Job Description

The Large Molecule Research organization at Sanofi (Cambridge, USA) is seeking a Senior Principal Scientist, Lab Head to lead a research group composed of PhD and non-PhD scientists focused on two key activities: (1) generation of novel antibody drugs using in vitro antibody discovery platforms delivering into and enriching a competitive pipeline in Oncology, Immunology & Inflammation, and Rare & Neuroscience; and (2) developing new technologies to advance the discovery and lead optimization of antibodies contributing to our First-in-Class, Best-in-Class portfolio. The successful candidate will be seen as a highly experienced scientific leader with deep expertise in discovering antibodies involving phage-to-yeast libraries coupled with machine learning and other in silico tools. The candidate will lead his/her research teams and collaborate across all therapeutic areas at Sanofi, as well as other Research Platforms (e.g., Nanobody, Translational Sciences, etc.).


  • Lead a team of PhD and non-PhD scientists directly as well as via matrix management to execute on discovering antibodies and or other biologic building blocks to support Sanofi’s pipeline of biologic drugs.

  • Provide scientific leadership and technical guidance to build a robust biotherapeutics portfolio, including guidance on discovery campaign screening strategies, triaging across discovery platforms, setting criteria for molecule progression, and management of external/internal partners.

  • Continuously look at opportunities to improve the efficiency and success of antibody discovery workflows.

  • Develop new technologies and platforms to stay at the cutting edge, incorporate new technologies. and support integration of new technical innovations across the global antibody discovery teams.

  • Oversee continuous modernization of lab infrastructure, including establishment of streamlined lab and data workflows, and supporting data management objectives.

  • Support the further development of computational expertise within the team and workflows.

  • Offer scientific leadership and guidance cross-functionally, especially with the Therapeutic Areas, the interplay between understanding the biology of the disease and the molecule platforms.

  • Assist business development in assessing in and out-licensing opportunities.

  • Contribute to patent filings and publications and present research finding to various audiences.

  • Identify opportunities for growth of the group and department into new areas to foster efficiency.

  • Present findings in different forums with clarity and line of sight

Must have qualifications

  • Ph.D. and postdoctoral work in Biochemistry, Immunology , Molecular & Cell Biology or similar fields with 8+ years of experience leading a high performing multidisciplinary antibody drug discovery team.

  • Extensive experience working with all major in vitro antibody discovery and optimization platforms.

  • Recognized scientific leader in the field of antibody discovery with consistent publications in top-tier journals, presentations at key scientific conferences.

  • Exceptional communication skills, innovative mindset and ready to step out of the box for creating and exploring new ideas, engaged and passionate about antibody drug discovery with a zeal to take ownership and accountability.

  • Knowledgeable in computational methods employed during antibody discovery and engineering (e.g., NGS sequence and analysis, computational library design, use of in silico developability prediction methods, etc.).

  • Strong publication history and active networking within the antibody discovery and engineering community.

  • Hands-on experience with high throughput methods employed end-to-end to discover and characterize antibodies.

Additional qualifications

  • Experience with and/or interest for artificial intelligence-based discovery of antibodies.

  • Experience in alternative to antibody scaffolds as biologic drugs or as building blocks for multi-specific antibody generation.
