You will have the opportunity to establish manufacturing platforms and guide product development through all stages of development to ensure project advancement. This role is based in Florham Park, NJ

In this role a typical day may include:

  • Independently design studies aimed at optimizing and improving expansion and manufacturability of candidate products based on the biology and the target.
  • Design and execute experiments using approaches such as DOE or QBD, maintain detailed records of results, and present results to multi-disciplinary teams and leadership.
  • Apply DOE/DQB for process characterization, establish process parameters, and contribute to CMC sections of regulatory filings.
  • Develop cell isolation, enrichment, separation and formulation protocols and technologies/ platforms to support product development.
  • Develop processes that integrate innovative approaches to increase the functional capability and yield of gd T cells.
  • Relying on an in-depth CAR-T background, perform statistical analyses using product attribute data to assist, guide, and execute comparability studies.
