“This is technically right…
but clinically wrong.”
That’s the gap you’d be paid to close.
AI companies need licensed physicians to review clinical outputs and flag what the model got wrong. No AI background required — your clinical reasoning is the qualification.
What ACJ is
Applied Clinical Judgement is a referral service run by Sean Key. ACJ identifies AI training roles and refers qualified candidates to Mercor and Micro1. If you’re placed, ACJ earns a referral fee from the platform. This doesn’t affect your pay or application in any way.
What Mercor and Micro1 are
Mercor and Micro1 are AI staffing platforms that connect subject-matter experts with AI companies needing training data. They are not employers — work is freelance contract. You are paid as an independent contractor, typically weekly via Stripe or Wise.
How we support your application
When you apply we’ll ask for your name or email — either is fine. If you leave your email, we can support you through the application process. Strong candidates can also request a vouch: a brief 15-minute call with Sean, after which ACJ can add a personal note to your Mercor application.
What happens after you apply
You will complete a profile and an AI interview on the platform. Mercor and Micro1 then match you to relevant projects. There’s no guarantee of work — matching depends on your background and current project availability. Rates shown are indicative.
Adar Hiremath is the co-founder and CTO of Mercor — the platform you will register on. This short video walks through exactly what the application process looks like: uploading your CV, the AI interview, how projects are matched to your profile, and how you track your earnings. Worth watching before you apply.
Rates quoted in this video are platform-wide maximums across all domains. Physician roles on this page pay $100–$250 per hour depending on the role and your profile.
Angela is a medical expert currently working through Mercor. She trained and qualified in the US, where medical school debt of $200,000–$300,000 is common for physicians. Her financial situation is her own — what matters here is how she describes the work itself: the alignment with her medical training, the analytical nature of the tasks, and what it’s like to apply clinical expertise outside the clinic.
