Director/Senior Director, Antibody Engineering & Drug Discovery

About the Company:

Dren Bio (the "Company") is a privately held, clinical stage biopharmaceutical company focused on developing therapeutic antibodies for the treatment of cancer, autoimmune and other serious diseases. The Company's management team and scientific advisors have profound expertise covering the discovery and development of engineered antibodies designed to selectively target and deplete pathological cells. Dren Bio's pipeline is currently comprised of two distinct drug discovery programs. The Company's first program surrounds DR-01, its lead product candidate, which induces antibody-mediated killing of a cell type that is responsible for a multitude of hematologic malignancies and plays a key role in various autoimmune diseases. The Company's second program surrounds its Targeted Myeloid Engager and Phagocytosis Platform, a proprietary bispecific antibody-based technology that provides a novel mechanism of action to selectively engage myeloid cells for (1) targeted depletion of pathologic cells and other disease-inducing agents and (2) inducing localized immunostimulation. The engagement of antigen presenting cells has the potential to elicit a sustained, durable response.


Biologics Discovery


Director/ Senior Director


Foster City, CA

About the Opportunity:

Dren Bio is seeking a highly qualified expert in antibody engineering & drug discovery to lead the Biologics Group. The Biologics group is responsible for various functions critical for drug development such as: antibody discovery, molecular biology, cell line engineering, protein engineering, biophysical analytics, and functional cell assays. This position will need to bridge expertise in protein/antibody engineering and biology to drive projects from early exploratory work to clinical POC for the myeloid engager platform working collaboratively with other functional team leaders at Dren.

Role and Responsibilities:
  • Lead efforts in antibody development, antibody engineering, bispecific and multi-domain antibodies for therapeutic programs at Dren Bio

  • Utilize multiple strategies for antibody discovery such as hybridoma screening, B-cell screening, phage display to select and optimize top antibody candidates for affinity and other properties

  • Design and execute protein engineering strategies to deliver developable biologics formats by applying molecular biology, structure-guided, computational, combinatorial/display approaches

  • Lead and mentor an antibody engineering and molecular biology team of scientists responsible for designing, generating, and characterizing antibody and bi/multi-specific antibody based therapeutics

  • As a key member of Dren's cross-functional drug discovery team collaborate with immunology, process sciences, preclinical pharmacology teams to expand and advance the pipeline of candidates from Dren’s myeloid engager platform
