About the Job

Looking to launch your career at the cutting edge of healthcare? Sanofi offers mentoring and guidance from inspiring leaders, with a chance to make an impact on the lives of people worldwide. We are looking for a highly motivated Spring Co-op to join the Process and CMC Data Science team.

Sanofi is a global healthcare company that helps the world stay ahead of infectious diseases, delivering more than 500 million vaccine doses a year. Our teams explore new technologies to protect people and promote healthy communities.

This Co-op is based in the Data and Computational Science (DCS) department within Sanofi's mRNA Center of Excellence (mRNA CoE). You will develop first-principle, machine-learning (ML), and hybrid models for critical drug-substance unit operations, including In-Vitro Transcription (IVT), Tangential Flow Filtration (TFF), and Chromatography, to speed up mRNA-based process development.

You will gain hands-on experience with mRNA technology and drug-substance manufacturing while applying advanced modeling techniques. The role sits at the intersection of data science and process engineering.

Main Responsibilities

• Develop and validate first-principle, ML, and hybrid models for drug-substance unit operations such as IVT, TFF, and Chromatography, working with your supervisor and cross-functional team members.
• Investigate how process parameters affect critical quality attributes (CQAs) and quantify the related uncertainties using statistical and computational methods.
• Design and run Design of Experiments (DoE) for model structure selection, parameter estimation, and process optimization.
• Analyze experimental and simulation data to produce actionable insights for process development decisions.
• Document modeling workflows, results, and recommendations in clear technical reports and presentations.
