**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.

**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 role is based in the **Bay Area, California**. Day-to-day work is remote, but you must live in the Bay Area and be able to come on-site when required. On-site days are expected to be infrequent.

## 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 come on-site when required.
    
- Excellent written communication, and the ability to give precise, well-structured written feedback.

CAM Programming Expert (Fusion 360)

## About this opportunity

Mercor is working with a leading AI lab to build a large collection of visual tasks to help train advanced AI models.

This project focuses on **counting objects in images**. While counting sounds easy, AI models often make mistakes. They may guess instead of counting, rely on text in the image instead of what they see, count duplicates incorrectly, or miss objects that look similar.

Your job is to source images that can cause these mistakes and clearly document what went wrong.

## What you will do

- Find an image that may cause an AI model to count incorrectly. The image can be original, public domain, or AI-generated
    
- Identify what might confuse the model, such as misleading text, similar-looking objects, duplicates, or an unclear unit of measurement
    
- Test the image with AI models using a simple prompt: **"How many X are there? Return an integer."**
    
- Write additional prompts that give the models more context, and then label the task
    

## What we're looking for

- **Strong written English**: Prompts need to be clear and easy to understand.
    
- **Good attention to detail**: You should be able to notice small details in images and understand what might confuse an AI model.
    
- **Consistency and reliability**: You will work on many tasks, so being careful and consistent is important.
    

Experience with photography, image editing, data labeling, or other detail-focused work is a plus.

### Details

- **Remote:** Work from anywhere
    
- **Pay:** $35/hour

Image Reasoning Generalist

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)

# Domain Expert – Pharmacy (UpToDate Lexidrug)

**To qualify you must use UpToDate Lexidrug (or Lexicomp) regularly - weekly or more - as a working part of your job, with 2+ years of professional pharmacy experience.**

Lexidrug knowledge we require

**Core (required of all candidates)**

- Knows how to work a full medication-list interaction check to completion — not just confirm a single named pair, but judge severity ratings and mechanism of interaction across the whole list
    
- Knows how to weigh contraindications, boxed warnings, and warnings/precautions against a specific patient's situation, not just check whether a flag exists
    
- Knows how to distinguish "not contraindicated" from "appropriate for this patient" — and where in the monograph that second judgment actually gets made
    
- Knows how to reconcile a Special Alert against monograph content when they conflict — recognizes alerts generally take precedence until reconciled
    
- Knows how to apply renal/hepatic dose-adjustment logic and calculators correctly given current patient data (labs, weight), not just plug in numbers
    

**Specialized depth (strong working knowledge in at least 2–3 of the following)**

- Trissel's IV Compatibility (physical/chemical incompatibility vs. physiological interaction — knows these are distinct problems, not one nested in the other)
    
- Pediatric/weight-based dosing
    
- Beers Criteria / geriatric-specific precautions
    
- Pregnancy and lactation risk categories
    
- REMS and prescribing/access restrictions (controlled substance scheduling, restricted distribution programs)
    
- Therapeutic class comparison for alternatives (allergy, shortage, formulary substitution)
    
- Drug I.D. and patient education / multi-language handouts
    

What you'll do

- Confirm an interaction, dosing, or contraindication finding holds up against the patient's **full** medication list and chart — not just the two drugs named in the question
    
- Catch missed interactions, stale patient data (outdated labs/weight) driving a wrong dose, and monograph guidance superseded by a newer Special Alert
    
- Judge completeness: is the full clinical picture (all active meds, current labs, comorbidities) accounted for, or was the question scoped too narrowly
    
- Distinguish "permitted" from "appropriate" — flag when a drug clears interaction/contraindication checks but is still a poor choice for this specific patient
    
- Verify that a correct clinical conclusion is actually **carried through** — order updated, prescriber notified, chart/note documented — not just identified and left there
    

Requirements

- **Frequent Lexidrug (or Lexicomp) use - weekly or more - in your current or recent role**
    
- **2+ years of professional pharmacy experience, inpatient/hospital setting strongly preferred**
    
- Reflexive use of Interactions, Trissel's, and monograph sections; can spot a missed interaction, a stale dose calculation, or superseded guidance on sight
    
- PharmD and active pharmacy license, or equivalent verification-heavy clinical experience
    
- Strong working knowledge in at least 2–3 specialized areas above, tied to your practice setting (e.g., ICU, oncology, pediatrics, geriatrics)
    
- Comfort judging whether a correct clinical finding was properly followed through into the chart, order, and care-team communication
    
- Prior data annotation, labeling, or AI evaluation experience is a plus

Pharmacist

We're looking for experienced machine learning researchers with hands-on experience training and improving deep learning models end-to-end, across vision and language. You'll work on well-scoped empirical open-ended ML research problems.

## Responsibilities

- Train image classifiers and generative image models from scratch, and fine-tune open-weight language models.
- Get the most out of limited data, compute, and model-size budgets.
- Make models robust — to adversarial inputs and to adversarial conversations.
- Compress models to meet hard size and latency constraints without sacrificing accuracy.
- Diagnose and resolve training issues.

## Requirements

We are looking for candidates with strong expertise in one or more of the following areas:

**Adversarial Robustness**

Experience with:
- Adversarial training of image classifiers (e.g. PGD-based training, TRADES).
- Evaluating robust accuracy under standard threat models (e.g. L∞ attacks, AutoAttack) and avoiding gradient-masking pitfalls.
- Managing the robustness–accuracy trade-off and robust overfitting.

