Principal Research Associate/Associate Scientist (RA05-6)



TScan Therapeutics is a startup biotech seeking to revolutionize life-changing therapeutics for patients by identifying novel T cells and epitopes. We are looking for an experienced researcher to join our team as Principal Research Associate/ Scientist, supporting our novel TCR discovery and validation workflow in house. The ideal candidate should have relevant experience in T cell immunology, primary and tumor cell culture, cell-based assays, and flow cytometry, and enjoy fast-paced, collaborative and vibrant startup culture. A team player with a sense of urgency will thrive in this role.


T-Scan Therapeutics was founded in 2018 by a small group of scientists led by Dr. Stephen Elledge (Harvard Medical School/HHMI). TScan is discovering and developing novel TCR-engineered T cell therapies for the treatment of cancer. TScan’s discovery platform is centered around a breakthrough technology that enables the rapid, comprehensive, and genome-wide identification of the peptide antigen targets of T cell receptors. This technology greatly enhances our ability to understand the specific antigens that drive important disease processes, including tumor cell recognition by the immune system, self-reactivity in autoimmune disorders, and acquired immunity in infectious disease. TScan is using the platform in oncology to discover new TCR/target pairs and to rapidly move novel TCRs into clinical development.


  • Evaluate and nominate candidate TCRs discovered from TScan’s TCR discovery screens for preclinical development.
  • Engineer T cells to express TCRs of interest and analyze TCR expression by flow cytometry.
  • Lead development and execution of T cell functional assays (cytotoxicity, cytokine production, proliferation).
  • Perform extensive literature search to find the appropriate tumor cell lines to be used in functional assays.
  • Engineer cancer cell lines to express or knock out target antigen and maintain them.
  • Isolate human PBMCs from Leukopaks.
  • Maintain detailed records of experiments, analyze and compile data, and present in group and company meetings.


  • Ph.D. with 0-1 year of relevant post-doc, biopharmaceutical or biotechnology industry experience, or B.S./M.S. with 8-10 years relevant experience.
  • Proficiency in tissue culture, immune cell isolation and flow cytometry required. Experience with ELISA and cytotoxicity assays using IncuCyte desired.
  • Experience in T cell immunology desired; understanding of cancer biology and molecular biology a plus.
  • Excellent communication skills (both written and oral), ability to work in a matrix environment and experience presenting in team meetings.
  • Enthusiasm and willingness to learn new concepts, new techniques, participate in Journal club and work in a fast-paced environment.
