Principal Scientist, Upstream Process Development

Job Overview The Biologics Process Research & Development organization within our Research & Development Division is responsible for developing drug substance manufacturing processes for our company's biologics pipeline. We rapidly develop manufacturing processes for diverse biotherapeutics and efficiently manufacture material for clinical trials. We also perform late‑stage process development and characterization to prepare for commercial manufacturing, and partner with the Manufacturing Division to commercialize and launch new products. We are seeking a highly motivated and experienced Principal Scientist to lead cross‑functional teams, develop CMC packages for pipeline assets, and collaborate with Bioprocess Development colleagues on next‑generation processing strategies for assets in early‑ and late‑stage development. Job Responsibilities Lead biologic upstream process development for first‑in‑human and commercial processes, efficiently developing high‑yield, robust, and scalable cell culture processes. Provide technical direction for process development, characterization, commercialization, and regulatory filing activities to ensure a smooth and clear path to successful PPQs and BLAs for the company pipeline. Advance upstream platform process technical strategy and champion creative process improvement initiatives. Initiate new collaborations to assess new technologies and industry strategies relevant to the company. Collaborate with academia, industry partners, and vendors to drive development, innovation, and adoption of new process technologies with broad impact to projects or platform. Stay current with the external patent and literature environment; actively present and publish externally and pursue patenting strategies. Mentor and educate junior scientists. Contribute to CMC development of the company pipeline and play an active role in the development of cell culture processes and transfer to clinical and commercial manufacturing sites.
