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, Immunology (2234-N-670-IMM)

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. 

Our people are our greatest asset, they bring scientific talents in molecular biology, immunology, pharmacology, protein chemistry, computational biology, automation, genome engineering, software and other fields to make the future happen now.

ArsenalBio is seeking a talented and driven Scientist/Senior Scientist to join our Immunology team as part of our effort to develop best in class cell therapies for solid tumors. This candidate will be responsible for executing immunological experiments to identify and prioritize novel genetic perturbations to improve the therapeutic activity of reprogrammed T cells.   

What You Will Do:

  • Design and execute immunological experiments characterizing gene edited human T cells 
  • Document experiments, interpret data and communicate results to drive decision making
  • Collaborate with NGS, Computational Biology, Synthetic Biology and other functional groups to drive success of cross functional discovery projects.

  • What Will You Bring:

  • PhD in Immunology, Molecular/Cell Biology, or a related discipline; or Masters  with 5+ years experience; or  Bachelors with 7+ years experience
  • Hands-on experience with primary immune cell culture, preferably with murine/human T cells
  • Experience performing T cell functional assays (T and tumor cell co-cultures, T cell cytotoxicity assays, etc.) is strongly preferred 
  • Familiarity with one or more of the following is preferred: multicolor flow cytometry (cell surface phenotyping, intracellular cytokine staining, phosphoflow), viral or non-viral T cell editing (e.g. generation of gene KO human T cells via CRISPR/Cas9), standard molecular biology assays (RNA/DNA extraction, etc.)
  • Experience with pooled or arrayed CRISPR screens in primary human T cells is a plus
  • Excellent organizational, written and verbal communication and interpersonal skills
  • Ability to quickly learn new skills and knowledge on the job, demonstrate productivity, and deliver high-quality results
  • Experience performing data analysis with FlowJo, Prism, etc., R/Python or other data language is a plus 
  • Ability to multitask as needed in a start-up environment

  • ArsenalBio prioritizes the providing of a safe and healthy workplace that is consistent with COVID-19 public health guidance and legal requirements.  In order to protect our employees and visitors, we require all visitors (including candidates) and employees to present proof of being fully vaccinated against COVID-19 when coming onsite.

    We are committed to hiring the best talent from diverse backgrounds. A diverse workforce engenders richness of thought, creativity, and discovery. We invite individuals who embrace intellectual achievement to bring their unique personal and professional journeys and together we will build transformative cell therapies for cancer patients.

    We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.

    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.
    This is our Company.
