Associate Scientist – Analytical and Biological Mass Spectrometry (ABMS) Full-time

Associate Scientist

Regeneron Pharmaceutical's Analytical and Biological Mass Spectrometry Group (ABMS), located in Tarrytown, NY is seeking a highly motivated Associate Scientist. In this role, you will work in an innovative mass spectrometry lab and execute 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 perform routine technical tasks to support a diverse R&D pipeline.

A Typical Day in This Role Looks Like:

• Execute established protocols and clearly communicate analytical characterization of biotherapeutics, including monoclonal and bispecific antibodies, Fc-fusion proteins, and other modalities (adeno-associated virus, siRNA, etc.) to support drug development.
• Execute characterization activities, with an emphasis on intact-mass LC-MS technique to elucidate critical quality attributes such as charge variants, size variants, and post-translational modifications.
• Provide analytical support for cross-functional teams, including formulation development, upstream/downstream process development, and manufacturing to solve drug development challenges.
• Independently conduct sample preparation and LC-MS analyses in compliance with SOPs and document experimental procedures and results in electronic laboratory notebook (ELN).
• Use strong organization and communication to plan and prioritize work, manage and visualize data, and deliver clear, timely updates.

This Role May Be for You If:

• You thrive in a fast-paced, collaborative environment and consistently deliver results with efficiency and ownership.
• You quickly learn new technologies, solve complex problems, and demonstrate strong passion for science and innovation.
• You are self-motivated and proactive, with the ability to prioritize effectively and drive work forward with minimal supervision.

To be considered for this role, you must have a bachelor's or master's degree in Analytical Chemistry, Biochemistry, Pharmaceutical Sciences, or a closely related field. Familiarity with advanced mass spectrometers (Q Exactive Plus, Q Exactive UHMR, Q-TOF, etc.), liquid chromatography, liquid-handling systems and data processing software (Skyline, Protein Metrics, etc.) is desired. Exposure to automated liquid-handling systems (e.g., Bravo, KingFisher) is a plus; willingness to learn is valued.
