Job description

This role is for one of our clients

Compensation: $150-$175 per hour

1. Overview

We are seeking an experienced Epidemiologist to support an expert evaluation project focused on commercial drugs and pharmaceutical development programs.

In this role, you will apply your epidemiological expertise to assess how accurately patient populations are defined and estimated for specific drugs and clinical indications. You will develop and critique evaluation criteria, assess patient-population estimates, and provide rigorous feedback on whether the underlying assumptions, methodology, and data sources reflect sound epidemiological practice.

This opportunity is particularly suited to professionals with hands‑on experience working with real-world healthcare data and patient‑funnel analysis within pharmaceutical, biotechnology, healthcare, or research environments.

2. Key Responsibilities

• Develop and critique structured evaluation rubrics for analyzing commercial drugs and drug‑development programs.
• Estimate and assess patient populations associated with specific drugs and clinical indications.
• Analyze patient funnels across stages such as:
• Disease prevalence and incidence
• Diagnosed populations
• Treated populations
• Eligible populations
• Addressable patient populations
• Evaluate whether patient‑population estimates are methodologically sound, appropriately sourced, and supported by credible evidence.
• Identify potential over‑counting, under‑counting, selection bias, or inappropriate assumptions within population estimates.
• Review methodologies used to translate epidemiological data into commercially relevant patient populations.
• Apply consistent epidemiological judgment across a range of drugs and therapeutic indications.
• Provide clear, evidence‑based written feedback explaining the rationale behind conclusions and evaluations.

3. Required Qualifications

• 5+ years of professional experience in epidemiology or a closely related discipline.
• Graduate degree in Epidemiology, Biostatistics, Public Health, or a related quantitative health‑science field.
• US‑based professional experience.
• Familiarity with biotechnology and pharmaceutical development programs.
• Hands‑on experience using real‑world healthcare data, including:
• Claims data
• Electronic health records (EHR)
• Patient registries
• Epidemiological databases
• Other population‑level healthcare datasets
• Demonstrated ability to translate real‑world data into patient funnels and population estimates.
• Strong understanding of prevalence, incidence, diagnosis rates, treatment patterns, and patient eligibility.
• Excellent analytical and written communication skills.
• Ability to clearly explain methodological assumptions, data limitations, and the reasoning behind population estimates.

4. Engagement Details

• Role: Epidemiologist — Patient Population Sizing
• Work Arrangement: Fully Remote
• Location: United States
• Engagement Type: Independent Contractor
• Pilot Duration: Approximately 10–20 hours over a 1–2 week period
• Projects may be extended based on project requirements and contributor performance.
