Senior Scientist, Pharmacokinetics

Senior Scientist, Transporters Science Our company is a global health care leader with a diversified portfolio of prescription medicines, vaccines, and animal health products. The Department of PDMB (Pharmacokinetics, Dynamics, Metabolism, and Bioanalytics) within our company Research Laboratories in West Point, Pennsylvania, is seeking a highly motivated and scientifically accomplished Senior Scientist to join the Transporter Science Group. The Transporter Science Group serves as a center of excellence for the design, execution, and integration of transporter-related in vitro and preclinical studies supporting our company portfolio across all stages of drug discovery and development. The group also advances ADME-transporter science through the development and application of innovative in vitro and preclinical models, as well as translational strategies that enhance our ability to quantitatively predict the role of transporters in ADME, drug-drug interactions (DDIs), efficacy, and toxicity across a broad range of therapeutic areas and modalities. The successful candidate will possess a strong understanding of drug transporters and their influence on drug disposition and DDIs, along with a demonstrated commitment to generating high-quality in vitro transporter data in support of project teams across therapeutic areas. This individual should have strong independent bench-level in vitro expertise, the ability to contribute to complex scientific initiatives, and excellent written and verbal communication skills. The ability to collaborate effectively in a highly interactive team environment is essential. This position offers the opportunity to collaborate with scientists across the DMPK network and with colleagues in Medicinal Chemistry, Biology, Data Science, Clinical Research, and Toxicology to advance discovery and development programs. The successful candidate will also contribute to the evolution of the scientific strategy by developing and implementing novel tools and emerging technologies that improve the translation of in vitro data to quantitatively predict transporter-mediated drug disposition, DDIs, toxicity, and enzyme-transporter interplay.
