Senior Scientist

Job title: Senior Scientist

Location: Framingham, MA

About the Job

We seek a highly motivated candidate to join Cell Line Development (CLD), responsible for generating mammalian cell lines for Sanofi's R&D biologics pipeline and implementing new technologies and processes for continuous platform improvement. CLD, located in Framingham MA, is a global function, supporting research and early development projects at three Sanofi R&D Hubs (North America, France, Germany), and team members routinely work with colleagues at different sites.

The person in this role will work in a high-performing, fast-paced collaborative environment, ensure project goals and timelines are met, and help drive optimization for cell line production of biologics including antibodies and diverse, novel formats. Work will directly support development projects within Sanofi's pipeline. The position also provides the opportunity to work on global teams, contribute to operational excellence and other transversal initiatives, and have a direct impact on shaping our future cell line expression platforms.

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.

About Sanofi

We're an R&D-driven, AI-powered biopharma company committed to improving people's lives and delivering compelling growth. Our deep understanding of the immune system – and innovative pipeline – enables us to invent medicines and vaccines that treat and protect millions of people around the world. Together, we chase the miracles of science to improve people's lives.

Main Responsibilities

• Technical oversight and delivery of end-to-end cell line development work packages (as CLD Lead & Operator) to meet deliverables for preclinical and clinical development projects, including reports and presentations to stakeholders.

• Perform cell culture techniques for both pool and clone generation of expressive populations.

• Actively engage and contribute to optimize cell line generation process towards using an automation-enabled high-throughput cell line platform.

• Represent the CLD function on project teams and within Global CMC, making decisions for cell line activities and effectively communicating results, progress and plans. Active engagement and collaboration with global DS teams as the CLD representative.

• Drive innovation strategies for generating cell lines, to ensure "right first time" delivery of commercial-ready cell lines.

• Active engagement with Research functions ensuring smooth transition of projects and data.

• Compliance with all applicable regulations, ensure that work performed is conducted in a safe and compliant manner, ensure maintenance of proper records in accordance with SOPs and policies.

• Prepare and review documentation for regulatory submissions.
