What this actually is
You design problems that stump current AI models, evaluate AI reasoning against the correct answer, write rubrics, and provide expert feedback. Often the highest-paid category because the expertise pool is small. The platform title (Cardiac Electrophysiologist) reflects the rate band and the expertise required, not the day-to-day work.
How micro1 picks people
- Apply to the role, then do an interview with micro1's AI recruiter. It takes 20 to 40 minutes.
- Some roles add a short skills test after the interview.
- If you pass, micro1 asks you to finish your profile and verify your ID. You then join its certified pool and can apply to its other open roles.
Before you start
- Plan for 40 minutes in a quiet place.
- Have your CV and two or three examples of your own work in this field ready to talk about.
Not every applicant gets an offer. Prepare well for the interview.
