Careers

Senior Scientist, Protein Mass Spectrometry

Harpoon Therapeutics is a clinical-stage immunotherapy company located in South San Francisco. The company is developing novel biologics that harness the power of the body’s immune system to treat patients suffering from cancer and other diseases. Using its proprietary Tri-specific T cell Activating Construct (TriTAC®) platform, Harpoon is developing a pipeline of novel T cell engagers initially focused on the treatment of solid tumors and hematologic malignancies. HPN424 targets PSMA and is in a Phase 1/2a trial for metastatic castration-resistant prostate cancer. HPN536 targets mesothelin and is in a Phase 1/2a trial for cancers expressing mesothelin, initially focused on ovarian, pancreatic cancers and mesothelioma. HPN217 targets BCMA and is in a Phase 1/2 trial for relapsed, refractory multiple myeloma. HPN328 targets DLL3 and is in a Phase 1/2 trial for small cell lung cancer and other DLL3-expressing tumors. Harpoon has also developed a proprietary ProTriTAC™ platform, which applies a prodrug concept to its TriTAC platform to create a therapeutic T cell engager that remains inactive until it reaches the tumor microenvironment. Harpoon is led by an experienced management team. The company emphasizes a collegial, collaborative environment and has a strong record of scientific innovation, pioneering protein engineering, expertise in tumor immunology and pre-clinical and clinical research.
