Director, Pharmacokinetics & Bioanalysis

About the Role As Director, Pharmacokinetics, you'll shape the scientific and strategic direction of pharmacokinetics, drug metabolism, bioanalysis, and translational PK/PD across our entire portfolio. Working at the intersection of discovery, nonclinical development, clinical development, and regulatory strategy, you'll generate the PK insights that move programs forward — and the decisions that matter most to patients.

You'll design pharmacokinetic strategies tailored to each stage of development, lead internal and external activities, and partner closely with cross-functional teams to guide candidate selection, clinical dose planning, and regulatory submissions — turning scientific rigor into real progress for patients.

Let’s talk about how you’ll make an impact:

Serve as Tarsus’s expert in pharmacokinetics and DMPK, shaping strategy across every program.

Architect and drive PK, DMPK, bioanalytical, and translational PK/PD strategies that carry programs from early discovery all the way through clinical development.

Design, lead, and interpret pharmacokinetic, metabolism, disposition, bioanalytical, and PK/PD nonclinical studies.

Drive human PK projections, dose and regimen selection, and interpretation of emerging clinical data.

Select and lead CROs, laboratories, consultants, and other external partners — assuring study quality, data integrity, and timelines.

Review study protocols, reports, and datasets, identify pharmacokinetic and drug-metabolism risks early, and chart the development strategies.

Author and review the pharmacokinetics, bioanalytical, and related sections of regulatory documents — including INDs, CTAs, investigator brochures, and briefing documents.

Represent Pharmacokinetics on cross-functional project teams and governance forums, translating complex science into clear, actionable recommendations leadership can act on.

Oversee the deployment, standardization, and routine execution of Phoenix Win Nonlin and related modeling platforms for data analysis.
