Senior Scientist – Vaccines Full-time NEW

Senior Scientist – Vaccines

Join the team protecting half a billion lives every year with next-gen science, mRNA innovation, and AI-driven breakthroughs. In Vaccines, you'll help advance prevention on a global scale – and shape the future of immunization.

The Global Clinical Immunology (GCI) organization, part of Late Stage Global Immunology within Vaccines R&D, specializes in developing, validating, and deploying regulated bioanalytical assays to assess immune responses to vaccines throughout their lifecycle. Our mission is to provide specialized immunology expertise and generate robust clinical datasets that inform decision-making for both clinical development and post-licensure activities. Our GCLP-compliant bioanalytical laboratories are based in Swiftwater, PA. The Senior Scientist for the Logistics and LCM Platform will design, develop, qualify, validate, and implement ligand-binding and functional immunoassays that support clinical endpoints across the Sanofi viral and bactericidal vaccine portfolio. The role demands expertise in methods and technologies that include ELISA, SBA, ECL, neutralization assays, and automated platforms.

The candidate will also be expected to provide mentorship and effectively supervise and train lab personnel to perform assigned tasks while ensuring applicable compliance and regulatory agency standards are met. The candidate will serve as key resource as expert technical representation within the organization and on multidisciplinary teams. This is a laboratory-based role requiring at least 60% of time conducting hands-on experimental work while driving innovation in assay development.
