What the work actually involves
This is a talent network application, not a posting for a defined project. Once you're verified, Mercor routes you to contract work from AI labs that needs clinical judgment: writing diagnostic reasoning tasks grounded in real presentations, grading model responses against standard of care, flagging hallucinated drug interactions or dosing errors, and producing rubrics that let non-clinicians score medical output consistently. Some projects lean toward authoring — you build cases, differentials, and gold-standard answers. Others lean toward evaluation — you read model transcripts and explain, in writing, exactly where the reasoning breaks and what the clinical consequence would be.
The deliverable is almost always prose. Labs pay for the rationale more than the verdict, so a physician who can write two tight paragraphs on why a model's workup order is wrong is worth more than one who can only mark it wrong. Expect your written critiques to be reviewed and, on some programs, calibrated against other physicians in your specialty.
What the platform screens for
- Verified credentials. Medical degree plus a current or recently active license; residency completion and board status are checked against your resume.
- Specialty depth under follow-up. The AI interview asks a clinical question, then pushes on your answer — the screen is measuring whether your reasoning holds up, not whether your first response sounded confident.
- Written clarity. Vague, hedged feedback is the most common reason physicians pass the credential check and still don't get matched.
- Independence. Projects run async with minimal supervision and firm deadlines.
Logistics
Fully remote and asynchronous. Typical commitments run 15–30 hours per week, though scope varies by project and some engagements are shorter bursts. Rates in the $110–250/hr range have been observed across medical programs on Mercor; actual offers depend on specialty scarcity, project complexity, and the client lab — nothing is guaranteed at application time. Matching is rolling, so there may be a gap between approval and your first invitation, and you'll interview again for specific opportunities.
