\. Who this role is not for

This role is specifically for animators whose primary craft is **character performance**. It is not a fit for directors of photography, lighting or camera specialists, colorists, compositors, editors, or generalist 3D artists. Layout, previsualization, environment and effects work will not qualify on their own.

CAM Programming Expert (Fusion 360)

Mercor is partnering with a major technology company building AI design tooling on a paid research study with senior designers.

The client wants to capture how expert designers think: how you approach a problem, what separates strong craft from weak, and how you decide when something is ready to ship. This is captured in structured, recorded remote sessions. Depending on fit, you'd either be the expert being interviewed or the one running the interview.

What to expect

- Roughly 4–5 hours per task/interview, including prep beforehand and a short review afterward
    
- $250/hour
    

Scope is still being finalized with the client, so structure, timing, volume, and rate may change.

What we're looking for

- Senior-level design experience (product, UX, brand, or adjacent craft disciplines)
    
- A clear point of view on design quality, critique, and shipping standards
    
- A portfolio you can share — a website link is ideal
    

Portfolios are used solely to assess fit for this study and will not be used for model training of any kind. Please only submit work you're free to share publicly — no confidential, unreleased, or NDA-covered material.

Senior Design Expert - Paid AI Design Research Study

**Join a leading AI lab's cutting-edge GenAI team to be at the core of the AI revolution, where your expertise fuels the development of the most advanced Large Language Models.**

# 1\. Overview

Join a leading AI lab's cutting-edge GenAI team and help build foundational AI models from the ground up. We're seeking talented Full-Stack Software Engineers with hands-on production experience across modern application stacks — **Python, Java, Rust, C#, C++, and TypeScript** — to build, integrate, and stress-test real software on top of frontier models before they ship. Engineers work directly with the AI lab's engineering manager on fast-moving projects and are expected to onboard quickly and contribute working code early.

This is a full-time engagement of 40 hours per week.

# 2\. Key Responsibilities

- Build and ship full-stack applications, services, and internal tools — in Python, Java, Rust, C#, C++, or TypeScript — that exercise frontier model capabilities end to end.
    
- Integrate pre-release model APIs into working software, including the surrounding scaffolding: tool interfaces, evaluation harnesses, and telemetry.
    
- Diagnose and document model and integration failure modes surfaced while building, translating engineering observations into clear written feedback for the research team.
    
- Prototype quickly against shifting requirements, delivering working increments with limited up-front specification.
    
- Collaborate with the engineering manager and other engineers to maintain consistency in code quality, architecture, and technical documentation.
    

# 3\. Core Qualifications

- 3+ years of dedicated professional experience building and shipping production software at a recognized, top-tier organization.
    
- Production experience in at least one of Python, Java, Rust, C#, or C++, plus working proficiency in a second language — this cohort is intentionally staffed across multiple language ecosystems.
    
- Hands-on experience across the stack: backend services and APIs, a modern front-end framework (React or equivalent), relational or document databases, and cloud deployment.
    
- Demonstrated ability to onboard onto an unfamiliar codebase and deliver working code quickly with minimal ramp-up.
    
- Demonstrable career progression.
    
- Ability to engage reliably for at least 40 hours/week during weekdays.
    
- Strong written communication skills and the ability to explain complex technical decisions clearly.
