Accelerating and scaling immune cell engineering

Effective application of innovative technology in biological research requires a collaborative and cross-disciplinary mindset.

We are a diverse group of engineers, scientists, and synthetic biologists dedicated to empowering our Discovery and Development organizations through design and deployment of state-of-the-art computational and biological tools.

Scientist, Binder Discovery (22004-B-690-MBIO)

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.

We are seeking a Scientist to join ArsenalBio’s Binder Discovery team and lead efforts in generating antibody binders for engineered synthetic receptors and developing new technologies & capabilities as a part of our efforts to develop and commercialize curative immune cell therapies. 

What You Will Do:

  • Perform binder selection campaigns against protein targets from large synthetic libraries.
  • Characterize binder candidates via ELISA, flow cytometry and/or other in vitro assays.
  • Maintain an electronic lab notebook, ensuring experimental methods and results are recorded timely, accurately, and consistently.
  • Manage own work to accomplish assigned objectives.
  • Under the direction of a manager, execute high-quality, well-controlled experiments. 
  • Summarize experimental results and review conclusions with project leaders. 
  • Communicate with project leads about project status, significant findings, or critical problem areas.

  • What Will You Bring:

  • Ph.D. in molecular biology, protein engineering, or a related discipline with 0-2 yrs industry experience, or Masters with 5+ years experience, or Bachelor with 7 + years experience.
  • Direct experience with in vitro protein display systems (e.g. yeast, mammalian, or phage display) is required.
  • Hands-on experience with basic techniques in molecular biology and mammalian cell culture.
  • Excellent organizational, written and verbal communication and interpersonal skills
  • Strong analytical ability with excellent attention to detail. 
  • Ability to recognize and resolve basic problems encountered in standard procedures.
  • Ability to quickly learn new skills and knowledge on the job, demonstrate productivity and deliver high-quality results.
  • Being self-sufficient but also contributing actively as a team player.

  • Preferred Skills:

  • Working knowledge and experience of antibody characterization methods, including BLI (Forte-Bio Octet), SPR, flow cytometry, are desired.
  • Working experience of antibody library design and construction.
  • Working knowledge of NGS technologies and workflows.
  • Working knowledge of high-throughput antibody selection (e.g. semi-automated panning on the Kingfisher system) and high throughput screening processes.
  • Experience in performing data analysis with R/Python, FlowJo, Prism, etc., is a plus.

  • 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.
