Principal Scientist Drug Metabolism And Pharmacokinetics

The Pharmacokinetics, Dynamics, Metabolism, and Bioanalytics (PDMB) function of our Research & Development Division in West Point, Pennsylvania, is seeking a dynamic and collaborative scientist for the Drug Metabolism and Pharmacokinetics (DMPK) group. The Principal Scientist will be a key contributor to multi-disciplinary drug development and discovery efforts providing an integrated understanding of DMPK properties, pharmacokinetics/pharmacodynamics (PK/PD), and drug interaction (DDI) risk of novel therapeutics.

The key responsibilities will be to work within teams of highly collaborative, cross-functional scientists to contribute to the clinical development and discovery of therapeutics across various modalities. The Principal Scientist will guide the design and interpretation of in silico, in vitro, and in vivo analyses to support the development and discovery of therapeutics with the desired DMPK profile. They will assess program risks including DDI, metabolism and translation to guide clinical development teams.

They will author source reports and regulatory documents in support of filings. They will independently evaluate and predict potential program risks, while implementing appropriate strategies to address liabilities and ensure efficient program progression and decision making.

The ideal candidate must be able to work collaboratively in a fast-paced environment, drive scientific development and innovation, and have excellent interpersonal and communication skills. Experience supporting both small molecule and biologics (e.g. antibodies and drug conjugates) programs is desired.
