Job Title:  IDD IVB Cell Biology Summer-Fall 2026 Co-op

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. 

Join Sanofi’s innovative team and contribute to cutting-edge drug discovery research. We are looking for a motivated student to join our Biochemistry team and utilize numerous assays to investigate small molecule modulation of target protein activity.  Overall, the student will master assay development and small molecule screening processes, such as assay optimization, protein quantification, automation and statistical data handling methods.  

This position will focus on setting-up and learning cell-based techniques aimed at understanding the modulation of various targets within the immunological pathways.   In this position, the scientist will be responsible for characterizing several cell types using a matrix of immunology triggers to stimulate the downstream processes.  The kinetics of the pathway stimulation as well as the sensitivity of the different processes to inhibition will be characterized. Overall, the student will learn sterile cell culture techniques, assay development and optimization processes, live-cell imaging skills, statistical data handling as well as gain a broad understanding of drug development.

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

• Variety of cell -based assays that monitor cellular functions. 

• Learn culturing techniques for several different mammalian cell lines and primary cells (PBMC, iPSC)  

• Get exposure to multiple cellular readouts including Reporter gene assays, Cellular imaging techniques and Biomarker detection via AlphaLISA and HTRF techniques.

• Learn procedures for High Throughput Assay Validation

• Analyze and interpret data to support the development of novel drug candidates.

• Document experimental results and present findings to the team.

• Participate in lab meetings and contribute to the advancement of ongoing research projects.
