Bold ideas. Reliable data. World-Class Science.

Designing therapies to cure our most important health challenges requires the audacity to advance a bold idea and explore new biologies with world-class science.

By pushing at the frontiers of science, challenging what we think we know, and holding ourselves to the highest standards of irrefutable proof, we are reshaping the future of curative cellular therapies.

Scientist/Senior Scientist, Discovery Immunology

ArsenalBio’s mission is to develop efficacious and safe cellular therapies for patients with chronic diseases, initially cancer.  Our products are being designed to herald the transition of adoptive cell therapy from a hospital based treatment to outpatient therapy, like most other cancer treatments.

We are seeking an outstanding Scientist/Senior Scientist to lead immunology discovery efforts to develop next generation CAR T cellular therapies for cancer. They will have a background in immunology, cellular or cancer biology and have the creativity to present new ideas and solve challenging problems. The successful candidate will communicate and collaborate within and across disciplines, both internally and with outside partners, including pharmaceutical partners and leading academic labs. This role is ideal for an individual who is driven and passionate about cell therapy in a fast-paced collaborative environment.

What You Will Do:

  • Design, develop, and execute a broad range of cell based functional and phenotypic in vitro assays to identify mechanisms of T cell dysfunction in solid tumors
  • Conduct assay design and execute experiments to support selection of lead candidates for engineered T cell pipeline programs
  • Design and execute in vitro and in vivo studies to elucidate mechanism of action and biomarkers of response/resistance for therapeutic candidates
  • Drive scientific and technical innovation collaboratively with other members of ArsenalBio
  • Summarize and synthesize data across experiments and present findings at all levels of the organization
  • Provide exceptional scientific leadership and mentorship to scientists and research associates

  • Strong background in immunology and/or tumor-immune cell interactions, with a focus on T cell biology and direct experience with primary immune cell culture; prior experience with genetic engineering of primary immune cells and knowledge of tumor microenvironment (TME) and cytokine signaling is preferred
  • Expertise in developing and executing in vitro cellular assays including immune cell phenotyping, cytotoxicity, proliferation, 3D cultures and cytokine analysis
  • Outstanding written and oral communication skills and the ability to organize and communicate complex data sets in a clear and concise manner to key stakeholders from diverse backgrounds 
  • Ability to multi-task and work in collaboration with peers within a fast-paced team environment with a positive outlook and high degree of self-motivation and organization

    ArsenalBio was formed by its investors and scientific founders to discover, develop and commercialize curative and safe cellular therapies for patients with life threatening diseases, initially cancer.

    We believe the most productive and secure route to achieving this goal is to build scaled platforms of technologies challenged with scientific questions to yield informative data from hypothesis driven, well controlled experiments. These data will inform the design of ambitious, best-in-class, lead compositions. Our leads will be rigorously evaluated and honed until we are convinced our matured leads, called development candidates, can be prepared for testing in needy, and vulnerable patients.

    Our products will be designed to speed the transition of cell therapy from hospital-based to outpatient treatments, increasing access to more patients at lower cost to patients, health systems, and insurers.

    To achieve this mission, we are building diverse teams of talented, curious, and caring individuals who believe in our mission and our vision to be sustainable in our business plan, our work habits, and our personal lives.

    Our values create: a foundation for mutual respect, an engaging harmony from many voices, and unselfish behavior to aid our colleagues.

    This is ArsenalBio.
