As a Scientist, Drug Metabolism at Gilead you will support PK and PK/PD modeling across discovery and development, with an emphasis on large-molecule therapeutics, including biologics, ADCs, and multispecific/T-cell engagers. The role will apply mechanistic and translational modeling to support study design, human PK and dose predictions, and program decision-making.

This is a site-based position at our Foster City campus.

Essential Duties and Job Responsibilities

• Provide PK and PK/PD modeling support across discovery and development, with particular emphasis on large molecules, including biologics, ADCs, and multispecific/T-cell engager therapeutics. Contribute to the design and interpretation of nonclinical PK, toxicology, and pharmacology studies.
• Contribute to quantitative DMPK strategies by working with interdisciplinary project teams to apply modeling approaches to program questions and decision-making.
• Develop and apply mechanistic PK/PD models to address translational questions, support dose selection, and predict first-in-human exposures, including approaches relevant to large-molecule PK, TMDD, target engagement, and nonlinear disposition.
• Develop and apply modeling and simulation workflows to support nonclinical study design and data interpretation, incorporating AI-based approaches where appropriate.
• Analyze and communicate modeling results and recommendations to project teams, collaborators, and management.
• Work with project teams, line management, and CROs to support high-quality and timely delivery of analyses and documents for regulatory submissions.
• Contribute quantitative modeling expertise to business development and licensing evaluations.

Requirements:

• Ph.D. with 0+ years of post-graduate industry experience in PK, drug metabolism, pharmaceutics, or a related field, with a focus on quantitative PK/PD modeling OR
• Masters with 4+ years of post-graduate industry experience in PK, drug metabolism, pharmaceutics, or a related field, with a focus on quantitative PK/PD modeling
• Strong foundation in PK/PD principles and mathematical modeling, with knowledge of large-molecule disposition, TMDD, target engagement, and translational PK.
• Experience with mechanistic PK/PD and multi-compartmental modeling and proficiency in Phoenix/WinNonlin, MATLAB/SimBiology, R, GastroPlus, or equivalent tools.
• Ability to design and interpret modeling workflows, draw conclusions from quantitative analyses, and clearly communicate results to diverse audiences.
• Experience applying AI to model building and/or automation of modeling workflows.
• Intellectual curiosity and interest in advances in biologics DMPK and quantitative modeling, with evidence of scientific contributions through publications, presentations, and/or professional activities

Preferred:

• Degree concentration in engineering or pharmacology
• Experience with large-molecule therapeutics, including biologics, ADCs, multispecific antibodies/T-cell engagers, or other protein therapeutics

People Leader Accountabilities:

• Create Inclusion - knowing the business value of diverse teams, modeling inclusion, and embedding the value of diversity in the way they manage their teams.
