Research Associate/Senior Research Associate, In Vivo Pharmacology (RA07-7)



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 a motivated researcher to join our In Vivo Pharmacology team as a Research Associate/Senior Research Associate, supporting the preclinical development of our lead therapeutic TCRs. The ideal candidate should have relevant experience in in vivo pharmacology, mechanism of action and anti-tumor efficacy studies, and enjoy fast-paced, collaborative, and vibrant startup culture. A team player with a sense of urgency will thrive in this role.


  • Participate to in vivo pharmacology efforts and engage in IND-enabling activities.
  • Design and execute in vivo preclinical research focused on anti-tumor efficacy and MOA studies for TScan lead TCR candidates.
  • Perform standard and complex in vivo procedures, such as tumor implantation and measurements (solid or liquid tumor models), multi route dosing, blood sampling, tissue necropsy.
  • Perform standard in vitro and ex vivo work such as cell culture, tumor analysis, flow cytometry, cytokine measurements.
  • Work in a team environment, maintain experimental records, analyze data, and prepare study reports.
  • Candidate must be familiar with IACUC protocols and guidelines.


  • For RA level: BS and 0-3+ years of related experience
  • For Sr. RA level: BS and 3-5+ years of related experience OR MS and 0-2+ years
  • Expertise in in vivo cancer biology, pharmacology, immunology, cell therapy, or related discipline demonstrated by record of relevant scientific achievements
  • Expertise in animal handling, tumor implantation and measurement, blood collection, necropsy required
  • Proficiency with flow cytometry and cell culture preferred
  • Experience isolating PMBCs and T cells, along with experience with functional assays involving primary immune cells (e.g., ELISA, cytotoxicity assays) would be a plus
  • Independent thinker with excellent communication skills

About TScan:

TScan 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.
