Sr. Process Development Associate/Process Engineer

Founded at the birthplace of biotechnology, Nkarta's mission is to discover, develop and deliver novel off-the-shelf (e.g. allogeneic) natural killer (NK) cell therapies that profoundly impact patients' outcomes and survival . The company is based on the proprietary, robust and well-characterized NK cell expansion technology pioneered by Dr. Dario Campana. Nkarta is focused on leveraging the inherent power of NK cells to identify and kill abnormal cells and recruit adaptive immune effectors to generate responses that are deep and durable.

Nkarta combines its NK cell expansion and cryopreservation platform with proprietary cell engineering technologies to generate an abundant supply of NK cells, engineer enhanced NK cell recognition of tumor targets, and improve persistence for sustained activity in the body for the treatment of cancer.

Founded in 2015, Nkarta became a public company (Nasdaq symbol NKTX) in 2020. Our development pipeline of engineered NK cell therapy candidates consists of two co-lead programs, NKX101 and NKX019. The IND for NKX101 for the treatment of relapsed or refractory AML and higher-risk MDS was accepted by the FDA in July 2020. We expect to begin dosing patients in this study by the end of 2020. As we broaden the development of NKX101, we also plan to initiate studies in solid tumors. Our second co-lead program, NKX019, is designed to target B cell lymphomas. We plan to file our IND for NKX019 with the FDA in early 2021. In addition, we recently completed the construction of a GMP compliant clinical manufacturing facility in our South San Francisco location designed to produce viral vector and supply our initial clinical trials.
