Pioneering Medicines: Associate Director / Director DMPK Project Lead

What if... We could harness the power of Flagship’s scientific platforms and create novel treatment options that benefit more patients, sooner? About Pioneering Medicines: Pioneering Medicines, Flagship Pioneering’s in-house drug development unit, is dedicated to conceiving and developing a broad portfolio of life-changing treatments for patients built from Flagship’s innovative platforms. Harnessing the drug development expertise of its team together with the power of Flagship's multiple scientific platforms, Pioneering Medicines explores and identifies new product concepts which are then advanced jointly with Flagship’s bioplatform companies. Within Flagship’s Innovation Supply Chain partnerships, Pioneering Medicines works with external collaborators to apply its unique approach to partners’ R&D priorities. These partnerships are highly co-creative strategic alliances that accelerate therapeutic innovation by bringing together partners spanning the full spectrum of drug discovery, development, and production. This role can be remote or at our Cambridge, MA site. If over 30 miles from our Cambridge site a travel cadence will be set at time of offer (about monthly). Position Summary: We are seeking a highly motivated and experienced DMPK project representative to join our growing team. This leadership role will provide scientific and strategic DMPK guidance across our biologics portfolio, supporting a wide range of therapeutic modalities including monoclonal antibodies, bispecifics, fusion proteins, and innovative targeted-delivery platforms. The ideal candidate brings deep expertise in DMPK, bioanalysis (BA), and immunogenicity science, with a proven ability to influence discovery and development strategies for biologics. You will collaborate closely with multi-disciplinary teams to optimize candidate selection, design and execute preclinical studies, and ensure regulatory readiness. This is a high-impact role requiring strong analytical thinking, scientific rigor, and exceptional communication skills. Key Responsibilities: Serve as the DMPK representative on cross-functional discovery teams to guide PK, BA and immunogenicity strategies that support project decisions and milestones. Design and lead in vitro and in vivo PK/BA/Immunogenicity studies to characterize biologics properties and support candidate progression. Interpret study data, identify issues, and proactively troubleshoot technical challenges. Collaborate with internal and external stakeholders to plan and execute DMPK deliverables with high quality and efficiency. Collaborate with PK/PD modelers to establish PK/PD correlations and guide preclinical study design. Contribute to the selection of preclinical toxicology species and develop the toxicokinetic plan to support IND filing. Support human dose projections based on preclinical data to guide candidate selection. Author DMPK and BA sections of regulatory submissions (e.g., INDs, Investigator’s Brochures), and respond to regulatory queries. Contribute to the development of DMPK/BA functional processes and procedures focused on CRO interactions and organizational efficiency. Provide operational oversight for quality and performance of DMPK activities, including interactions with CROs and external project support. Contribute to the selection and qualification of CROs and external vendors. Engage closely with internal stakeholders and companies within the Flagship ecosystem. Qualifications: PhD. in pharmaceutical sciences, biochemistry, or related field with 8+ years of relevant industry experience; or M.S. with 12+ years; or B.S. with 14+ years. Proven track record representing DMPK in biologics discovery and/or development programs. Extensive hands-on experience with PK, BA, and immunogenicity assessment of biologics. Deep understanding of biologics development workflows; familiarity with small molecules or novel modalities is a plus. Working knowledge of regulatory expectations and experience contributing to…
