Director, Clinical Trial Operations

About Us Nkarta is a publicly traded (Nasdaq symbol NKTX), clinical-stage biotechnology company headquartered in South San Francisco, focused on advancing the development of allogeneic, off-the-shelf natural killer (NK) cell therapies to treat autoimmune disease. Founded in 2015, Nkarta is on a mission to harness the body’s natural killer cells – the immune system’s first responders – to deliver a safe, accessible form of cell therapy to treat B cell-mediated autoimmune diseases. Our vision is to make cell therapy more broadly available to patients by pioneering allogeneic NK cells that can be dosed in outpatient, community health settings. Nkarta’s engineering process enhances the natural ability of NK cells to fight disease by identifying and eliminating unhealthy cells, including malfunctioning B cells at the root of many autoimmune conditions. Our lead NK cell therapy candidate, NKX019, uses NK cells collected from healthy donors rather than burdening the patient with a blood collection. Using donor-derived cells allows us to develop CAR NK cells off the shelf and on demand. Nkarta is a people-driven company looking for passionate, collaborative, determined team members galvanized by a paradigm-shifting opportunity to change the cell therapy landscape.   Overview The Director of Clinical Trial Operations works closely with the Executive Director of Clinical Operations and the clinical and leadership teams to lead the strategic planning, execution, and delivery of one or more clinical trials or programs.
