We're looking for everyday users of Meta Muse or Instinct who have used the app for at least 2 weeks. Each week you'll keep using the assistant across different parts of your life (at least 3, e.g. work, health, errands, social), then log and rate the proactive messages it sends you. You'll also export your weekly conversations with personal details removed. This is an ongoing study with the same group of raters each week.

AI Assistant User – Weekly Feedback Study

## About the work

We are building expert-authored forecasting and research data used to evaluate and improve AI models on real political and financial analysis. Each task asks a practitioner to reason from a fixed evidence cutoff — no hindsight — and document the judgment a strong analyst would have made at that moment.

This role covers political report authorship: elections, polling, and political-risk events.

## What you will do

- Author point-in-time political reports and forecasts from a stated evidence cutoff
    
- Make and document directional judgments about polling, win probabilities, and market-implied odds
    
- Explain the causal mechanism behind an event's expected political and market impact
    
- Review model-generated analyses and grade them against your own standard
    

## Who we are looking for

- Local political analysts with hands-on experience on specific races in swing states: current or upcoming Senate, governor, or statewide contests, or recent cycles in the same state
    
- On-the-ground knowledge of the electorate, the candidates, and the local political environment, from roles such as university political scientist, state or regional pollster, state-level campaign or party analytics staff, or state political-risk analyst
    
- A record of making live judgments about polling, win probabilities, or odds in those races — not retrospective commentary
    
- Strong polling literacy and causal event analysis
    
- Typically 8+ years of direct experience, or unusually strong evidence of equivalent performance
    

Backgrounds we look at first: political science departments and survey research centers at universities in the target states, state and regional pollsters, state-level campaign and party analytics teams, and decision desks or race-ratings outlets with state-specific coverage. National forecasting or political-risk experience is welcome when paired with deep knowledge of a specific state. Brand-name experience is a strong first-pass signal but is not a hard requirement — direct experience and performance on the work sample determine who qualifies.

## Not a fit

- Profiles whose experience is mainly international politics, geopolitics, or country risk, with little or no work on US races
    
- Analysts who have not worked on a current or recent US race in the state they would cover
    
- Pure communications or journalism profiles without demonstrated forecasting, polling, or probabilistic judgment
    
- Academic profiles whose work is purely theoretical, with no analysis of live races
    

## Point-in-time discipline

Every task is graded on reasoning from the stated cutoff without hindsight, data leakage, confidential information, or material non-public information.

**About the work**

Mercor is assembling a panel of professional video editors to build post-production tasks used to train and evaluate AI agents. Each task gives an AI agent what you'd hand a junior editor: source footage, a brief, and a deliverable spec, plus a hidden answer key or rubric so the finished video can be scored on the result, not on a text answer.

You will:

- Contribute original footage you shot and fully own (or source openly licensed footage) and author realistic editing briefs from it.
    
- Build each task end to end in your own editing software: cut, introduce defects or distractors where the task calls for them, and produce the reference edit a correct result is judged against.
    
- Write the grading criteria — concrete, checkable standards with the editorial reasoning behind them.
    
- Blind-solve tasks built by other editors and write up a step-by-step solution.
    

**Background we're looking for**

- 5+ years editing professionally in film and TV, commercials, broadcast news, or creator and social production, owning deliverables end to end.
    
- Fluent in at least one professional editor (Premiere Pro, DaVinci Resolve, Final Cut Pro, Avid Media Composer), including basic color and audio cleanup.
    
- Comfortable with delivery specs: resolution, frame rate, codecs, audio channel layouts and frame-accurate cuts.
    
- Strong plus: a library of unpublished original footage you shot and fully own, with people on camera who will sign an appearance release. The more, the better.
    

**The application**

1. Submit your resume and a link to your reel or portfolio.
    
2. Complete a short AI interview about your editing background.
    
3. Answer a few questions about your footage: what you have, whether you own it outright, and whether the people in it consent to its use.
    

**Before you apply**

- Not open to residents of California.
    
- Expect about 12 hours/week.

