Principal Investigator – Downstream Processing | Thermo Fisher Scientific | San Diego

How will you make an impact?

The Science & Technology Team (STT) is passionate about developing end-to-end, standardized workflows and assays to support nucleic acid, viral vector, and cell therapy cGMP manufacturing. The Manager will build and lead a robust technical team proficient in downstream processes using robust platforms that ease the path towards GMP manufacturing. The motivated individual will lead viral vector downstream processing, scale-up, and continuous process improvements.

What will you do?

  • Utilize skills to implement end-to-end, robust downstream processing for Lab/pilot-scale and high-through-put viral vector preps
  • Lead planning, scheduling, and execution of experiments. Developing and executing filtration and chromatography separation methods for viral vector purification.
  • Direct and coordinate review of experiments, execution, data, and reporting of work completed; generate protocols and methods; address and resolve technical issues
  • Lead downstream process lab, delegate, and share lab management duties. Coordinate with technical operations and R&D to deliver project timelines. Evaluate and implement new methods, processes, techniques, and technology platforms
  • Hire, train, mentor and lead scientists and technicians involved in downstream viral processing. You will provide strong leadership, mentorship, and scientific oversight to internal team members.
  • Work in a matrix environment, interact externally and internally across technical teams, divisions, and functions; collaborate with clients, and support translational services
