Principal Scientist, Analytical Development

About Artiva:We are a clinical-stage biotechnology company focused on developing natural killer (NK) cell-based therapies. Our mission is to develop effective, safe, and accessible cell therapies for patients with devastating autoimmune diseases. We aim to develop therapies that patients and physicians can utilize in a community setting. Our lead product candidate, AlloNK, is a non-genetically modified, cryopreserved NK cell therapy being evaluated in combination with B-cell targeted monoclonal antibodies (mAbs). We believe the compelling cell killing properties of NK cells, when combined with mAbs for targeting, creates an opportunity to generate potentially transformative therapies.For more information, visit .Job Summary:The incumbent will lead and set the strategic direction for the cell potency analytical development team to develop and optimize cell-based assays to support the characterization and release of our allogeneic, natural killer (NK) cell-based therapies. In this role, the incumbent will serve as the scientific subject matter expert for cell potency, defining the assay development strategy and directing the evaluation and development of new cell potency assay methods and product characterization for NK cell products. This role includes leading and mentoring a team of scientists and analysts within the cell potency group, providing scientific oversight of benchtop assay development, detailed documentation of methods and materials, authoring and reviewing SOPs/reports and communicating findings to the wider organization. This role will collaborate closely with R&D and Process Development teams to identify product attributes that advance optimal product development and assess function. They will also oversee/participate in assay optimizations, standardizations, and transfers to QC labs.
