About the Job

At Sanofi we are committed in our quest to be a world-class biologics research organization and are steadfast in our goal to bring next generation, transformative therapies to patients. Our global Large Molecule Research (LMR) organization is focused on antibodies and NANOBODY® molecules as therapeutic modalities. Our platform enables and partners closely with other research platforms and Sanofi’s therapeutic areas (Immunology & Inflammation, Immuno-Oncology, Rare & Neurologic Diseases) in the discovery and ultimate delivery of new candidate molecules.

We are seeking a talented and highly motivated Senior Associate Scientist to join our dynamic team in the Molecular, Expression and Screening Technologies (MEST) Group within Sanofi’s North America R&D LMR organization.
