About The Position

As Director, Translational Science/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. Driving Innovation, Inside and Out: Partner with our Innovation Lab and Business Development team to evaluate new assets, surfacing the risks and opportunities that shape what we pursue next.
