This is a non-clinical role — no direct patient care, and no responsibility for live diagnosis.

This is a shared expert pool. After onboarding you may be matched to any of several concurrent workstreams based on your subspecialty, availability, and interest. You are not committing to a single project, and you may move between streams as priorities shift.

Work varies by workstream and may include:

Task length varies by stream, from roughly 10 minutes for structured annotation up to an hour for full case authoring. You will get a specific throughput target for whichever stream you are matched to.

Dermatology is one of the most image-dependent specialties in medicine, and one where model performance still varies sharply across skin tones and rarer presentations. The reference standard these systems get graded against is written by dermatologists — here you would be writing it.

Contract and Payment Terms

• You will be engaged as an independent contractor.
• This is a fully remote role that can be completed on your own schedule.
• Projects can be extended, shortened, or concluded early depending on needs and performance.
• Your work at Mercor will not involve access to confidential or proprietary information from any employer, client, or institution.

• Case interpretation with written reasoning — working through clinical cases that pair dermatological images with patient history, recording your diagnostic reasoning step by step rather than only the final impression.
• Structured image annotation — describing lesions against a defined schema: morphology, colour, configuration, distribution, and body site.
• Differential and severity assessment — recording a ranked differential with your reasoning, and grading severity or progression from images.
• Output review — judging AI-generated dermatological assessments against clinical standards, flagging hallucinated findings, missed findings, and unsupported certainty.
• Grading criteria and guideline authoring — defining what separates an excellent assessment from a merely acceptable one, so judgment can be applied consistently at scale.
• Difficult-case writing — constructing cases that probe the limits of current model reasoning, including presentations that vary across skin tones.
