About The Position

Sanofi is seeking a highly motivated Spring Co-op to join its RNA Production team. The co-op will support mRNA production for drug targets, including batch production, characterization, and process optimization. The position focuses on synthesizing and purifying a wide range of mRNA constructs in parallel, performing analytical characterization for the mRNA drug-substance release panel, and contributing to improvements in mRNA sequence design, production, and purification. The co-op will also help evaluate and implement new technologies, optimize existing workflows, and prepare technical reports, presentations, and recommendations for management and other stakeholders. This is primarily a lab-based position in Waltham, Massachusetts, for six months.