**Efficient Computer Vision**

Experience with:
- Training image classifiers end-to-end, especially for fine-grained recognition (many visually similar classes, few examples per class).
- Model compression: quantization, pruning, and knowledge distillation from large teachers into small students.
- Deploying models under hard size or latency budgets (on-device, edge, or embedded settings).

**Generative Image Modeling**

Experience with:
- Training image generative models from scratch: diffusion models, GANs, VAEs, or flow-based models.
- Iterating against sample-quality metrics such as FID.
- Training-efficiency tricks that produce good generators quickly and at small parameter counts.

**LLM Post-Training & Behavioral Robustness**

Hands-on experience with one or more of:
- Supervised fine-tuning and preference optimisation (DPO, RLHF, RLAIF) of open-weight language models, including building your own datasets via synthetic generation, noisy or weak supervision, and rejection sampling.
- Shaping conversational behaviour over multiple turns: resistance to persuasion and sycophancy, calibrated confidence, and knowing when to accept corrections.
- Alignment-style fine-tuning that changes a specific behaviour while preserving general capability.

**Multilingual Pre-training**

Experience with:
- Training multilingual or low-resource-language models from scratch.
- Tokenizer design across scripts and typologically diverse languages.
- Balancing highly unequal per-language data (sampling temperatures, cross-lingual transfer) in data-constrained regimes.

**Additional Areas of Interest**

Experience in any of the following is a plus:
- Scaling laws and training-efficiency research.
- Curriculum learning and data ordering.
- Model evaluation: benchmark construction, contamination control, statistically sound comparisons.
- Uncertainty estimation and model calibration.
- Data augmentation and synthetic data for robustness.

## General Qualifications

- 3+ years of machine learning research experience (PhD research counts toward this requirement).
- Strong experience with PyTorch, JAX, TensorFlow, or similar ML frameworks.
- Degree from a top-100 university, experience at a FAANG or comparable AI company, or an equivalent research track record through publications or impactful open-source contributions.

## Why Join

- Work on cutting-edge machine learning research.
- Collaborate with leading AI researchers on challenging, high-impact projects.
- Flexible, project-based work with competitive compensation.

We're looking for engineers who have shipped production search systems (especially agentic ones now that we're in the era of LLMs and agents) and are thinking hard about the requirements and optimizations of those systems.

You've probably:

- Owned relevance or retrieval on a system real users depended on
    
- Decided how to quantify impact and improvements with these systems.
    
- Built out systems related to agentic search.
    
- Scaled data infrastructure to power modern search systems.
    

This is a 25-minute conversational interview. No coding, no take-home. We want to hear how you actually think about search quality, evaluation, and the tradeoffs you've made in real systems. Bring war stories — the messier and more specific, the better.

If your interview stands out, we'll follow up with a paid 30-minute live conversation with our team — $200 for your time, paid on completion of the call.

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

- Generate high-quality human data: annotate failures, classify vulnerabilities, and flag systemic risks
    
- Apply structure: follow taxonomies, benchmarks, and playbooks to keep testing consistent
    
- Document reproducibly: produce reports, datasets, and attack cases customers can act on
    

**Who You Are**

- You bring prior red teaming experience (AI adversarial work, cybersecurity, socio-technical probing)
    
- You’re curious and adversarial: you instinctively push systems to breaking points
    
- You’re structured: you use frameworks or benchmarks, not just random hacks
    
- You’re communicative: you explain risks clearly to technical and non-technical stakeholders
    
- You’re adaptable: thrive on moving across projects and customers
    

**Nice-to-Have Specialties**

- Adversarial ML: jailbreak datasets, prompt injection, RLHF/DPO attacks, model extraction

Mercor is partnering with a leading AI research organization to engage experienced UI/UX and product designers for a project focused on evaluating how well AI systems perform real-world digital product design work. Rather than producing deliverables yourself, you will define what excellent work looks like: designing task-specific grading criteria and scoring completed work samples with rigorous, well-reasoned written justifications.

**2\. Key Responsibilities**

- Design precise, task-specific grading criteria for real-world digital product and UX deliverables (design systems and component libraries, responsive UI layouts and dashboards, end-to-end product flows such as onboarding, checkout, and booking, logged-in customer portals, UX writing and product content, and design-to-engineering/production handoff)
    
- Score AI-generated and human work samples against those criteria, with detailed written justifications for every score
    
- Apply consistent, evidence-based judgment so that scores are reproducible and defensible
    
- Incorporate structured feedback from senior reviewers and iterate quickly on your work
    

**3\. Ideal Qualifications**

- 5+ years of professional experience in product design, UI/UX, or design systems for real digital products (not brand or marketing sites)
    
- Background at leading digital-product and UX studios, in-house product-design teams at major product-led companies, or e-commerce and marketplace companies with sophisticated customer portals and dashboards
    
- Experience across one or more relevant tracks: Product / UI / Design Systems Designer, UX Lead, UX Writer / Content Designer, or digital Product / Business Analyst
    
- Deep fluency in the day-to-day craft: interaction and visual design, design systems, responsive layouts, end-to-end product flows, prototyping and production handoff in Figma, and articulating critique the way a design or UX lead would in a review
    
- Exceptionally strong written communication, with the ability to explain exactly why a piece of work does or does not meet the bar for a real product and its users
    
- Detail-oriented, consistent, and comfortable having your judgment reviewed and calibrated against peers
    
- Prior experience with AI training, evaluation, or human-data projects is a strong plus
    

**4\. Application Process**

- Submit your resume, portfolio, or relevant professional background to get started
    
- Qualified applicants may be asked to complete a brief assessment or submit additional information
