Join Our Team
Principal Scientist, Analytical Development
Obsidian Therapeutics is pioneering engineered cell and gene therapies to deliver transformative outcomes for patients. Obsidian’s programs apply our CytoDriveTM technology in Cell and Gene therapy products to control expression of proteins for enhanced therapeutic efficacy and safety. Obsidian’s lead program is currently in clinical development. We recently received our IND clearance from FDA to begin our first clinical trial for the treatment of patients with metastatic melanoma.
We’re proud of our diverse talented team and committed to cultivating an environment of inclusion where each person feels a strong sense of belonging and is supported to continuously learn and contribute their best work. Our research team is based in the heart of Cambridge, MA, and our Technical Development, Manufacturing & Quality team is based in our brand new facility in Bedford, MA to support our growth. Obsidianites enjoy a highly collaborative culture, competitive salary and benefits, and potential for ownership through stock options.
The Principal Scientist, Analytical Development is a key role within our Technical Development and Manufacturing group and will be responsible for leading a team within Analytical Development. We’re looking for a leader to contribute to building Obsidian’s analytical sciences capabilities for process and product characterization, driving the development of the first autologous cell therapy product in our pipeline targeting cancer. You’ll work collaboratively with the Analytical Development team as well as Manufacturing, Process Development, Regulatory, and Quality functions to develop analytical tools for the characterization of viral vectors and cell therapy products to support our clinical pipeline. As part of our Technical Development and Manufacturing department, you’ll be a vital part of working to achieve Obsidian’s vision by collaboratively translating innovative science into medical breakthroughs for patients, starting with our lead program cytoTIL15 engineered to make TILs more effective for more patients.
This is a unique opportunity to be a contributor in a well-funded pre-clinical company with blue chip investors, field-leading advisors, best-in-class partners (BMS, Vertex, MD Anderson), and an experienced team. You'll help us build a dynamic, innovative, passionate, collaborative, and successful organization focused on delivering transformative therapies in areas of greatest clinical need.
