The Biology department at Calithera Biosciences is seeking a highly motivated individual for our group who has experience with in vitro cellular and biochemical assays. This position will be responsible for the design, execution, and interpretation of experiments to advance new and existing preclinical programs.

Company Background

Calithera is focused on discovering and developing small molecule drugs that slow tumor growth through controlling key metabolic pathways in the tumor and immune cells.

Tumor metabolism and tumor immunology are promising new interrelated fields for cancer drug discovery. Recent clinical successes have demonstrated the potential to slow abnormal cell growth and create fundamentally new therapies for cancer patients. Our investigational onco-metabolism medicines take advantage of the specific metabolic requirements of tumor cells and cancer-fighting immune cells.

Calithera’s discovery and development efforts are focused on diseases for which new treatments are urgently needed, for patients suffering from renal cell carcinoma, triple negative breast cancer and other tumor types.
