About This Role
The Biomarkers and Systems Biology group is seeking a highly motivated Senior Scientist to join a dynamic team responsible for developing and executing bioanalytical strategies across multiple therapeutic programs. This role is central to the development, optimization, and validation of bioanalytical assays supporting early and late‑stage clinical studies. The Senior Scientist will lead immunogenicity strategy, provide scientific oversight of CRO‑executed assays, and contribute to global regulatory submissions.
The ideal candidate has deep expertise in pharmacokinetic and immunogenicity bioanalysis, with additional experience in biomarker methods. Hands‑on assay development experience across multiple platforms and a strong understanding of regulatory expectations are essential. The role requires scientific rigor, sound judgment, and the ability to operate effectively in a fast‑paced biotech environment.
What You’ll Do
- Lead development, optimization, and validation of PK, biomarker, ADA, NAb, and other immunogenicity‑related assays in alignment with FDA, EMA, and ICH guidelines.
- Develop and execute immunogenicity strategy, including risk assessments aligned with modality, target biology, and clinical stage.
- Oversee outsourced biomarker, immunogenicity, and bioanalytical assays at CROs, providing scientific direction, troubleshooting, protocol guidance, and data review.
- Analyze and interpret PK, PD, safety, biomarker, and immunogenicity data in close collaboration with Clinical Development, Clinical Pharmacology, Translational Medicine, Safety, and Regulatory Affairs.
- Ensure data integrity, traceability, and scientific clarity across all bioanalytical and regulatory deliverables.
- Evaluate, implement, and provide expertise across analytical platforms (e.g., ELISA, MSD, etc.).
- Prepare regulatory responses, briefing packages, and support interactions with health authorities.
- Serve as the Bioanalytical Lead on study and program teams, defining strategy and ensuring alignment with development objectives.
- Deliver scientific presentations internally and externally and contribute to manuscripts and publications.
- Promote best practices in assay development, CRO oversight, and scientific rigor.
Who You Are
You are a scientifically rigorous bioanalytical expert who develops and oversees PK, immunogenicity, and biomarker assays that support clinical programs and regulatory objectives. You excel at driving high-quality bioanalysis, interpreting complex data, collaborating across teams and CROs, and providing sound scientific and strategic guidance in a fast-paced environment.
This position is based in Cambridge, MA and requires regular onsite presence; candidates must be within commuting distance or willing to relocate.
