**Summary**

You send us footage and a brief, we send you back a finished edit, free of charge. No cost, no upsell, no catch. We have talented video editors on standby who are ready to help and can ensure that your videos are delivered back to you within the time constraints you provide.

**What You'll Get**

A completed edit of your footage, built to the brief you give us, free.

**What We Need From You**

- **The raw footage.** Everything you'd hand a freelance editor: all usable clips, b-roll, separate audio, logos, graphics, any assets you want included.
    
- **A detailed brief.** The more specific, the better the result. Useful things to include:
    
    - Where it's going (Instagram, YouTube, your website, a trade show loop) and target length
        
    - Tone and pacing — punchy and fast, calm and documentary, something else
        
    - Music preferences, or whether you're supplying a track
        
    - Captions or subtitles, and in what style
        
    - Brand colors, fonts, logo placement
        
    - Moments that must stay in, and anything that must come out
        
    - One or two example videos whose style you like
        
    - Any deadline you're working toward
        

**How Your Footage Is Used**

We want to be explicit about this:

- **Your footage is used to evaluate AI model capabilities on real-world editing tasks — how well models handle an actual brief with actual material.**
    
- **Your footage is not used as training data.**
    
- **It isn't resold, published, or shared outside this evaluation work.**
    

**Who This Is For**

Small businesses, solo creators, nonprofits, and anyone sitting on footage they haven't had the time, budget, or software to turn into something finished. No prior editing experience needed — you don't have to know the terminology, just what you want the video to feel like.

**Before You Submit**

Please confirm you own the footage or have the rights to use it, and that anyone clearly identifiable in it has agreed to appear

## About the work

We are building high-fidelity simulated work environments used to evaluate and improve AI agents on real marketing work. Each environment reproduces a marketing org's actual tool surface — email, storage, CRM, project management, social media management, web analytics, AEO/SEO, ads, CMS, product analytics and support — populated with realistic documents, dashboards, personas and deliberately planted problems.

You will help design and pressure-test the Brand Marketing environments: the briefs, the artifacts, the judgment calls a strong practitioner would make, and the errors a weaker one would miss.

## What you will do

- Design task briefs drawn from work you have actually done in brand marketing, including what the task is really testing — the planted issue and the decision a strong practitioner should reach
- Specify the documents, dashboards, personas and tool states a realistic version of that task requires
- Write or review the reference answer and the criteria that separate a strong response from a plausible-but-wrong one
- Review AI agent attempts and judge them against your own standard

Tasks span the capabilities we measure: diagnosing what happened from messy or conflicting data, prioritizing and making tradeoffs, planning and executing, QA and reconciliation, triage and escalation, research and evaluation, reporting, and orchestrating multi-step work across several tools.

## Brand Marketing scope

Brand and share-of-voice analysis, messaging consistency across regions and channels, distinctive asset management, and channel and tactic decisions.

## Who we are looking for

- Hands-on practitioner experience in brand marketing — you have owned positioning, brand tracking and brand investment decisions
- Comfortable reading brand tracking studies, share-of-voice data and Google Analytics 4
- Prior experience building AI training environments, RL environments or simulated case studies is strongly preferred
- Rubric Academy or Rubric Bootcamp certification is strongly preferred
- Clear written reasoning — much of the value is in explaining why a decision is right

Marketing Expert — Organic Growth (AI Agent Environments)

Evaluate the quality, correctness, and hardware-appropriateness of Neuron Kernel Interface (NKI) development tasks used to train and evaluate a frontier AI lab's models. You'll assess CUDA→NKI migration fidelity, Trainium-specific performance-optimization quality, and cross-platform numerical-correctness standards — and provide clear, rubric-based written feedback.

