Description du poste

At Regeneron, we use science and innovation to develop life-changing medicines for people with serious diseases. We are seeking a highly motivated Sr. Associate Scientist to join the Bioconjugate Analytics (BCA) team within the Analytical and Biological Mass Spectrometry (ABMS) Group. In this role, you will develop and apply LC-MS-based analytical methods to advance Regeneron’s bioconjugate pipeline across all stages of development, including antibody-drug conjugates (ADCs), antibody-oligonucleotide conjugates (AOCs), antibody-tethered ligands (ATLs), and other emerging bioconjugate modalities. You will apply state-of-the‑art mass spectrometry and analytical technologies to characterize bioconjugates and other therapeutic protein candidates, with a focus on critical quality attributes and process development, while collaborating closely with cross‑functional teams to coordinate samples, study activities, priorities, and timelines.

This position offers the opportunity to contribute to a fast-growing, science-driven organization making a meaningful difference to patients worldwide.

When & where:

• Shift Requirements: Full-time
• Location: On-site in Tarrytown, NY

What you’ll do:

• Develop and apply LC-MS-based analytical methods to characterize bioconjugates and other therapeutic protein candidates across R&D programs
• Perform sample preparation, LC-MS experiments, and data analysis using relevant software and bioinformatics tools to characterize product quality attributes; document results in electronic laboratory notebook (ELN) entries, presentations, and reports
• Support process development, R&D activities, and regulatory submissions through analytical characterization and scientific problem‑solving
• Collaborate with cross‑functional teams to understand analytical needs, coordinate samples and study activities, and align priorities, timelines, and deliverables
• Interpret and communicate scientific results through project and group meetings, technical reports, regulatory documents, internal and external conferences, and peer‑reviewed publications

The environment and physical rhythms of this role:

• This is an innovative, fast‑paced, and collaborative R&D laboratory environment requiring results-driven, highly organized, and adaptable scientific curiosity, with the ability to learn new technologies.
