About Prolific

Prolific is not just another player in the AI space – we are building the biggest pool of quality human data in the world. Over 35,000 AI developers, researchers, and organizations use Prolific to gather data from paid study participants with a wide variety of experiences, knowledge, and skills.

The role

We're looking for Medical Doctors to help train and evaluate cutting‑edge AI models. If you have the necessary experience, we'll send you a quick test to assess your skills and suitability for AI tasks. If successful, you'll be invited to join Prolific as a Domain Expert participant, where you'll get paid to train and evaluate powerful AI models. Researchers looking for your skills tend to pay $80-150 per hour per AI task completed, depending on skills and experience level. You must be prepared to complete paid tasks that require one hour of uninterrupted work, though many are shorter.

What you'll bring

• Verified status as a medical doctor (e.g., current license/registration in good standing; board certification or equivalent where applicable)
• Recent clinical experience and comfort in evaluating clinical reasoning and decision‑making
• Willingness to complete a short skills/eligibility screener to join our Domain Expert pool
• Strong attention to detail and the ability to focus on complex tasks for up to one hour
• A reliable, fast internet connection and access to a computer
• Willingness to self‑declare earnings (participants are self‑employed)
• A PayPal account to receive payments from our clients

What you'll be doing in the role

• Reviewing AI‑generated responses to clinical scenarios and rating them for accuracy, clinical appropriateness, safety, and reasoning quality
• Comparing multiple model answers and selecting/justifying the best response
• Writing improved exemplars, rationales, or structured feedback to help models learn where they fall short
