In short

You would help train AI models on medical reasoning by checking which of two answers to the same clinical question is better. This may suit you if you hold an advanced medical or research degree and have real work experience, because your judgment about diagnosis and patient care is the heart of the job.

What you will do

  • Compare two AI answers to the same prompt and choose the better one.
  • Read the provided files and the model's reasoning to guide your choice.
  • Explain in writing why one answer is stronger, looking at medical accuracy, safety, and quality of reasoning.
  • Give written feedback that the research team uses to improve how the models behave.
  • Join onboarding and specialty calibration sessions.

What you need to apply

  • A PHD, or an equivalent advanced clinical or biomedical degree, or equivalent professional experience.
  • At least 2 years of professional experience in clinical practice, medical research, or a biomedical specialty.
  • Confidence applying current clinical guidelines and evidence-based medicine.
  • Excellent written communication and a strong eye for detail.

Who can apply

Anyone can apply from anywhere in the world, since no country restriction is stated. The work is remote and paid on a freelance contract.

My tip

The pay is 150 USD per hour and the workload is 10, 20 hours per week, so check that this fits your schedule before you apply. Reviews run on a rolling basis and the role starts immediately, so we suggest sending your application early with your PHD and your 2+ years of experience clearly stated.
