Mathematics AI Trainer, AI Model Training
$40 - $125 per hourTemporary
Crucial Recruiting
Mathematics AI Trainer (Remote)100% Remote | Part-Time or Full-Time | Freelance Contract | $40 to $125 per hour Work on your own schedule. Get paid for what you already know. A leading AI research company that works with large AI companies is seeking experienced mathematicians to work as remote AI trainers and evaluate how frontier AI models handle real technical work: analyzing test, measurement or process data, sizing and verifying a design, designing and reading out an experiment, interpreting a simulation and writing the technical report. You bring the judgment you have built catching the unit error in a test file and the assumption that does not hold at the boundary. This is project-based, fully remote work you can do alongside a current job, including evenings and weekends. What the Work Involves
- Design realistic tasks from your own work, such as a calculation package with stated assumptions and checks, a test plan and data analysis, a failure or deviation investigation, a design trade study or an experimental protocol
- Author the supporting files a scientist or engineer would use: test data, drawings or schematics, specifications, simulation outputs, lab records, reports
- Run those tasks through frontier AI models and grade the calculation, analysis, design review or report they produce
- Compare two model outputs on the same task and document where each fell short
- Write grading rubrics covering the right assumptions, method, magnitudes, units and failure modes
- On coding projects, author and verify tasks in Python or similar at the command line
- Applied mathematics and modeling
- Statistics and probability
- Numerical analysis and scientific computing
- Optimization and operations research
- Pure mathematics with applied practice
- Mathematical finance or actuarial work
- 2+ years of applied experience in mathematics, statistics or a closely related field, outside of undergraduate study, preferred
- Coding or scientific computing (Python or similar) is a strong plus and is required on some projects
- Hands-on with real data and the tools of your field: modeling and analysis in Python, R, MATLAB or similar, and writing work up as clear technical reports
- Comfortable with experiment design, measurement error and uncertainty, and common statistical traps; the assessment leans on this
- Working understanding of adjacent areas, enough to judge work outside your own specialty
- Hands-on practitioner: you currently do, or recently did, the work yourself as an individual contributor, not solely as a manager
- Strong written English; you can explain clearly why a result is wrong, not only that it is
- Familiar with AI tools such as Claude or ChatGPT, with the judgment to tell a well-reasoned answer from a plausible-sounding wrong one
- Comfortable working independently, following detailed written instructions and incorporating feedback
- Pay: $40 to $125 per hour, depending on project and expertise. Paid via PayPal on a regular schedule. You are paid for every step you complete
- Hours: Minimum 10 hours per week with no maximum. Many projects prioritize 30 to 40 hours per week, and full-time hours are available. Multi-day task timers let you spread work across days
- Location: Remote. Must be based in the United States, Canada, or the UK
- Tools: Access to the AI models you will evaluate is provided; no personal subscription needed
- Apply here with your resume
- We review your background against the role
- If it's a fit, we send you a link to take the client's skills assessment. It's unpaid, takes about 2 to 4 hours and tests domain judgment and careful reading. The assessment must be entirely your own work; AI-assisted submissions are detected and rejected
- If you pass, you complete onboarding and a short training project, then propose and build tasks from your own professional experience, with expert review and written feedback at each stage
