Clinical Medicine AI Specialist

RLHF and instruction-tuning dataset creation, LLM prompt and response evaluation, named entity recognition, computer vision annotation, content safety labeling, speech-to-text transcription, and red-teaming and safety evaluations. Your specific assignment depends on your skills and profile tier.

Rex focuses on cognition-heavy work: reasoning evaluation, prompt design, domain-specific content generation, and model benchmarking. Instead of high-volume microtask queues, it prioritizes fewer, deeper tasks and pays accordingly, with a stated target of $25-45/hr for expert-level output.

No. Instead of client deliverables, you're given complex scenarios to evaluate: grading the AI's logic, correcting its hallucinations, and supplying expert-level reasoning it doesn't have on its own. The job is closer to teaching than consulting.

Because general knowledge isn't what's being tested. The model already knows the basics; what it needs is expertise on edge cases, the rare, difficult, highly technical judgment calls only a senior professional in the field would make correctly.

Tasks here are scoped to Healthcare, not generic labeling. As a Clinical Medicine AI Specialist, expect to draw on real domain judgment (evaluating outputs, correcting errors, or providing expert reasoning specific to Healthcare) rather than following a one-size-fits-all rubric. If you don't have hands-on Healthcare background, this is likely not the right listing to start with.

Expert is named directly in the listing. If you don't have hands-on experience with this, expect the screening process to test for it directly rather than accepting adjacent experience as a substitute.

This listing is posted at $70–$150/hr, an hourly rate. The range reflects experience level and negotiated terms, not a placeholder, so where you land in it depends on your background and the assessment. Pay can change between when we last checked the listing and when you apply, so confirm the current number on the platform's own application page before committing time.

You'll be taken to Rex's external site to complete your application there. This listing links through a referral, but the process is identical to applying directly; the link just routes you correctly. Create an account on their site and follow their onboarding steps.

This role lists a master's degree as a requirement. In practice, the domain assessment is the real gate. If you can pass it, the degree is usually secondary. However, some platforms verify credentials formally, so list your actual qualifications accurately on your profile.
