Job title:  Senior Principal Scientist/Principal Scientist, Real-World Evidence & Disease Genomics

• Location: Cambridge, MA

About the Job

Join Sanofi's Target, Disease and Systems Biology (TDSB) team and become a key contributor to our Disease Genetics and Genomics cluster. In this role, you will sit at the intersection of real-world evidence generation and disease genomics, leveraging large-scale electronic health records (EHRs) and population biobanks to transform how we understand disease trajectories and evaluate indication expansion opportunities. Working alongside world-class computational and experimental scientists, you will help shape the future of drug discovery and development across Sanofi's therapeutic areas — from early indication prioritization to business development evaluation of external assets. 

Within our Disease Genetics and Genomics cluster, you'll play a pivotal role in: 

• Developing and applying cutting-edge EHR-based methods, including foundation models and classical statistical approaches, to generate real-world evidence at scale to understand disease trajectories. 

• Defining rigorously curated disease cohorts and Progression endpoints to support target trial emulation and genomic analyses 

• Driving Sanofi's engagement with leading population biobanks, including FinnGen and All of Us, to generate insights with direct impact on R&D strategy 

You will operate in an agile, fast-paced environment with access to industry-leading data infrastructure, working in close collaboration with disease area experts, medical teams, and therapeutic program leads to ensure your work translates into tangible impact on patients' lives. 

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
