About The Position

We are looking for a highly motivated and innovative scientist to join the Target, Disease & Systems Biology (TDSB) department at Sanofi as a Senior Scientist. In this role, you will collaborate across the Pre-clinical Omics research cluster to investigate disease biology, uncover novel pathways and mechanisms, and identify strategies to address unmet medical needs across a range of therapeutic areas. This position offers the opportunity to apply cutting-edge molecular biology and spatial technologies to advance our therapeutic discovery efforts. The ideal candidate will bring strong technical expertise in bulk RNA-seq, single-cell/single-nucleus RNA-seq (sc/snRNA-seq), spatial transcriptomics, and spatial proteomics to support a broad scope of research initiatives. We are seeking someone who can lead and execute scientific research, analyze and present complex data, and communicate effectively with both expert and non-expert audiences. Strong organizational skills—including meticulous record keeping, planning and scheduling, and maintaining laboratory equipment—are essential. The successful candidate will be curious, bold, and creative in exploring new scientific directions and proposing innovative experimental approaches. At Sanofi, we are an innovative global healthcare company driven by a singular purpose: to chase the miracles of science to improve people’s lives. We offer a dynamic environment where you can thrive professionally, build meaningful connections, and push the boundaries of scientific discovery. Ready to begin your journey?
