About The Position

Regeneron Pharmaceutical's Analytical and Biological Mass Spectrometry Group (ABMS), located in Tarrytown, NY, is seeking a highly motivated Sr. Scientist. In this role, you will work in an innovative mass spectrometry (MS) lab and develop LC-MS methods for characterizing biotherapeutic products to support all stages of drug development, from early-stage candidate selections to late-stage regulatory submissions. You will conduct and develop innovative technologies to support a diverse Regeneron's R&D pipeline.

Requirements

• BS (10+ years), MS (7+ years) or PhD degree (0-3+ years) in Analytical Chemistry, Biochemistry, Pharmaceutical Sciences, or a closely related field.
• Experience with charge detection mass spectrometry (CDMS) is strongly preferred.
• Experience applying LC-MS to extended characterization of AAV and monoclonal antibodies to support product and process development is a plus.
• Extensive experience with advanced mass spectrometers (Q Exactive Plus, Q Exactive UHMR, Q-TOF, etc.), liquid chromatography, and data processing software (Protein Metrics, Skyline, UniDec etc.) is desired.
• Experience with experimental design and data analysis (e.g., molecular modeling, graphing, and statistical analysis) is a plus.

Responsibilities

• Design, execute, and clearly communicate analytical characterization for biotherapeutics, including adeno-associated virus (AAV), monoclonal and bispecific antibodies, Fc-fusion proteins, and other modalities, to support drug development.