Database Systems Evaluation Expert

**Help a leading AI lab ensure its models respond to people with care, balance and sound judgment.**

# 1\. Overview

A leading AI lab is seeking behavioral health experts to help evaluate and improve how its AI models handle sensitive, everyday conversations. People increasingly turn to AI for support with relationships, family dynamics, emotional wellbeing, personal beliefs and difficult life decisions. These conversations rarely involve crisis content, but they are exactly where a model's judgment matters most: whether it stays balanced, avoids taking sides, resists telling people what they want to hear, respects a person's beliefs without endorsing or dismissing them, and understands the limits of its role. You'll review these interactions, assess whether the model's responses are appropriate, neutral and safe, and help the lab's researchers define what good looks like. If you bring professional experience in mental health, counseling, social work or behavioral science, and you can articulate clearly why one response serves a person better than another, this role is for you. This is a part-time commitment of at least 20 hours per week, with the option to increase to up to 40 hours per week.

This is a 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 conversations between users and AI models across topics such as relationship and family advice, emotional wellbeing, spiritual and metaphysical questions, and unconventional or unfounded beliefs, and assess whether responses are neutral, appropriate and safe.

- Identify patterns of concern, including excessive agreement, taking sides, reinforcing distorted or unfounded beliefs, moralizing, or overstepping into clinical or directive advice, and document them with clear written rationale.

- Develop rubrics, guidelines and reference responses that define a balanced, supportive and appropriately bounded reply, grounded in established practice from counseling and behavioral health.

- Design test scenarios and conversations that probe how models handle sensitive but non crisis topics.

- Collaborate with the lab's researchers and fellow experts to keep evaluation standards consistent, calibrated and well documented.

# 3\. Core Qualifications

- A degree in psychology, counseling, social work, behavioral health, behavioral science, human services or a closely related field, or equivalent professional experience in the mental health field.

- 3+ years of professional experience supporting people in a mental health, counseling or social services setting, for example as a therapist, counselor, clinical social worker, psychologist, psychiatric nurse, case manager, crisis counselor, peer support specialist or mental health advocate. Clinical licensure (for example LMFT, LCSW, LPC, LMHC, PsyD or PhD) is valued but not required.

- Demonstrated ability to remain neutral and nonjudgmental across diverse perspectives, relationships, belief systems and worldviews, and to explain the reasoning behind a professional judgment.

- Working familiarity with concepts such as sycophancy, cognitive distortions, healthy boundaries and client centered approaches such as motivational interviewing.

- Ability to engage reliably for at least 20 hours/week during weekdays.

- Strong written communication skills and the ability to deliver precise, well structured written feedback.

**Help a leading AI lab define what great design looks like, and build the prototypes that prove it.**

# 1\. Overview

A leading AI lab is looking for senior product designers and design-minded engineers with exceptional taste to help shape how its AI models design and build for the web and for games. You'll work directly with the lab's researchers to define what "great" looks like in UI and UX, and you'll build high-quality prototypes that show it. If you care deeply about great interfaces, like to prototype in code or with AI tools, and can explain why one design works better than another, this role is for you. This is a full-time commitment of 40 hours per week.

This is a 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

- Partner with AI researchers to identify best-in-class UI and UX patterns, and turn them into clear principles and rubrics that define what great design looks like.
    
- Build polished, interactive web prototypes, in code or with AI-native tools such as Cursor, v0, Lovable or Bolt, that showcase strong and diverse design patterns across many product categories.
    
- Review AI-generated interfaces and prototypes, and give specific, actionable written feedback on layout, hierarchy, interaction, motion and visual polish.
    
- Explore a wide range of visual styles, frameworks and animation approaches, from focused productivity tools to playful consumer apps and games.
    
- Collaborate with other designers and researchers to keep standards consistent and keep raising the quality bar.
    

# 3\. Core Qualifications

- 7+ years of experience as a product designer, design lead, design engineer, or creative front-end engineer at a product- or design-led company (for example Apple, Airbnb, Stripe, Figma, Linear, Spotify or Notion) or a top design agency.
    
- Hands-on prototyping skills: you build working web prototypes yourself, in code (HTML, CSS, JavaScript, React, Tailwind) or with AI-native tools (Cursor, v0, Lovable, Bolt, Framer).
    
- A strong grounding in user-centered design, interaction design and rapid prototyping.
    
- Senior-level design judgment, and the confidence to set direction and explain clearly why a design works.
    
- Ability to engage reliably for 40 hours/week during weekdays.
    
- Clear written communication and the ability to give precise, constructive design feedback.
    

**Nice to have:** Fluency with motion and animation (Framer Motion, GSAP, Rive, Lottie, After Effects) or 3D and WebGL, and game design experience in 2D or 3D. You don't need all of these to apply.

