Senior Data Scientist

About Pear Bio
At Pear Bio, we are personalizing cancer treatment selection because every cancer is unique. To achieve this, we have developed a test that cultures patient tumor samples and matched immune cells, monitors cell behaviors during therapy exposure, and identifies effective treatments for that patient. This technology acts as a translational model and clinical development tool for drug discovery. Our patient data, biobank and biomarker technology have led to the creation of an in-house drug discovery pipeline for cancers with high unmet need.
We are a VC-backed start-up based in London, England and Natick, Massachusetts. To grow our company, we’re looking for a
