At Bristol Myers Squibb, we are inspired by a single vision – transforming patients’ lives through science. In oncology, hematology, immunology and cardiovascular disease – and one of the most diverse and promising pipelines in the industry – each of our passionate colleagues contribute to innovations that drive meaningful change. We bring a human touch to every treatment we pioneer. Join us and make a difference.

We are seeking a motivated and innovative scientist to join Cell Assay Development (CAD) team within Discovery Biotherapeutics. CAD team serves as an interface between multidisciplinary teams across Protein Science and Biology. This position has a core emphasis on establishing, optimizing and executing essential bio-assays that facilitate functional characterization on antibodies or protein-based therapeutic leads in low to high throughput. The successful candidate is expected to be a good team player that closely interact with research teams from Biology, Antibody Discovery, Automation Technology, Protein Engineering and Recombinant Proteins. In addition to assay development, this candidate will also involve in cell engineering works to generate over-expressed, knock-out or knock-in cell materials.


  • Profile receptor density, signaling pathways and promoter activity on key assay cell lines
  • Validate and optimize existing assay protocols to drive performance
  • Maintain, characterize and curate key cell line materials
  • Support data generation and analysis according to specific projects
  • Survey literatures, patents, commercial kits and transform the information into new workflow for assay use
  • (Occasional) Engineer cell lines to create new functional read-out
