The Role

We are seeking an experienced and motivated Associate Scientist to join the Bioassay team as a part of our Therapeutic Proteins Department. Our group’s focus is to develop assays to interrogate regulation of molecular function and signaling which contributes to the therapeutic mechanism of action and we play an integral role in discovery and characterization of therapeutic molecules across diverse disease areas.

  • Exhibit flexibility with changing priorities and can effectively manage multiple projects

Experience with mammalian cell culture, cell engineering and validation, and cell-based assay development are required. Experience with flow cytometry is strongly preferred.