Basic Qualifications
• 2+ years of hands-on experience developing or optimizing kernels using the Neuron Kernel Interface (NKI) targeting AWS Trainium/Inferentia2 hardware
• Strong understanding of NKI-specific development patterns: tile-based computation, SBUF/PSUM/HBM memory-hierarchy management, partition-dimension constraints, and DMA orchestration
• Demonstrated experience assessing CUDA→NKI migration quality
• Familiarity with Trainium-specific performance profiling (NeuronCore pipeline utilization, tensor-engine throughput, memory-bandwidth bottlenecks)
• Experience defining or evaluating cross-platform numerical-correctness standards (GPU vs Trainium accumulation order, rounding behavior, mixed-precision semantics)

Preferred Qualifications
• Direct experience with AWS Neuron SDK, Neuron Compiler internals, or contributions to NKI kernel libraries
• Prior CUDA or Triton kernel development
• Familiarity with Trainium hardware specifications (NeuronCore-v2 architecture, on-chip SRAM topology, supported data types: FP32/BF16/FP8/INT8)
• Experience benchmarking ML training workloads on Trn1/Trn2 instances

Trainium (NKI) Kernel Expert

Evaluate the quality, correctness, and completeness of GPU/accelerator kernel development tasks used to train and evaluate a frontier AI lab's models. You'll assess numerical correctness, performance-benchmarking fairness, task scoping, and compilation/runtime validity across diverse kernel task types — and provide clear, rubric-based written feedback.

Basic Qualifications
• 3+ years of hands-on experience developing, optimizing, or verifying GPU/accelerator kernels in at least two of: CUDA, Triton, NKI, or Pallas (JAX)
• Strong understanding of numerical-correctness criteria for kernels (absolute/relative/ULP tolerances, reference-implementation selection)
• Demonstrated experience with performance profiling and benchmarking (nsight, ncu, roofline analysis, or framework-native profilers)
• Familiarity with common compilation and runtime failure modes (driver mismatches, OOM, launch-configuration errors, shape/stride mismatches, autotuning failures)
• Experience with at least three kernel task types: generation from specification, translation/lowering across frameworks, migration between hardware targets, debugging, performance optimization, or operator fusion

Preferred Qualifications
• Experience across both NVIDIA GPU (CUDA/Triton) and custom-accelerator (NKI/Pallas/TPU) ecosystems
• Background in compiler engineering, MLIR, or intermediate-representation lowering
• Understanding of memory-hierarchy optimization (shared-memory tiling, register pressure, bank conflicts, coalescing patterns)
• Contributions to kernel libraries (cuBLAS, cuDNN, Triton community kernels, JAX/XLA custom calls)

GPU Kernel Expert

Evaluate the quality, fidelity, and completeness of vulnerability-reproduction and remediation tasks used to train and evaluate a frontier AI lab's models. You'll assess whether CVE reproductions are faithful, fixes are sound, verification logic is rigorous, and Docker-based lab environments accurately recreate exploitable conditions — and provide clear, rubric-based written feedback.

Basic Qualifications
• 3+ years of hands-on experience in application security, penetration testing, or vulnerability research
• Strong understanding of CVE vulnerability taxonomy and severity frameworks (CVSS, CWE, CAPEC)
• Demonstrated expertise in secure coding and remediation across common vulnerability classes (SQL injection, command injection, buffer overflow, deserialization, SSRF, misconfigurations, privilege escalation)
• Experience designing or evaluating two-part verification logic (functionality tests + vulnerability tests)
• Proficiency with Docker and Docker Compose for multi-container vulnerability reproduction environments

Preferred Qualifications
• OSCP, GPEN, GWAPT, or equivalent offensive-security certification
• Experience with CVE disclosure, responsible vulnerability reporting, or maintaining exploit proof-of-concept code
• Background in DevSecOps, CI/CD security gating, or SAST/DAST tooling
• Prior technical content review, assessment design, or QA for security-focused engineering tasks

CVE Vulnerability Expert

**About the Role**

Mercor is hiring **Korean-speaking reviewers** to evaluate recorded sessions with a voice-and-camera AI assistant. You will watch each session, compare what the assistant said against what was actually visible in the video, and score it against a detailed rubric.

Your written comments are the deliverable. What you flag as a failure is what gets fixed first. This is judgment work, not volume work.

**Key Responsibilities**

- Review recorded sessions in which a user speaks to an AI assistant while their camera streams whatever is in front of them.
    
- Compare the assistant's responses against what was actually visible in the video feed, and identify hallucinated or fabricated visual detail.
    
- Score each session across visual interpretation, accuracy, relevance, response timing, and whether the assistant used spatial and directional language ("to your left", "move your finger up") rather than purely visual description.
    
