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.
Sanofi is seeking a highly motivated scientist to conduct preclinical drug discovery research for retinal diseases, including age-related macular degeneration and glaucoma. As a Scientist in the Retinal Degeneration group within Ophthalmology Research, you will design and execute studies to validate therapeutic strategies and discover promising drug candidates. The successful candidate will work collaboratively in matrixed, cross-functional teams to generate high-quality and comprehensive data packages to nominate and advance therapeutic candidates toward clinical development. This position offers the exciting opportunity to make significant contributions to the future of ophthalmology therapeutics and bring transformative vision-preserving treatments to patients around the world.
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?
Main Responsibilities:
Design, execute, and document translational research studies to validate therapeutic targets and discover preclinical drug candidates
Develop and optimize molecular, biochemical, and cellular assays to assess disease processes, target activity, and biomarkers in models of retinal disease and degeneration
Perform experiments using genetic, biologic, and small molecule perturbations to validate targets, evaluate therapeutic strategies, and assess the pharmacology and efficacy preclinical candidates
Analyze and interpret experimental data to support target prioritization, preclinical candidate selection, and go/no-go decisions
Actively contribute to interdisciplinary research projects in a highly collaborative and matrixed manner
Prepare high-quality presentations and documentation to support project deliverables, publications, patent filings, and regulatory filings
Effectively communicate findings internally and externally through presentation and publication
