Physics Expert, AI Trainer

About this role

Fully remote, project-based work checking how well frontier AI does real physics: modeling, simulation, and measurement. You write tasks based on your own experience and grade where the model gets it wrong. $40 to $125 USD an hour, at least 10 hours a week, as an independent contractor. For physicists working in research or industry in the US, UK, Ireland, Canada, or Australia. About the role AI models can walk through physics fluently and still set a problem up wrong. This role puts your experience to work finding out where. You turn problems from your own work into realistic tasks, run them through frontier models, and judge the answers the way you would check a colleague's calculation. Some projects involve writing code. You set your own schedule, and the work rewards careful writing as much as expertise. Responsibilities Build realistic tasks out of problems from your own physics work, along with the material needed to solve them Give those tasks to frontier AI models and judge the results against the standard of your profession Weigh paired model answers against each other and explain which one holds up Write grading rubrics for your tasks and set out your reasoning in writing Review and improve tasks written by other experts Requirements - Based in the United States, United Kingdom, Ireland, Canada, or Australia - Bachelor's degree or higher, completed or in progress - 2+ years of applied physics experience preferred - Available at least 10 hours per week - PayPal account for payment - Willing to work without LLM assistance where the project does not permit it - Use one email address to sign up, take the assessment, and get paid Ideal qualifications Degree in physics or a related field, completed or in progress Hands-on work with models, simulations, or measurement data Full professional or native-level written English Based in the United States, United Kingdom, Ireland, Canada, or Australia Nice to have Programming experience, for example in Python Have used Claude or ChatGPT in your professional work Pay $40 to $125 USD an hour. The rate varies with your expertise, education, and experience. Minimum 10 hours a week with no weekly maximum; full-time hours are available. Independent contractor, fully remote. Payment runs through PayPal, so you need a PayPal account. As an independent contractor, you handle your own taxes. Getting on: a skills assessment that takes most people four to six hours. You are paid $240 for it if you pass, and you get one attempt, so take your time and do your best work. Work produced with AI tools is rejected. After you pass: onboarding and a short training project, then you propose a task from your own practice, build it, and run it against frontier models. Each stage is reviewed before you move on, and you are paid for the work you complete.