## About the work

**CritPt** is a public benchmark of research-level physics challenges, built to test whether frontier AI models can carry out genuine physics research reasoning rather than textbook problem solving. The benchmark paper is **[arXiv:2509.26574](https://arxiv.org/abs/2509.26574)** and we recommend reading it before applying. It will tell you quickly whether this work interests you.

We are engaging physicists to work on research-level physics problems in their own subfield. Depending on where your publication record fits, that can mean creating problems, solving them, reviewing completed work, or auditing it. We agree the specific assignment with you once you are matched to an area.

This is research-grade work rather than volume work. Whatever you produce has to be complete enough for another specialist in your subfield to follow and verify independently, so written reasoning is part of every assignment.

## Research areas in this panel

One area. We match narrowly: you need to have published on this specific phenomenon, not in biophysics broadly.

**1. Stochastic autocatalytic growth: chemical master equation, branching processes:** Autocatalytic reaction cycles, stochastic Hinshelwood cycle, chemical master equation processes, circulant matrix spectra, transient oscillations toward balanced exponential growth, moment hierarchies for reaction networks, generating-function methods.

If you also work on long-range dispersal, heavy-tailed jump processes or front propagation in range expansions, say so on the form. A closely related area sits in our statistical physics panel and draws on the same methods.

## Methods we expect to find in your own publications

You should be able to point to your own papers demonstrating **at least one** of the following families:

- Chemical master equation and the stochastic Hinshelwood cycle
- Multi-type branching processes and circulant matrix spectra
- Moment hierarchies for reaction networks
- Generating-function methods

## Who we are looking for

**A PhD in biophysics, statistical physics, applied mathematics or a closely related field.** This is a hard requirement. Postdoctoral researchers, research scientists and junior faculty are the strongest fit. Senior PhD students with a strong first-author record are welcome to apply.

**Published work on stochastic growth or reaction-network dynamics specifically.** This is the single most common reason we decline otherwise excellent researchers. Command of the methods is not enough if you have not published on the phenomenon itself.

**A verifiable publication record.** Three to five representative papers with arXiv IDs or DOIs, ideally from the last five years. First author strongly preferred. Every paper you list will be checked against the public record.

**Working proficiency with LaTeX, Python, SymPy and Jupyter.** Some familiarity with an agentic coding extension in VS Code is useful. Gaps there are acceptable if you declare them honestly.

**English at B2 or above**, including written reasoning. A large part of the value you add is how clearly you set out your argument.

## Application steps

1. **Apply and complete the attached form.** Basic information, education, research experience, your method self-attestation, and the area above if you are a fit. Give an arXiv ID or DOI of **your own paper** as proof, with your author position and the methods it demonstrates. A selection without proof is not scored.
2. **We verify your papers and authorship** against the public record.
3. **Then one of two things happens.** Either we onboard you directly, or we invite you to a short live alignment call to agree the area and the assignment with you.
4. A brief **30 to 45 minute assessment** may be added, but only where we need it. Most applicants will not see one.

## Commitment and rate

**10 hours per week**, sustained across an **8 to 10 week** window, starting immediately. Remote and asynchronous with no fixed hours.

**$80 to $110 per hour**, set by depth of subdomain match.

**Published work on the specific phenomenon above, not the adjacent one.** This is the single most common reason we decline otherwise excellent physicists. Working in modified gravity is not enough if your papers are not on torsion, Nieh-Yan or Chern-Simons terms. Command of the numerical methods is not enough if you have not published on the phenomenon itself.

**A verifiable publication record.** Three to five representative papers with arXiv IDs or DOIs, ideally from the last five years. First author strongly preferred. Every paper you list will be checked against the public record.

**Sign-convention discipline.** Work in this area turns on tetrad and spin-connection conventions, and we are looking for people who are precise about them.

**Working proficiency with LaTeX, Python, SymPy and Jupyter.** Some familiarity with an agentic coding extension in VS Code is useful. Gaps here are acceptable if you declare them honestly.

**English at B2 or above**, including written reasoning. A large part of the value you add is how clearly you set out your argument.

## Application steps

1. **Apply and complete the attached form.** Basic information, education, research experience, your method self-attestation, and up to five of the areas above that you are the best fit for. For each area you select, give an arXiv ID or DOI of **your own paper** as proof, with your author position and the methods it demonstrates. A selection without proof is not scored.
    
