Job title: Scientist, Rare Metabolic and Neurological Diseases

• Location: Cambridge, MA

About the Job

We are seeking a highly motivated and skilled Scientist with deep expertise in rare metabolic, and neurological diseases. The ideal candidate will have a deep expertise in part of our target disease areas, including neurodevelopmental diseases (Fragile X, Dravet, Angelman, SYNGAP1, Rett, among others), primary mitochondrial diseases, and leukodystrophies. They will bring robust hands-on experience in in vivo and in vitro target identification and validation strategies, disease modeling, combined with a strong foundation in disease biology and pathophysiology. This role will spearhead efforts to discover and validate novel therapeutic targets and strategies, leveraging both experimental and analytical approaches. They will collaborate closely with cross-functional teams to translate biological insights into therapeutic programs, contributing to the strategic expansion of our portfolio.

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.
