Job description
J.S. Held is seeking a Principal Epidemiologist to join our Health Sciences practice.

Project Leadership & Delivery

Design and oversee study protocols, including exposure assessment, outcome definition, and causal inference strategies
Ensure rigorous QA/QC processes across all analyses and deliverables
Manage project teams, timelines, budgets, and client expectations in a consulting environment
Methods & Analytics
Apply advanced epidemiologic methodologies, including:

Contribute to thought leadership, including publications, conference presentations, and client briefings
Support go-to-market initiatives and enhance J.S. Held’s visibility in expert services and advisory markets
Help shape and expand the firm’s epidemiology and health risk capabilities globally
Required
Doctoral degree (PhD, ScD, or DrPH) in Epidemiology from a regionally accredited, research-intensive (non-profit) university
Approximately 15+ years of post-graduate, client-facing consulting experience, delivering epidemiological analyses within litigation, regulatory, or risk management environments
Demonstrated seller–doer track record, including a portable book of business and consistent delivery against annual revenue and origination targets
Proven experience serving as an expert witness, including authorship of expert reports and participation in depositions and/or courtroom testimony, with the ability to perform effectively under cross-examination
Advanced expertise in epidemiologic methods and strong command of statistical tools (e.g., R, Python, SAS, SPSS, or Stata), with the ability to lead technical teams and guide analytical workstreams
Exceptional written and verbal communication skills, with the ability to clearly present complex methodologies and findings to attorneys, regulators, and senior business leaders
Preferred
Familiarity with U.S. litigation processes, including experience supporting mass torts, class actions, or regulatory enforcement matters
