BMS at Kendall Square is seeking a highly skilled and motivated Senior Associate Scientist with strong expertise in analytical method development to support the advancement of novel RNA therapeutics. The successful candidate will leverage biophysical and separation techniques to design, develop, and execute analytical methods that enable comprehensive characterization of lipids, antibodies, and RNA-based modalities across discovery and development stages. This role will play a critical part in generating high-quality analytical data to support product understanding, process development, and CMC strategies.

Responsibilities:

Independently design, develop, and optimize analytical methods to characterize RNA-based therapeutics, lipid nanoparticles, and related components.

Support routine and platform analytical testing across safety, identity, content, purity/impurity, potency, and general quality attributes for LNP-encapsulated RNA.

Lead phase-appropriate method lifecycle activities, including method development, qualification, validation, and transfer to internal and external laboratories (e.g., CROs/CDMOs), with authorship of SOPs, protocols, and technical reports.

Collaborate cross-functionally with process development, formulation, research, and manufacturing teams to support analytical development, troubleshoot issues, and enable program milestones and timelines.

Troubleshoot complex analytical challenges, interpret data, and provide scientifically sound recommendations to resolve issues and improve assay performance and robustness.

Perform and oversee routine and non-routine analytical testing, including data review, verification, and interpretation to ensure data quality, integrity, and compliance with internal standards.

Operate, maintain, and troubleshoot analytical instrumentation.

Analyze and communicate complex analytical data, generating clear, concise reports and presentations to inform technical teams and leadership decisions undefined

Qualifications:

B.S./M.S. in Analytical Chemistry, Biochemistry, or a related discipline with 2+ years of relevant CMC-related experience. PhD. candidates with appropriate experience will be considered for this position.

Hands-on experience with HPLC/UHPLC (IP-RP, RP, CAD detection) for RNA, lipid, and impurity quantitation.

Hands-on experience with biophysical/biochemical characterization techniques: DLS, RiboGreen, ELISA, Raman spectroscopy, light/confocal microscopy, UV-Vis spectrophotometry

Ability to manage multiple projects and priorities in a fast-paced environment

Strong technical writing skills for reports, protocols, and regulatory documentation

Familiarity with regulatory expectations (e.g., ICH, FDA) for analytical data and submissions

How we calculate "similar"

No black box, no LLM guesswork: a deterministic score built from four normalized attributes. Here's this role's own peer group at different match levels, so you can see the mechanism, not just the result.

Every comparison starts from the same 100-point budget: 25 for working in the same function, 40 for the same therapeutic area, 20 for the same or adjacent seniority, 15 for the same country. A dimension we can't confirm on both sides contributes nothing, never a guess, never a free pass.

Unmatched or unknown dimensions score exactly the same: 0 points, never a partial guess. A role we know almost nothing about beyond its function bottoms out at 25%; it never inflates to 100% just because there's little to compare against. Seniority uses a defined ladder (Associate → Manager → Associate Director → Senior → Principal → Director → Senior Director → Executive/VP) so "Director" and "Senior Director" count as adjacent, but "Director" and "Executive/VP" do not.