2. **We verify your papers and authorship** against the public record.
    
3. **Then one of two things happens.** Either we onboard you directly, or we invite you to a short live alignment call to agree the area and the assignment with you.
    
4. A brief **30 to 45 minute assessment** may be added, but only where we need it. Most applicants will not see one.
    

## Commitment and rate

**10 hours per week**, sustained across an **8 to 10 week** window, starting immediately. Remote and asynchronous with no fixed hours.

**$80 to $110 per hour**, set by depth of subdomain match.

## About the work

**CritPt** is a public benchmark of research-level physics challenges, built to test whether frontier AI models can carry out genuine physics research reasoning rather than textbook problem solving. The benchmark paper is **[arXiv:2509.26574](https://arxiv.org/abs/2509.26574)** and we recommend reading it before applying. It will tell you quickly whether this work interests you.

We are engaging physicists to work on research-level physics problems in their own subfield. Depending on where your publication record fits, that can mean creating problems, solving them, reviewing completed work, or auditing it. We agree the specific assignment with you once you are matched to an area.

This is research-grade work rather than volume work. Whatever you produce has to be complete enough for another specialist in your subfield to follow and verify independently, so written reasoning is part of every assignment.

**English at B2 or above**, including written reasoning. A large part of the value you add is how clearly you set out your argument.

## Application steps

1. **Apply and complete the attached form.** Basic information, education, research experience, your method self-attestation, and up to five of the areas above that you are the best fit for. For each area you select, give an arXiv ID or DOI of **your own paper** as proof, with your author position and the methods it demonstrates. A selection without proof is not scored.
2. **We verify your papers and authorship** against the public record.
3. **Then one of two things happens.** Either we onboard you directly, or we invite you to a short live alignment call to agree the area and the assignment with you.

Condensed Matter Physicist (PhD)

Mercor is partnering with a leading AI research lab to build next-generation text-to-speech (TTS) systems capable of producing natural, expressive, and human-like voices. We are seeking **South Africa-based native English speakers with authentic South African accents** to contribute high-quality voice recordings for training and evaluating cutting-edge speech models. This role is open to both experienced voice professionals and newcomers with a naturally clear, expressive voice and a good recording setup — prior voice-acting experience is a plus but not required.

**This is an ongoing opening — we onboard new voices on a rolling basis, so applications are always welcome. The engagement itself is a single recording session of approximately 4 hours. A second session of similar length may follow depending on the client's needs, though this isn't guaranteed.**

**Your voice recordings will be used exclusively for the client's internal CX AI Agent. They will not be sold, licensed, or reused for any other product, dataset, or purpose.**

* * *

### **Key Responsibilities**

- Record high-quality voice samples across diverse scripts (conversational, narrative, instructional, etc.)
    
- Deliver **clear, natural, and expressive speech** with strong control over tone, pacing, and pronunciation
    
- Maintain **consistency in voice, accent, and delivery** across recording sessions
    
- Follow detailed recording guidelines (environment, microphone setup, file formatting)
    
- Perform multiple takes with variation in emotion, emphasis, and style when required
    

### **Requirements**

Securities, Commodities, and Financial Services Sales Agents

## About the work

Mercor is designing a benchmark that measures how well AI agents do real enterprise cyber defense work. Before we build it, we want to hear from people who do that work every day.

This is a short paid research engagement, not a task or data project. You will join two to three one-hour video conversations with the Mercor team over roughly four weeks, scheduled around your availability.

## What we will talk about

- How your work actually happens: the tools you live in, what lands in your queue, where judgment matters and where it does not.
- How your team measures whether a triage, investigation, containment, hunt, detection rule or patch was done well.
- Where AI assistance helps you today, where it gets in the way, and what would make a benchmark of AI on this work credible to you.
- Our draft task taxonomy: what is missing, what is mislabeled, what you would weight differently.

## Who we are looking for

Current or recent hands-on practitioners in enterprise security, for example:

- SOC analysts and SOC leads (tier 2 and above)
- Incident responders and digital forensics investigators
- Detection engineers and threat hunters
- Application security or product security engineers who find and fix vulnerabilities in production code
- Security engineers who have run or been on the receiving end of a red team engagement

Experience with an EDR and SIEM stack (CrowdStrike Falcon, Microsoft Defender and Sentinel, Splunk, SentinelOne, Elastic or similar) is a plus. Security leaders are welcome if you are still close to the work.