- Judge whether the assistant appropriately warned the user when its answer could affect their health, physical safety, or financial security, and whether that warning was timely and proportionate.
    
- Write detailed open comments that support every score with concrete evidence from the session.
    
- Capture the conversation turn by turn in the intake form.
    

**Required Qualifications**

- Native or native-level **Korean**, spoken and written.
    
- Clear, precise written Korean.
    
- **An Android phone with a working camera and microphone. This is mandatory for the project.**
    
- Attention to detail and the discipline to apply a rubric consistently, without substituting your own criteria along the way.
    
- Professional English reading comprehension; the scoring guide is written in English.
    

**Preferred Qualifications**

- Prior data annotation, linguistic QA, content moderation, or AI model evaluation experience.
    
- Training in linguistics, translation or interpreting,
    
- An ear for regional register: recognizing when the assistant's Korean sounds unnatural or non-native.
    

**Additional Information**

- Start date: Immediate. High volume of work between 26 to 31 Aug is expected.
    
- Content note: some sessions involve situations where a wrong answer would carry real consequences, such as identifying medication, checking whether food has spoiled, crossing a street, or reading bank card details. There is no graphic or violent content, but you will evaluate cases with safety implications, and part of the work is flagging when the assistant failed to warn about the risk.

AI Session Annotator (Korean)

**About the Role**

Mercor is hiring **Japanese-speaking reviewers** to evaluate recorded sessions with a voice-and-camera AI assistant. You will watch each session, compare what the assistant said against what was actually visible in the video, and score it against a detailed rubric.

Your written comments are the deliverable. What you flag as a failure is what gets fixed first. This is judgment work, not volume work.

**Key Responsibilities**

- Review recorded sessions in which a user speaks to an AI assistant while their camera streams whatever is in front of them.
    
- Compare the assistant's responses against what was actually visible in the video feed, and identify hallucinated or fabricated visual detail.
    
- Score each session across visual interpretation, accuracy, relevance, response timing, and whether the assistant used spatial and directional language ("to your left", "move your finger up") rather than purely visual description.
    
- Judge whether the assistant appropriately warned the user when its answer could affect their health, physical safety, or financial security, and whether that warning was timely and proportionate.
    
- Write detailed open comments that support every score with concrete evidence from the session.
    
- Capture the conversation turn by turn in the intake form.
    

**Required Qualifications**

- Native or native-level **Japanese**, spoken and written.
    
- Clear, precise written Japanese.
    
- **An Android phone with a working camera and microphone. This is mandatory for the project.**
    
- Attention to detail and the discipline to apply a rubric consistently, without substituting your own criteria along the way.
    
- Professional English reading comprehension; the scoring guide is written in English.
    

**Preferred Qualifications**

- Prior data annotation, linguistic QA, content moderation, or AI model evaluation experience.
    
- Training in linguistics, translation or interpreting,
    
- An ear for regional register: recognizing when the assistant's Japanese sounds unnatural or non-native.

**About the role**

We're hiring experienced legal reviewers to create rubrics and run quality control on large volumes of processed legal documents. This is a review and verification role — not drafting, not advisory.

You'll work across the full range of commercial legal document types: commercial contracts, employment and HR records, IP and technology agreements, regulatory filings, corporate records, insurance policies, financing and debt instruments, litigation files, real estate documents, and tax filings. Breadth matters far more than great depth in any single practice area.

**What you'll do**

- Create rubrics to grade legal documents against that can be understood and applied by a layman
    
- Review processed legal documents against a written QC rubric, checking that every identifying and sensitive element has been correctly handled
    
- Flag and categorise defects, and escalate ambiguous cases for adjudication
    

**What we're looking for**

- US-based, qualified lawyer with 3+ years' post-qualification experience, ideally in-house or as a generalist commercial counsel
    
- Comfort moving across many document types
    
- Experience in managed document review, e-discovery, contract management, or data privacy is a strong advantage
    
- Demonstrable precision and consistency on high-volume review work
    
- Able to follow a written protocol closely, and to improve it

Real hands on Adobe Premiere video editing/postproduction experience

Adobe Premiere Expert

Mercor's People team is building its compensation and equity foundation from scratch. We want to think it through with people who have done it before.

We're looking for Total Rewards practitioners with depth in **one or both** of the following. Either one on its own is enough.

