STEM Expert (Physics, Chemistry, Mathematics, Biology) - review AI outputs in your specialty
Listed on Mercor as “STEM Expert (Physics, Chemistry, Mathematics, Biology)”
What this actually is
You design problems that stump current AI models, evaluate AI reasoning against the correct answer, write rubrics, and provide expert feedback. Often the highest-paid category because the expertise pool is small. The platform title (STEM Expert (Physics, Chemistry, Mathematics, Biology)) reflects the rate band and the expertise required, not the day-to-day work.
