Senior Research Associate/Principal Research Associate (RA05-4)



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 Senior/Principal Research Associate, supporting our novel target identification and validation workflow in house. The ideal candidate should have relevant experience in T cell immunology, cancer cell culture and molecular biology, and enjoy fast-paced, collaborative, and vibrant startup culture. A team player with a willingness to learn 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.


  • Engage and innovate on large-scale in vitro immune cell screening efforts to discover novel TCRs to fuel our therapeutic pipeline.
  • Isolate PBMC and primary T cells and monocytes from blood products such as leukopaks.
  • Engineer cancer cell lines with lentiviruses, culture and maintain cancer cell lines.
  • Assist in performing immune cell assays such as tumor cell killing, cytokine production and T cell proliferation.
  • Candidate to analyze data and present and group and company meetings.


  • B.S./ M.S. with 3-5 years of experience in biopharmaceutical or biotechnology industry experience.
  • Extensive experience in T cell immunology required, understanding of dendritic cell biology, cancer biology and molecular biology a plus.
  • Proficiency in tissue culture and flow cytometry is essential, experience with ELISA and cytotoxicity assays using Incucyte desired.
  • Excellent communication skills (both written and oral) and ability to work in a matrix environment. Experience presenting in team meetings a plus.
  • Enthusiasm and willingness to learn new techniques and work in a fast-paced environment
