Epidemiologist — Patient Population Sizing
Listed on Mercor as “Epidemiologist - Patient Population Sizing”
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.

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
