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 WinNonlin and related modeling platforms for data analysis.

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.

• Scout and bring in new methods, AI technologies, and external capabilities that sharpen pharmacokinetic prediction, accelerate development, and improve the quality of every program decision.

• Cultivate strong scientific relationships, inside Tarsus and out, that push development forward.

Factors for Success:

• Decision Making - Demonstrates strong decision-making by applying structured analysis to complex challenges, balancing competing priorities and long-term impacts while engaging stakeholders and driving solutions aligned with organizational goals.

• Collaboration and Team Building - Promotes collaboration by aligning diverse teams around shared goals, fostering healthy debate to advance outcomes, and building strong networks that strengthen organizational effectiveness and cross-team learning.

• Outcome Driven - Demonstrates strong outcomes focus by aligning teams around shared priorities, proactively addressing risks and dependencies, and driving cross-functional accountability to sustain progress and deliver results.

• Empowering Others - Fosters empowerment by aligning authority with accountability, developing leaders’ decision-making capability, and creating systems that support performance and growth.

• Emotional Intelligence - Foster trust and psychological safety, navigating complex interpersonal dynamics with compassion and accountability, and adapting leadership style to support others while maintaining composure under pressure.

Minimum Requirements/Qualifications:

• An advanced degree in pharmacokinetics, pharmaceutical sciences, pharmacology, chemistry, biochemistry, biomedical engineering, or a related scientific field and a minimum of 10 years relevant experience; candidates with a bachelor’s or master’s degree and equivalent relevant experience (> 15 yrs) are also encouraged to apply.

• Substantial industry experience in pharmacokinetics, DMPK, bioanalysis, clinical pharmacology, pharmacometrics, or a related drug-development discipline.

• A track record of driving impact across drug discovery, nonclinical development, and/or clinical development programs.

• Deep, broad command of pharmacokinetics, drug metabolism, bioanalysis, and how PK/PD data can sharpen development decisions.

• Experience working with external research organizations, laboratories, or other development partners.

• Experience preparing, reviewing, or contributing to scientific and regulatory documentation.

• A gift for translating complex scientific data into clear, actionable recommendations for cross-functional teams and leaders.

• Strong written, verbal, organizational, and project-management skills.

• A collaborative, proactive scientist who thrives in a fast-paced, matrixed environment.

• An entrepreneurial mindset and an owner’s sense of accountability.

Preferred Qualifications:

• Experience using Phoenix WinNonlin for modeling and simulation, including PK/PD or other quantitative approaches.

• Experience supporting regulatory interactions or submissions.

• Experience building scientific capabilities, mentoring the next generation of talent, or leading internal/external partnerships.
