Scientist / Senior Scientist, Analytical 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 Scientist / Sr. Scientist in Cellular Analytical Development lead efforts in developing test methods for the company’s novel TCR-engineered T cell therapy products. This newly created role will reside within the Technical Development & Manufacturing Team and will report to the Senior Director of Cell Process Development. Key activities will include the development of analytical methods to support cellular product process development, process scale-up and optimization, IND-enabling activities, and the tech transfer of in-process, release, and stability-indicating assay methods to QC, amongst others.

The ideal candidate will (i) have a strong background in cellular analytics and a firm understanding of the cGMPs and ICH guidelines related to the manufacture and testing of human cell and gene therapy products; (ii) be a steadfast problem solver who will thrive in 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 cell-based, molecular, and analyte-based testing including, but not limited to, live/dead assays, cell enumeration, flow cytometry, fluorescence microscopy, fluorimetry, ddPCR / qPCR, and ELISA. Experience with DoE-based experimental design and execution, interpretation of next-generation sequencing data, LC-MS, UPLC are desired. Experience with high-throughput protein / analyte analysis systems are a plus.


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 analytical readouts on TCR-engineered T cell processes and products
  • Be a focal point for analytical best practices, suitable for GMP testing, within the organization and introduce these concepts to a research-focused startup
  • Develop, optimize and qualify test methods to support IND enabling studies, GMP manufacturing, release and stability testing of T-Scan’s cellular drug products.
  • Integrate with the process development function to implement process improvements based on analytical output
  • Act as primary SME for tech transfer for all optimized / qualified methods to QC and assist quality in developing testing strategies and validation efforts
  • Author and review of technical documentation to support early stage activities (development reports and supporting documentation for regulatory filings) as well as draft QC documentation to support tech transfer


  • PhD with 3+ years of relevant industry experience. Degree emphasis in cell biology, immunology, biological sciences, biomedical/chemical engineering or related field is preferred.
  • Experience developing test strategies for cell-based therapies is preferred, with focus on process characterization, immunophenotyping, and cell-based potency and toxicity assays.
  • Scientific creativity, critical thinking, ability to innovate, and analytical problem solving.
  • Excellent communication skills (both written and oral) is critical.
  • Experience drafting SOPs and testing documentation as well as supporting documentation for regulatory filings is strongly desired.
  • Experience in the development and implementation of phase appropriate and novel approaches to potency assays is desirable.
