Sanofi Group Cell Culture Process Development Scientist in Waltham, Massachusetts

Position Overview:

The Genomic Medicine Unit (GMU) CMC group at Sanofi is dedicated to the establishment of best in class manufacturing platforms to support development of life-changing advanced cell and gene therapy products, including recombinant AAV vectors, lentiviral vectors and cell therapy products. This organization encompasses vector and cell line engineering, upstream and downstream process development, analytics, and clinical manufacturing support. 

The Genomic Medicine Cell Culture Process Development group is responsible for the development of AAV and Lentiviral vector production optimization and development of next generation production platforms to support high dose therapeutic products.The Scientist role requires leadership both inside and outside the laboratory and will rely on industry expertise and the exploration of novel technologies in order to build robust and efficient production processes consistent with patient safety standards.

We are looking for a candidate with experience in AAVand/or LVcell culture development, high throughput screening models (e.g. Ambr 250), scale-up and manufacturing, and technology transfer.

Key Responsibilities :

  • Independently develop, design and conduct viral vectorproduction experiments and evaluate new technologies to increase product yield and process understanding using design of experiment.

  • Develop, maintain and demonstrate advanced knowledge of principals and techniques in cell culture, bioreactor operation, viral vector production, process intensification and media development.

  • Maintain industry knowledge and awareness of new and relevant technologies, and be willing to publish findings as well as speak both internally and externally as industry leaders.

  • Lead development of study design, optimization of production process conditions, media screening and perform troubleshooting experiments and communicate findings with appropriate working groups.

  • Perform data analyses, write protocols, author development technical reports, contribute to regulatory findings and provide internal and external presentations.

  • Lead scale-up activities to implement a manufacturing process based on applied cell culture knowledge.

  • Communicate effectively with internal and external teams, e.g. CDMOs for tech transfer activities.

  • Contribute to manuscript and patent writing for external publications and patent applications.

  • Assist fellow lab associates in providing a functional, safe working environment while maximizing laboratory efficiency.
