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 (Epidemiologist - Patient Population Sizing) reflects the rate band and the expertise required, not the day-to-day work.

How Mercor picks people

Upload your CV and answer the role's written questions.
Do a video interview with Mercor's AI interviewer. Most take about 20 minutes, in English unless the role says otherwise.
Some roles add a skills test. A test you pass once counts for similar roles.
The project team reviews your results and sends offers to the people it picks.

Before you start

Take Mercor's free practice interview first. It does not count toward any application.
Use Chrome on a computer with a camera and microphone, in a quiet room.
You can retake an official interview up to 3 times, but hiring teams see how many times you retook it.

Not every applicant gets an offer. Prepare well for the interview.

Original posting from Mercor

Mercor is partnering with a biotech and pharma research team on expert human-evaluation work - creating and critiquing rubrics that analyze commercial drugs and drug-development programs. We're seeking an epidemiologist for a paid pilot, with the potential to continue as the work scales.

Responsibilities

Create and critique rubrics that analyze commercial drugs and drug-development programs

Size the patient population for a given drug or indication (prevalence, incidence, diagnosed → treated → addressable)

Judge whether a patient-population estimate is sound and well-sourced, and flag over- or under-counting

Apply this across the pilot's set of drugs and indications

Requirements

US-based epidemiologist

Familiarity with biotech/pharma development programs

Experience turning real-world data (claims, EHR, registries) into patient funnels

5+ years practising epidemiology (graduate degree in epidemiology, biostatistics, or public health)

Engagement Details

Duration: Approximately 10-20 hours over a 1-2 week pilot

Remote - US-based

Why Participate

Help improve expert AI evaluation of drugs and drug-development programs

Recurring engagement for strong contributors
