Associate Principal Scientist, Upstream Development

Merck Merck · Pharma · NJ

Merck is seeking an Associate Principal Scientist for their Biologics Process Research & Development organization. The role focuses on developing drug substance manufacturing processes for biologics, including cell culture processes, process characterization, and regulatory filing activities. The candidate will collaborate with cross-functional teams, advance upstream platform processes, and engage with external partners. Requires a Ph.D. or Master's/Bachelor's with significant experience in chemical engineering, Bioengineering, or a related field, with hands-on experience in mammalian cell culture and fed-batch processes.

What you'd actually do

  1. Participates in and/or leads upstream process development of first-in-human and commercial processes by efficiently developing high yield, robust, and scalable cell culture processes.
  2. Responsible for process development, process characterization, and regulatory filing activities to ensure a smooth and clear path to successful PPQs and BLAs for the company's pipeline.
  3. Partner with colleagues in Discovery, Cell Line, Downstream Process Development, Analytical Sciences, and Manufacturing to develop integrated clinical and commercial process and manufacturing solutions that achieve quality by design targets with robust control strategies.
  4. Advancing the upstream platform processes through creative process improvement initiatives to increase operational efficiency and reduce costs.
  5. Collaborate with academia, industry partners, and vendors to drive development, innovation, and adoption of new process technologies.
