Overview
Mercor needs practicing scientists and engineers to stress-test AI assistants on work that mirrors their own day job. You draft a short request the way a real user would, then stay in the conversation across several turns, correcting the model and answering its questions as it works. At the end you score both the interaction and the deliverable against the standard your field expects. Expect roughly 10 hours a week on a flexible remote schedule, with work split between writing prompts, LLM evaluation, and short written feedback.
What You'll Do7
- Draft brief, realistic task requests in your discipline, worded the way an actual practitioner would type them
- Guide the AI assistant through multi-turn work by clarifying scope, supplying missing context, and flagging mistakes
- Challenge answers that drift from accepted practice in chemistry, physics, or engineering
- Score the final deliverable and the conversation itself using the rubric the project provides
- Write concise notes on what the assistant handled well and where it failed
- Keep your scenarios grounded in genuine professional work rather than textbook puzzles
- Log around 10 hours of evaluation work each week on a schedule you set
Requirements7
- A degree in a physical science or engineering discipline
- 3 or more years of professional experience in that field
- Working background as a chemist, physicist, or a civil, mechanical, electrical, or chemical engineer
- Some hands-on use of AI assistants in your own work
- Clear, precise English writing for the feedback notes and scores
- Ability to judge technical output against real industry standards
- Access to the assistant from your country of residence
Who Should Apply
Practicing chemists, physicists, and engineers with at least three years on the job who already use AI tools and can spot when a model gets the technical details wrong. If you can write a realistic work request and explain your scoring in plain English, this fits.
Salary Insight
$84 per hour is well above typical freelance rates for AI evaluation and data annotation work, which usually land in the low double digits to low thirties. The premium reflects the degree plus 3 years of professional experience the project requires.
Application tip
Name your exact discipline and years of experience in the first line of your profile, then describe one real task from your job that you could turn into an evaluation scenario. Mentioning which AI assistants you use and how often strengthens the match.
