About The Position

We are seeking a motivated Senior Scientist to join our BioAnalytics Characterization group in the Genomic Medicine Unit within Sanofi. Candidates with no previous experience in the field of genomic medicine are still encouraged to apply – we are looking primarily for someone with strong mass spectrometry characterization experience and are committed to bridging any knowledge gaps through dedicated onboarding and training. This role offers a unique opportunity to build expertise in the rapidly growing field of genomic medicine, including viral gene therapies and lipid nanoparticles. The future of medicine is being shaped today at Sanofi — apply now and position yourself at the forefront of the next generation of transformative therapeutics. The Genomic Medicine Unit at Sanofi is dedicated to the establishment of best-in-class platforms to support development of life-changing advanced gene therapy products. The BioAnalytics Characterization group uses advanced analytical techniques for in-depth structural and functional characterization of gene therapy products in support of drug development, from pre-candidate selection through commercialization. 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
