The ideal candidate will play a pivotal role in advancing analytical methods to support the development and manufacturing of innovative RNA therapeutics. Key responsibilities will center on the utilization of chromatography and mass spectrometry for method development, with a focus on creating and implementing assays to characterize both RNA drug substance and lipid nanoparticle (LNP) drug products. Responsibilities: Serve as a subject matter expert in separation science, developing novel analytical methods to characterize RNA-based products and their delivery systems. Investigate new techniques and technologies to provide analytical support for research and development activities across different stages of product development. Establish methods to identify and characterize impurities related to LNP drug products and assess critical quality attributes of protein-conjugated LNPs. Participate in the transfer of methods to internal and external testing laboratories as necessary, providing expertise and documentation—including standard operating procedures (SOPs), technical reports, and method qualification plans—to facilitate method verification, qualification, and validation. Collaborate with internal teams, including RNA Process Development (PD), LNP PD, research, and preclinical manufacturing, as well as broader BMS groups, to meet program timelines and support routine testing requirements. Lead troubleshooting efforts and provide guidance when analytical challenges arise. Supervise routine analytical testing, review data, and perform testing as needed. Operate and maintain essential instruments such as high-performance liquid chromatography (HPLC) and mass spectrometry. Document and communicate results effectively to team members and leadership. Approach analytical challenges with creativity, contributing to the development of a cutting-edge analytical platform. Qualifications: Ph.D. in Analytical Chemistry, Biochemistry, or a related discipline with at least eight years of Chemistry, Manufacturing, and Controls (CMC) experience. Candidates with a B.S. or M.S. and relevant experience will also be considered. Extensive experience analyzing various sample types using chromatography (HPLC/UPLC) across different separation modes, including reversed phase, ion exchange, size exclusion, and asymmetric flow field-flow fractionation. Proficiency in associated detection methods such as mass spectrometry (MS), multi-angle light scattering (MALS), and charged aerosol detection (CAD) is required. Hands-on expertise in method development and impurity characterization for LNP-related impurities using various detection techniques is highly desirable. Experience with RNA/oligonucleotides, lipid nanoparticles, and/or proteomics is strongly preferred. Familiarity with Good Practice (GxP) principles for development, documentation, and qualification is preferred. Experience with early-stage product development is advantageous. Demonstrated problem-solving abilities and the capacity to work both independently and collaboratively within a team. Strong attention to detail when executing assays and documenting results. If you come across a role that intrigues you but doesn’t perfectly line up with your resume, we encourage you to apply anyway. You could be one step away from work that will transform your life and career.
