About The Job

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. Ready to get started?

The Commercial Process Development team, part of the CMC Synthetics Platform within the Sanofi R&D organization, is responsible for mid-to-late-stage process development for drug substances undergoing clinical development and for the chemical process to deliver the drug substance quality target profile. The Chemical Process Development team owns the eco-design strategy for the drug substance and, in collaboration with Analytical Sciences, Process Engineering and Clinical Manufacturing/External Technologies, defines the control strategy for the DS synthetic process. We strongly believe that innovation in synthetic concepts and technologies, leveraging modeling, AI/ML and integration of biocatalysis are key drivers to transform drug substance process development to deliver drug substances in the most efficient, robust, economical, environmentally benign, and intrinsically safe way.

We are looking for a highly motivated and collaborative individual with expertise in synthetic organic chemistry, late-stage clinical development experience to join our Process Chemistry team at the Principal Scientist level. Under the direction of Process Chemistry R&D leadership, the primary responsibility of this role is to perform and oversee multi-step route evaluation and route development activities, with the aim of establishing commercial drug substance manufacturing processes through management and execution of internal and outsourced laboratory activities. This role may oversee the activities of one or more collaborators and be responsible for their professional development.
