RAPT Therapeutics is a clinical stage immunology-based biopharmaceutical company focused on discovering, developing, and commercializing oral small molecule therapies for patients with significant unmet needs in oncology and inflammatory diseases. Utilizing its proprietary discovery and development engine, the Company is developing highly selective small molecules designed to modulate the critical immune drivers underlying these diseases. RAPT has discovered and advanced two unique drug candidates, FLX475 and RPT193, each targeting C-C motif chemokine receptor 4 (CCR4), for the treatment of cancer and inflammation, respectively. The Company is also pursuing a range of targets, including hematopoietic progenitor kinase 1 (HPK1) that are in the discovery stage of development.


We are seeking a highly motivated and creative research associate with expertise in tumor immunology and/or inflammation. The selected candidate will be expected to perform at a high level working with a tight-knit team to support RAPT research efforts to identify and develop cutting edge immune-based therapies for the treatment of cancer and inflammatory diseases.  This position directly reports to the Senior Vivarium Manager.
