Research Scientist T Cell Metabolism

Poseida Therapeutics, Inc. is seeking an outstanding candidate to join our immuno-oncology team at La Jolla, San Diego, CA. The T Cell Metabolism Scientist will design and perform experiments optimizing the manufacture of chimeric antigen receptor (CAR)-T cell therapies of the T stem cell memory subset (TSCM), which are an ideal cell population for adoptive immunotherapy since they are long-lived, self-renewing and multi-potent. The hypothetical attributes of a CAR-T product with a high percentage of TSCM include enhanced durability, as well as potency against solid tumors. Investigation will focus on immunometabolism for understanding and optimizing the non-viral piggyBac™ CAR-Tscm manufacturing process via the use of in vitro human cell-based assays assessing T cell proliferation, phenotype and function. The position will play a critical role in the evaluation and identification of manufacturing strategies for enhancing metabolic fitness and bioenergetic profile of CAR-T products.  The successful candidate will demonstrate excellent oral and written communication skills, work well both independently and as part of a team, and be able to work on multiple projects/product candidates simultaneously.  Broad expertise in cellular metabolism, key regulatory pathways, T cell culture, and flow cytometry is required for this role.  The position is a hands-on, laboratory-based role with the possibility of direct reports.

Poseida Therapeutics is translating best-in-class gene engineering technologies into lifesaving cell therapies. The company is developing CAR T-cell immunotherapies for multiple myeloma, prostate and other cancer types, as well as gene therapies for orphan diseases. P-BCMA-101 is Poseida’s lead CAR-T therapy currently in Phase 1 clinical development for the treatment of multiple myeloma. Poseida has assembled a suite of industry-leading gene engineering technologies, including the piggyBac™ DNA Modification System, TAL-CLOVER™ and Cas-CLOVER™ site-specific nucleases, and Footprint-Free™ Gene Editing (FFGE).
