Job Title: Scientist, Retinal Degeneration
Location: Cambridge, MA
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 an innovative and highly motivated scientist to conduct groundbreaking research to discover and validate novel therapeutic targets and biomarkers for blinding 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 high-throughput studies to elucidate the function of candidate targets and evaluate the impact of target modulation and preclinical drug candidates, individually or in combination, on disease processes and biomarkers. The successful candidate will work collaboratively in matrixed, cross-functional teams to generate, analyze, and integrate multimodal data to nominate new approaches for therapeutic intervention and prioritize preclinical drug candidates, with a focus on neuroprotective mechanisms for retinal diseases. This position offers the exciting opportunity to make significant contributions to vision-sparing therapies while working in a dynamic environment at the intersection of discovery biology and translational research.
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 and execute research studies to discover and validate targets and biomarkers for retinal diseases
Develop molecular, biochemical, and cellular assays to assess disease processes, biomarkers, and target activity in innovative models of retinal disease and degeneration
Perform high-throughput studies of genetic, biologic, and small molecule perturbations (single, dual, and multiplex) to evaluate the function of potential therapeutic targets and efficacy of preclinical drug candidates
Analyze data to nominate drug targets and prioritize preclinical candidates
Actively contribute to interdisciplinary research projects in a highly collaborative and matrixed manner across internal groups and with external partners.
Prepare high-quality presentations and documentation to support project deliverables, publications, patent filings, and regulatory filings
Communicate findings internally and externally through presentation and publication
Basic Qualifications:
Earned Bachelor’s degree plus minimum 6 years of relevant experience in an academic or biopharmaceutical setting or Master’s Degree plus minimum 3 years relevant experience in an academic or biopharmaceutical setting or Ph.D. without Post Doc experience
Research experience in ocular cell biology (e.g., RPE, RGC), and/or retinal disease processes, such as barrier function, metabolic and oxidative stress, lipid metabolism, tissue remodeling, and inflammatory signaling
Comprehensive experience with molecular, cellular, and/or biochemical methods and assay development
Cell culture experience, including work with primary cells, iPSC-derived cells, tissue explants, and/or other in vitro models relevant to ocular disease
Experience with perturbation approaches to assess gene and protein function
Demonstrated experience analyzing data using computational approaches (e.g., R, Python)
Experience preparing high-quality documents including experimental protocols, SOPs, technical reports, and presentations
Track record of contributions to research projects and scientific publications
Preferred Qualifications:
Experience with CRISPR-based technologies
Experience in high-throughput assay development
Experience using automated high-throughput screening platforms and robotics
Experience with live-cell and high-content imaging and analyses
Experience with single-cell technologies
Experience in translational sciences and drug development
Skills and competencies:
Ability to work independently as well as part of cross-functional teams in a highly collaborative and matrixed environment
Ability to multi-task and adapt to rapidly changing priorities and deadlines
Strong critical thinking, analytical, and problem-solving skills
Strong written and oral communication skills, with the ability to communicate effectively in a multidisciplinary team
Strong interpersonal skills, with the ability to build excellent working relationships
Strong attention to detail, including the ability to keep well-documented notes
