South San Francisco, CA

Associate Scientist/Scientist

The ideal candidate is a self-motivated, energetic, and detail-oriented Ph.D with significant exposure to immunology and oncology research or significant prior experience within a fast-paced Research & Development (R&D) team. The primary role for the candidate is to define immunological and biological mechanisms of action for discovery stage targets and drug candidates and to enact preclinical methodologies to advance the understanding and direction of clinical stage programs. In line with these goals, the successful candidate will employ methodologies that span immunology, biochemistry, and molecular biology to effectively execute in vitro and in vivo experiments. She/he/they will support projects from early development and will have the opportunity to work in a cross functional environment, interacting with discovery, chemistry, and clinical teams, and participating in IND-enabling activities. The candidate must be driven, resourceful, and able to work independently. The candidate will utilize excellent organizational skills and leverage their previous experience to thoughtfully formulate hypotheses, address these hypotheses through experimentation, and present organized data and conclusions to the company. Teamwork, collaboration with colleagues across disciplines, and communication skills are critical. The position will report to our Senior Scientist and Program Leader, Immunology and in vivo Biology.


(not limited to the below and may evolve over time and change depending on business needs and individual expertise): 

  • Work with manager and team to synthesize direction of projects, formulate hypotheses, and carry out experiments with diligence to obtain reproducible results. 
  • Apply routine in vivo and in vitro immune and cellular assays (ELISA, Luminex, western blots, flow cytometry, etc.) to enable drug candidate evaluation to understand mechanism of action.
  • Process and utilize tissue samples from human blood or PBMC and ex vivo murine experiments.
  • Manage outsourced work and communicate effectively with contract research organizations to ensure experimentation is performed accurately with adherence to timelines. 
  • Analyze and interpret data logically to inform project.

About Tempest Therapeutics

Tempest Therapeutics is a clinical-stage oncology company advancing small molecules that combine both targeted and immune-mediated mechanisms with the potential to treat a wide range of tumors.  
The company’s two novel clinical programs are TPST-1495 and TPST-1120, antagonists of EP2/EP4 and PPARα, respectively. Both TPST-1495 and TPST-1120 are advancing through Phase 1 studies designed to study both agents as monotherapies and in combination with other approved agents.  
Tempest is also developing an inhibitor of TREX-1, a double-stranded DNA exonuclease that is designed to control activation of the cGAS/STING pathway, which is an innate immune response pathway that induces the production of IFN-β, a cytokine that is well-established to trigger the development of anti-tumor immunity. Oral delivery of a TREX-1 small molecule inhibitor is intended to selectively activate STING in tumors, leading to anti-tumor immunity.  

Tempest is headquartered in South San Francisco and supported by notable healthcare investors. It is publicly traded on the NASDAQ under the ticker symbol TPST. More information about Tempest can be found on the company’s website at
