** About the job:
** The Scientist for the Bacteriology team will design, develop, qualify, validate, and interpret functional serological assays, including serum bactericidal assays (SBA), to characterize immune responses for clinical studies across Sanofi's vaccine portfolio. In addition to deep immunoassay expertise, the candidate will provide mentorship and effectively collaborate with Bacteriology lab personnel to perform assigned tasks while ensuring compliance with regulatory agency standards.

The candidate will serve as a key technical resource, providing expert representation within the Bacteriology group and on multidisciplinary teams. The ideal candidate will remain current on functional immunological assays specific to bacterial pathogens and embrace the evaluation of new technologies and automation to advance our testing capabilities. This is a laboratory-based role requiring a high percentage of time conducting hands-on experimental work while driving innovation in assay development.
To establish and implement complex functional immunoassays for bacterial pathogens to use as clinical endpoint testing, as well as integration of automation technologies to increase assay throughput and reproducibility. This role operates within a regulated laboratory environment where data quality and timeline adherence are critical for vaccine development decisions. Key challenges include maintaining assay consistency while implementing automation, managing multiple concurrent projects, and adapting established protocols to different bacterial pathogens.  

Join the engine of Sanofi’s mission — where deep immunoscience meets bold, AI-powered research. In R&D, you’ll drive breakthroughs that could turn the impossible into possible for millions.  
** About Sanofi:
** We’re an R&D-driven, AI-powered biopharma company committed to improving people’s lives and delivering compelling growth.
