About the Job

Are you ready to shape the future of medicine? The race is on to speed up drug discovery and development to find answers for patients and their families. Your skills could be critical in helping our teams accelerate progress. 

We seek a highly motivated candidate to join Cell Line Development (CLD), responsible for generating mammalian cell lines for Sanofi’s R&D Biologics pipeline and implementing new technologies and processes for continuous platform improvement.  CLD, located in Framingham MA, is a global function, supporting research and early development projects at three Sanofi R&D Hubs (North America, France, Germany), and team members routinely work with colleagues at different sites. 

The person in this role will work in a high-performing, fast-paced collaborative environment, ensure project goals and timelines are met, and help drive optimization for cell line production of biologics including antibodies and diverse, novel formats.  Work will directly support development projects within Sanofi’s pipeline. The position also provides the opportunity to work on global teams, contribute to operational excellence and other transversal initiatives, and have a direct impact on shaping our future cell line expression platforms.

We are an innovative global healthcare company with one purpose: to chase the miracles of science to improve people’s lives. We’re also a company where you can flourish and grow your career, with countless opportunities to explore, make connections with people, and stretch the limits of what you thought was possible.
