Medical Expert - review AI outputs in your specialty

The research teams behind the best-known AI models come to Mercor for medical judgment they can't generate on their own. Your standards and expertise become the rubric that frontier AI is graded against.

This is a standing listing for clinicians and health professionals who want AI training and evaluation work, not a specific job opening. It stays open whether or not a matching project is running this week.

New projects start on short notice, so instead of posting and pulling a listing each time, we keep one open per field and draw from it when one begins.

What the work looks like

We match health professionals in the network to projects like:

• Writing a case from your own practice, with the presentation, the workup, and the constraints, plus the reference answer a model's attempt gets graded against

• Grading model output on clinical reasoning: whether the differential is ordered sensibly, whether the guideline actually applies to this patient, whether the plan is safe to carry out

• Flagging where a recommendation is defensible in a textbook and wrong in front of the patient, given comorbidities, access, or what the care setting can deliver

Rates vary widely by profession within this field. Listings across it have posted from $60 to $180 an hour, set per project by scope and depth.

What we're looking for

• A clinical credential and professional experience in a health profession

• Clear written communication, since most of the work involves explaining your reasoning

• Comfort with ambiguous tasks, and willingness to flag unclear instructions

What this covers

This pool spans the medical field, including:

• Internal medicine, surgical specialties, and diagnostic medicine

• Mental health, including psychiatry and clinical psychology

• Nursing; dentistry; pharmacy

• Medical technology and laboratory science

• Public health and epidemiology

• Healthcare administration; medical writing

This pool is broader than physicians. If you carry clinical judgment in any health profession, it belongs here.

How it works

Apply here with your resume and confirm where you work from, then take a short AI interview, about 20 minutes total.

We verify your credentials and background and add you to the medicine pool.

When a project needs your profession or specialty, we invite matching people from the pool to that specific listing. It names the rate, the hours, and the client, and any hiring decision is made there.

What to expect

This listing does not accept or reject candidates, so you will not get a decision on it. We reach out when a project matches your background. Depending on what our clients are running, that can be within a week or several months.

Finishing the domain expert interview and joining every network you qualify for both improve your odds of being matched. You only need to sign up once to be eligible across all of them.
