The Biotherapeutics Development-Analytical Development (BioTD-AD) group is seeking an upbeat, highly motivated leader to characterize next-generation, iPSC-based CAR-T cell platforms for allogeneic cell therapies. The Principal Scientist will establish the technical strategies for generating engineered iPSC-derived g/d T-cell therapies for oncology and other indications.

The Principal Scientist will shape the strategies required for in depth process and product understanding and provide technical and strategic leadership to the function and to the Chemistry Manufacturing Control (CMC) teams. The individual will have a strong foundation in human T cell and stem cell biology. Experience with the design, execution and optimization of a broad range of in vitro cell based characterization assays, and will have the opportunity to engage in multi-functional teams. They will learn from and contribute to industry-leading drug discovery/development programs that has brought numerous quality therapeutics to patients and has made significant contributions to human health.


Key Responsibilities:

  • Develop characterization strategies and implements plans to characterize iPSCs, cell and gene engineering, and cell differentiation, in particular gamma/delta T cells, NK cells or related cell types.
  • Lead a team of scientists developing and optimizing analysis methods that fully characterize human iPSCs and iPSC-derived cells using multi-parameter flow cytometry and in vitro assays for cell proliferation, cytokine secretion, polyfunctionality, and target cell killing.
  • Manage characterization plans for assessing on-target and off-target editing activity by ICE, flow cytometry, ELISA, qPCR, western blot, and others.
  • Direct technical forums both internal and external to the company to share knowledge and approaches related to cellular characterization strategies as they relate to cell-based therapies (CAR-T, CAR-NK, etc.).
  • Engage and/or lead technical investigation strategies in support of product investigations with respect to clinical outcomes or adverse events driving to root cause.
