Pionyr Immunotherapeutics Inc. is an immuno-oncology company based in South San Francisco focused on novel approaches to cancer immunotherapy. We are looking for a highly motivated and dedicated individualfor a full-time Associate Scientist position whowill be dedicated to developing tissue-based technologies to enable translational biomarkerstrategies that helpdrive clinical and discovery programs at Pionyr. The candidate will also help overseeand manage CRO-based projects for CAP-CLIAIHC assay development and validation.The ideal candidate will possess in-depth experience in validating immunohistochemistry (IHC) and multiplexed immunofluorescence assays, antibodies, and tissue-based transcriptomics. He/she will also have strong communication skills, ability to work in a fast-paced environment and a commitment to excellence.

Specific Responsibilities Include(but not limited to):

  • Design, develop, and execute translational immunohistochemistry (IHC) and multiplexed IHC assays to support patient stratification, pharmacodynamics, toxicology, mechanism of actionstudies for the therapeutic drugs, and prediction of clinical response from early discovery to first in human proof of concept.
  • •Develop and execute tissue-based experiments, including optimization and validation of novelantibodies, in preclinical human and mouse models.
  • Staining tissues from various species with different methods including H&E, special stains, Immunohistochemistry (IHC), Immunofluorescence (IF), and In Situ Hybridization (ISH and FISH).
  • Image, analyze, andscoretissue sections, including mouse tissues and human FFPE blocks and Tissue Microarrays (TMAs).
  • Overseeand manage CRO-based projects for CAP-CLIAIHC assay development and validation.