## Pay and time

- Paid hourly for interview time as a spot bonus. Sessions are one hour; no prep is expected.
- Two to three sessions in total. Nothing to build, label or submit.
- Remote, US-based.

## Confidentiality

We will ask you to describe patterns, not specific incidents, and to leave out anything confidential about current or former employers or customers. Your input is used only to design the benchmark and is never attributed to you or your employer.

**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 experienced **mechanical engineers** to work directly with a leading AI lab's research and program management teams, improving how frontier AI models reason about real mechanical engineering work.

Your engineering judgment is the substance of this role. You will review the quality of mechanical engineering tasks and model outputs, write the instruction specs and reference solutions that define what "correct" looks like, and help build the evaluations that show whether the model is genuinely improving. We are looking for practicing engineers who have owned real designs, analyses, or systems in industry, not generalists.

This is a W-2 employment position with Cincinnatus LLC, with the opportunity to be placed at a leading AI lab as part of their extended workforce. The initial engagement is 2 to 3 months, with a strong possibility of extension based on performance and project needs. You will be provisioned with client-issued accounts and equipment, and will work inside the client's own tools alongside their research teams.

**Location:** Remote, within the United States.

## 2\. Key Responsibilities

- **Data QA and reviews:** Vet the quality of mechanical engineering tasks and model outputs, spotting incorrect assumptions, missing constraints, unit and tolerance errors, unsafe design choices, and answers that read well but would not pass a design review.
    
- **Instruction specs and reference solutions:** Write clear instruction specs, produce worked reference solutions to mechanical engineering problems, and define new tasks that reflect how engineering work is actually done in practice.
    
- **Benchmarks and domain depth:** Design challenging tasks and evaluation sets across areas such as mechanical design, thermal and fluid systems, structural and stress analysis, manufacturing, and controls, and help build domain-specific tools together with the research team.
    
- **Calibration:** Work with client researchers and specialists in adjacent fields to keep standards consistent, translating tacit engineering judgment into explicit, teachable criteria.
    

## 3\. Core Qualifications

- **Education:** Bachelor's degree or higher in Mechanical Engineering or a closely related engineering discipline.
    
- **Experience:** 5+ years of hands-on professional mechanical engineering experience in industry, for example product design and development, thermal and fluid systems, HVAC, structural or stress analysis, manufacturing engineering, automotive, aerospace, energy, robotics, or medical devices.
    
- **Domain depth:** Genuine ownership of real engineering work, for example designing components or systems, running FEA or CFD analyses, releasing drawings and specifications, or taking products through design reviews, testing, and production.
    
- **Tools and standards:** Working fluency with common engineering tools (for example SolidWorks, CATIA, NX, Creo, AutoCAD, ANSYS, Abaqus, or MATLAB) and familiarity with relevant codes and standards (for example ASME, ASTM, ISO, and GD&T per ASME Y14.5).
    
- **Seniority:** Clear progression toward senior or lead engineering responsibility. A Professional Engineer (PE) license is a plus but not required.
    
- **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 2 to 3 months, with a strong possibility of extension.
    
- Excellent written communication, and the ability to give precise, well-structured written feedback.

The research teams behind the best-known AI models come to Mercor for careful human judgment they can't generate on their own. Your standards and attention become the rubric that frontier AI is graded against.

This is a standing listing for generalists who want AI training and evaluation work, not a specific job opening. It stays open whether or not a matching project is running this week.

New projects start on short notice, so instead of posting and pulling a listing each time, we keep one open per field and draw from it when one begins.

**What the work looks like**

We match generalists in the network to projects like:

- Writing prompts and reference answers on everyday questions that have a right answer, with the context a good response has to account for
    
- Grading model output on general reasoning: whether the answer is correct, whether it follows the instruction actually given, whether it is complete without padding
    
- Flagging where a model is confidently wrong, contradicts itself earlier in the same answer, or answers a question that was not asked
    

Most contracts in this field have paid $40 to $70 an hour, set per project by scope and depth.

**What we're looking for**

- Careful reading and sound judgment, from a professional or academic background in any field
    
- Clear written communication, since most of the work involves explaining your reasoning
    
- Comfort with ambiguous tasks, and willingness to flag unclear instructions
    

**Who this is for**

This pool is for people whose work does not fit neatly into one of our specialist networks, or who work across several of them. If you looked through our other listings and none of them quite described you, this is the one.

