Medical Expert

About the Role

Mercor is partnering with a leading AI lab to train frontier models on high-quality healthcare reasoning data. We're expanding our Medical Expert network. As a Medical Expert, you'll design realistic clinical scenarios, evaluate model outputs against evidence-based standards, and help shape how the next generation of AI reasons about patient care.

If your specialty has its own dedicated listing on Mercor (Internal Medicine, Emergency Medicine, Psychiatry, Hematology/Oncology, Radiology, Cardiology), please apply through that listing instead — you'll see the rate band that actually applies to you. Use this listing if your specialty is not yet listed (e.g., Family Medicine, Pediatrics, Anesthesiology, Surgery, ENT, PMR/Pain, Occupational Medicine, etc.).

What You'll Do

• Design clinically realistic prompts and scenarios drawn from your specialty (diagnostic reasoning, treatment planning, risk stratification, guideline concordance)

• Write "golden" reference responses at attending-level quality

• Grade AI-generated responses against structured rubrics

• Provide written feedback the research team uses to improve model behavior

• Participate in onboarding office hours and specialty calibration sessions