**Compensation design & architecture**

- Built salary bands, leveling frameworks, and job architecture from the ground up
    
- Owned an annual compensation cycle: merit planning, promotion decisions, bonus programs, equity refresh
    
- Benchmarked against a peer set you then had to defend to a skeptical exec team
    
- Designed incentive structures that were simple, credible, and changed behavior
    

**Equity program management**

- Designed option and RSU programs: grant guidelines, pool planning, vesting structures, refresh philosophy
    
- Worked through 409A valuations, plan governance, and grant administration at a venture-backed company
    
- Built the modeling and communication that lets candidates and employees understand what their equity is worth
    

Those two are what we screen on. Nothing below is required. If you have the whole Total Rewards picture, say so.

**Also valuable**

- Compensation philosophy, benchmarking methodology, pay equity and pay transparency
    
- Compensation design for a global or contractor workforce at scale
    
- Benefits program design, HRIS and compensation tooling
    
- Executive compensation, plan governance, or equity through IPO readiness
    

**Context**

Mercor is a Series C company at a $10B valuation, scaling from roughly 500 employees, with a large global contractor network alongside a growing full-time workforce. Nothing is settled yet: what the compensation philosophy should be, how levels map across very different functions, how equity gets granted and explained.

**How this works**

Applying starts with a short screen. If your background fits, we'll invite you to a paid conversation about a live question we're facing. You're paid for it whether or not anything follows.

Rate is $50–$200/hr depending on depth of experience. Engagements run a few hours at a time, scoped to one question.

We review every submission.

**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.

You will review the quality of insurance 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 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 insurance knowledge work tasks and model outputs, spotting missing behaviors, thin reasoning, flawed actuarial assumptions, misapplied policy language, 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 insurance and actuarial problems, and define new tasks that reflect how the work is actually done in practice.
    
- **Benchmarks and domain depth:** Design challenging insurance 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 insurance judgment into explicit, teachable criteria.
    

## 3\. Core Qualifications

- **Credentials:** Either an actuarial credential (FSA, ASA, FCAS, or ACAS) or an active state insurance license in adjusting, underwriting, or broking, for example an all-lines adjuster license. Actuarial candidates are expected to hold a degree in actuarial science, mathematics, statistics, or a related quantitative field.
    
- **Experience:** 4+ years of substantive insurance experience at a carrier, reinsurer, broker, adjusting firm, or insurance regulator.
    
- **Domain depth:** Genuine specialization in at least one area, for example life and annuity, group life and disability, property and casualty, health, reinsurance, pricing and reserving, enterprise risk management, claims adjudication, or underwriting.
    
- **Seniority:** Clear progression to a senior level, for example Actuary, Senior Actuary, AVP, Director, Chief Actuary, Claims Manager, or Head of Underwriting, with real ownership of a book, a reserve, or a claims portfolio.
    
- **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

# 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)

**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

**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.

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.

We’re looking for UK or Europe-based generalist experts to help train and evaluate frontier AI models. In this role, you’ll review and assess a wide range of everyday professional content — documents, slides, spreadsheets, and other written materials — judging them for quality, accuracy, clarity, and completeness. Your feedback directly shapes how AI systems reason about and produce real-world work product.

This is a great fit if you’re a sharp, detail-oriented generalist who’s comfortable moving across different formats and subject areas. You don’t need deep specialization in any one field — strong judgment, careful reading, and clear written reasoning matter most.

**What you’ll do**

- Review and evaluate documents, slides, spreadsheets, and similar materials for quality and correctness
    
- Provide clear, well-reasoned written feedback and ratings
    
- Compare and rank AI-generated outputs against defined criteria
    
- Flag errors, inconsistencies, and gaps in reasoning or formatting
    

**What we’re looking for**

- Bachelor’s degree (minimum requirement)
    
- Based in the UK or Europe
    
- Excellent reading comprehension and written communication in English
    
- Strong attention to detail and sound judgment across varied subject matter
    
- Comfort working independently across common productivity tools (docs, slides, sheets)
    

No prior AI or machine-learning experience is required — we’ll provide the guidelines and context you need to succeed.

Generalist Expert (US/Canada)

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.

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.
    
- Excellent written communication, and the ability to give precise, well-structured written feedback.
