Mercor is a San Francisco talent marketplace that places domain experts on contract work for frontier AI labs. The labs need doctors, lawyers, bankers, engineers, scientists and writers to produce and grade the material their models learn from. Mercor recruits those experts, screens them once, and matches them to projects.
Most listings never name the client. Your contract is with Mercor and the lab stays anonymous. What the listings do publish is the rate, and Mercor rates sit at the top of this feed: expert contracts regularly post above $100 an hour, and its contractor network pays out weekly for hours logged.
The work is remote and asynchronous. You are matched based on your profile and interview score rather than applying into a queue, so the screening step carries more weight here than on any other marketplace in this feed.

Computed from Mercor’s own published rates on the live feed, not from survey estimates.
Mercor publishes an hourly rate on nearly every listing, which is not the norm in this market. Rates track scarcity: generalist evaluation work starts near the bottom of the range, and expert contracts in medicine, law, finance and senior engineering post several multiples higher. Payouts run weekly.
Mercor hires for depth in a profession, not for AI skills. The busiest verticals in its listings: physicians and medical specialists, attorneys, finance professionals, senior software engineers, and PhDs across the sciences. Generalist writing and evaluation roles exist too, at lower rates.
The pattern in who gets matched: years of real practice beat credentials alone, and credentials beat enthusiasm. A practising radiologist or a staff engineer clears the bar faster than a strong generalist, because scarce judgment is the product Mercor sells.
Mercor screens once, upfront, with a roughly 20-minute AI interview. It asks about your background, then pushes into how you reason inside your own field. The recording and transcript are scored and attached to your profile, and every project match reads from that score.
Mercor caps retakes at three, shared across every application, and evaluates only your most recent attempt, so a rushed retake overwrites a good score. Take the free practice interview first: it is unlimited and never shared with companies. Candidates fail by narrating their resume instead of explaining their thinking. The interview rewards people who can walk through a decision the way they would teach it: what they considered, what they ruled out, and why.
Further reading
Skillora runs the same format: a domain interview with an AI interviewer, followed by feedback on how you explained your reasoning. Take it as many times as you want before the one that counts.
Start a free practice interviewYes. Mercor is a venture-backed San Francisco company with a contractor network in the tens of thousands, paying out weekly across medicine, law, finance and engineering. The catch is selectivity, not legitimacy: expert roles filter hard on real credentials and on the AI interview, and most applicants never get matched. Treat the screen as the actual hiring bar.
By role, and the listings above show the live numbers. Generalist evaluation work posts in the $15 to $30 an hour range. Expert contracts in medicine, law, finance and senior software engineering commonly post $70 to $150 an hour, and some specialist roles go higher. Payment is weekly, for hours logged against your project.
It is about 20 minutes with an AI interviewer, recorded. Expect background questions first, then role-specific reasoning: a clinical scenario for physicians, a design discussion for engineers, a deal or accounting question for finance. Your answers are transcribed and scored, and that score drives which projects you are matched to. You can retake it, but prepare before the first attempt rather than after.
No. Mercor exists to move expertise into models that the models do not have, so it hires practitioners: the lawyer, the cardiologist, the staff engineer. Software engineering roles are the closest to an exception because the work product is code. Everyone else is hired for domain judgment and clear written reasoning.
Contractually, Mercor. The end client is typically a frontier AI lab that stays unnamed on the listing and behind an NDA after you join. That structure is normal for this market: the labs buy expert data through marketplaces precisely so they do not run contractor operations themselves.
Matching is demand-driven: some contributors start within days, others wait weeks, and many applicants are never matched. A complete profile and a strong interview score are the two levers you control. If your specialty is quiet, listings in adjacent categories, evaluation work, writing-heavy roles, are where matched contributors usually start.