No particular credential is required. What matters is that you read carefully and can say precisely why an answer is wrong.

**How it works**

Apply here with your resume and confirm where you work from, then take a short AI interview, about 20 minutes total.

We verify your background and add you to the generalist pool.

When a project needs general reasoning work, we invite matching people from the pool to that specific listing. It names the rate, the hours, and the client, and any hiring decision is made there.

**What to expect**

This listing does not accept or reject candidates, so you will not get a decision on it. We reach out when a project matches your background. Depending on what our clients are running, that can be within a week or several months.

Finishing the domain expert interview and joining every network you qualify for both improve your odds of being matched. You only need to sign up once to be eligible across all of them.

We match data practitioners in the network to projects like:

- Writing an analysis problem from work you actually shipped, with the data, the question, and the constraint, plus the reference answer a model's attempt gets graded against
    
- Grading model-written analysis and pipelines: whether the query answers the question that was asked, whether the join fans out, whether the metric means what the model says it means
    
- Flagging where a model produces a technically valid result that would mislead a decision-maker, given selection effects, leakage, or a metric that does not track the outcome
    

**What we're looking for**

- Professional experience in analytics, data engineering, statistics, or machine learning
    
- Clear written communication, since most of the work involves explaining your reasoning
    
- Comfort with ambiguous tasks, and willingness to flag unclear instructions
    

**What this covers**

This pool spans data analysis, including:

- Business intelligence
    
- Data engineering
    
- Statistics
    
- Machine learning
    

Where you trained matters less than whether you have shipped analyses someone made a decision on.

**How it works**

**What the work looks like**

We match educators in the network to projects like:

- Writing a teaching problem from your own classroom or course, with the level, the common misconception, and the constraint, plus the reference answer a model's attempt gets graded against
    
- Grading model-written explanations and lesson material: whether the explanation meets the learner where they are, whether the worked example is correct, whether the assessment measures what it claims to
    
- Flagging where a model's explanation is accurate and would still confuse a student, given prior knowledge, reading level, or the misconception it fails to address
    

**What we're looking for**

- Professional experience teaching, tutoring, or designing instruction
    
- Clear written communication, since most of the work involves explaining your reasoning
    
- Comfort with ambiguous tasks, and willingness to flag unclear instructions

New projects start on short notice, so instead of posting and pulling a listing each time, we keep one open per field and draw from it when one begins.

**What the work looks like**

We match people in this network to projects like:

- Writing a realistic task from your own work, a document, a model, or a deck, with the starting material and the constraint, plus the reference answer a model's attempt gets graded against

When a project needs mechanical engineering expertise, we invite matching people from the pool to that specific listing. It names the rate, the hours, and the client, and any hiring decision is made there.

**What to expect**

This listing does not accept or reject candidates, so you will not get a decision on it. We reach out when a project matches your background. Depending on what our clients are running, that can be within a week or several months.

Finishing the domain expert interview and joining every network you qualify for both improve your odds of being matched. You only need to sign up once to be eligible across all of them.

Mechanical Engineering Expert

The research teams behind the best-known AI models come to Mercor for mathematical judgment they can't generate on their own. Your standards and expertise become the rubric that frontier AI is graded against.

This is a standing listing for mathematicians who want AI training and evaluation work, not a specific job opening. It stays open whether or not a matching project is running this week.

New projects start on short notice, so instead of posting and pulling a listing each time, we keep one open per field and draw from it when one begins.

**What the work looks like**

We match mathematicians in the network to projects like:

- Writing a problem at research or competition level, with the statement and the intended solution, plus the reference answer a model's attempt gets graded against
    
- Grading model-written proofs: whether each step follows, whether the edge cases are handled, whether an appeal to a known theorem actually satisfies its hypotheses
    
- Flagging where a model reaches a correct answer through an argument that does not prove it
    

Most contracts in this field have paid $40 to $75 an hour, set per project by scope and depth.

**What we're looking for**

- A graduate degree in mathematics or a related field, or an equivalent research or competition background
    
- Clear written communication, since most of the work involves explaining your reasoning
    
- Comfort with ambiguous tasks, and willingness to flag unclear instructions
    

Where you trained matters less than whether you can tell a proof from a convincing sketch, and say precisely where the gap is.
