Sr. Process Development Associate/Process Engineer

Nkarta is a clinical-stage biotechnology company advancing the development of allogeneic, off the shelf natural killer (NK) cell therapies for cancer. By combining its cell expansion and cryopreservation platform with proprietary cell engineering technologies, Nkarta is building a pipeline of cell therapy candidates generated by efficient manufacturing processes, which are engineered to enhance tumor targeting and improve persistence for sustained activity in the body.

Founded in 2015 at the birthplace of biotechnology in South San Francisco, CA, Nkarta became a public company (Nasdaq symbol NKTX) in 2020. Our development pipeline of engineered NK cell therapy candidates consists of 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. Patient dosing began in Q4 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.
