Senior/Principal Scientist, Cell Process Development (SC06-1)



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 Senior/Principal Scientist in Cellular Process Development to drive innovative efforts in building clinical manufacturing processes for the company’s novel non-viral engineered TCR-T cell therapy products. This newly created role will reside within the Technical Development & Manufacturing Team and will report to the Senior Director of Process Development.  Key activities will include the bench-scale feasibility studies, process scale-up and optimization, IND-enabling activities, and the tech transfer to clinical manufacturing, amongst others.

The ideal candidate will (i) have a strong background in cellular bioprocessing and a firm understanding of the cGMPs and ICH guidelines related to the manufacture of human cell and gene therapies; (ii) be a steadfast problem solver who is energized by a fast-paced, lean, and agile environment; and (iii) be a team player who can foster productive relationships with internal colleagues and with external partners.

The candidate should be well-versed in a variety of state-of-the-art cell processing instrumentation including processing of apheresis products, target cell isolation platforms, automated cell washing, controlled rate freezing systems, cell expansion and cryopreservation.  Experience with non-viral delivery modalities such as electroporation, mechanoporation, microfluidics, and a background in novel instrument development are highly desired attributes. 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.


  • Responsible for the design, execution, and interpretation of experimental studies
  • Develop, optimize and scale up a robust cell manufacturing process to support IND enabling studies and GMP manufacturing
  • Act as primary SME for all process development and process instrumentation engineering activities
  • Author and review of technical documentation to support early-stage activities (development reports and supporting documentation for regulatory filings) as well as draft manufacturing documentation to support tech transfer
  • Collaborate closely with manufacturing to tech transfer the developed process to a GMP facility and act as SME during training/process shake-down runs


  • PhD with 5+ years of relevant industry experience. Degree emphasis in biological sciences, biomedical/chemical engineering or related field is preferred
  • Background developing manufacturing strategies for human primary T cell products is preferred, with focus on the building of functionally closed processes
  • Experience in the development/engineering of novel cell processing and/or microfluidic-based instrumentation is highly desired
  • Scientific creativity, critical thinking, ability to innovate, and analytical problem solving
  • Excellent communication skills (both written and oral)
  • Experience drafting manufacturing documentation and supporting documentation for regulatory filings
