We are seeking a highly motivated bioanalytical scientist who can contribute to the development and implementation of state-of-the-art quantitative and qualitative analytical and bioanalytical methods to support biopharmaceuticals in discovery and preclinical development pipeline at Regeneron. The successful candidate need function well in a collaborative, fast-paced, multidisciplinary team environment.

**A Typical day in this role looks like:**

+ Primarily responsible for developing LC‑MS–based bioanalytical methods in various biological matrices.
+ Apply these methods to quantify biotherapeutic levels, assess in vitro stability, evaluate in vivo biotransformation, and measure biomarkers (small molecules, peptides, and proteins).
+ Support characterization of drug candidates and critical reagents within the discovery pipeline.
+ Collaborate closely with chemistry, conjugation, biology, PK, and TK teams to ensure strong experimental design, accurate data inte...
