Job Opening: Research Scientist, CAR-NK Cells

//Job Opening: Research Scientist, CAR-NK Cells


Poseida Therapeutics, Inc. is seeking an outstanding candidate to join our immuno-oncology team at San Diego, CA. The Scientist will have a detailed knowledge of Natural Killer (NK) cell signaling, NK cell therapies, and tumor immunology.  Expertise in the culture, manipulation, and characterization of NK cells expressing anti-tumor effects is critical. The successful candidate will primarily perform experiments for the development of cellular therapies against cancer using NK, among others. Additionally, experience with chimeric antigen receptors (CARs) and/or NK cell allotransplant is a plus. The role includes developing and optimizing methodologies and assays as well as planning, executing, interpreting, and troubleshooting experiments using good scientific judgment. The scientist will demonstrate excellent oral and written communication skills, work well independently and as part of a team, and be able to work on multiple projects simultaneously. The position is a hands-on, laboratory-based role with the possibility of direct reports.

Poseida is currently developing CAR-T and gene therapy products for cancer and orphan diseases. Poseida is a pre-IPO company with $30M in Series A financing and is currently partnered with J&J’s Janssen to develop allogeneic CAR-T therapies against cancer. Poseida has entered into a worldwide License Agreement with Janssen to research, develop, manufacture and commercialize licensed products using Janssen Centyrin technology. Centyrins are non-scFv, alternative binders that are fully human and one fifth the size of a traditional scFv. In addition, Poseida boasts best-in-class genome engineering capabilities for stable transgene integration or targeted gene disruption. Proprietary tools include piggyBac™ DNA Modification System (capable of delivering 300kb+ of cargo for stable integration and long-term expression), Footprint-Free™ Gene Editing System, NextGEN™ CRISPR, and XTN™ TALEN, which are synthetic, non-viral, and can be surgically precise. Poseida aims to advance the first CAR-T product against multiple myeloma and gene therapy product against Progressive Familial Intraheptic Cholestasis 3. Please visit for more information.
