Job title: Computational Scientist - Bioinformatician

About the job

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.

As Principal Scientist within our Computational Biologics team, you’ll work as a Computational Scientist with deep expertise in bioinformatics and protein engineering to strengthen our capabilities in computational antibody and NANOBODY® drug discovery and development. As a Computational Scientist based in Cambridge MA, you will play a pivotal role in advancing therapeutic biologics to conquer complex diseases via NGS data analysis, hit selection algorithms, pipeline development, protein structure analysis and engineering. This role encompasses both wet lab understanding and computational expertise. You will work collaboratively within our international team, while driving projects in an independent manner.

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:

To turn cutting-edge science into novel biologic candidates transforming patients’ lives, Sanofi’s Large Molecule Research (LMR) department developed a robust engine to discover and deliver innovative biologics. With digital technologies changing the practice of drug discovery and development, digital transformation is a common goal shared by all Sanofi employees. Our Digital Biologics platform is driving this transformation in computational biologics drug discovery and development.

• Biologics hit selection: Develop tools to process, analyse and interpret next generation sequencing (NGS) data, develop multi-objective hit selection approaches incorporating predictive AI/ML models to identify promising therapeutic candidates

• Biologics property optimization: Develop computational approaches to evaluate and engineer functionality and developability of biologics to ensure efficacy, safety and manufacturability

• Structural bioinformatics: Conduct structure-based analyses including structural modelling, structure-based stability assessment, protein structure-function relationship studies and structure-based protein engineering

• Pipeline development: Design and implement bioinformatics pipelines to drive antibody and NANOBODY® computational discovery workflows, adapting to evolving selection strategies

• Manage and drive projects: Independently lead and/or support computational biologics projects, identify opportunities for process improvements and technological innovations, and translate complex biological questions into actionable computational strategies

• Cross-functional collaboration: Work closely with experimental teams across research and development to validate hypotheses and discuss alternative approaches

• Scientific contribution: Maintain an active publication record and participate in the broader scientific community through conferences and collaborations
