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 Technical Operations team is based in our purpose built facility in Bedford, MA. Obsidianites enjoy a highly collaborative culture, competitive salary and benefits, and potential for ownership through stock options.

Our Opportunity...

We are looking for a highly motivated Director, MSAT, with a strong background in drug development (preferably autologous cell therapy). You’ll serve as the go-to technical leader for manufacturing operations, solving complex problems and translating data into actionable improvements, helping to drive the development of our first clinical stage autologous cell therapy program targeting solid tumors.

You will lead end-to-end MSAT strategy and execution, ensuring seamless progression from early-stage development through PPQ and lifecycle management. As the primary technical anchor between Process Development, Quality, and our external partners, you’ll ensure the manufacturing processes remain robust, compliant, and efficient; drive deviation investigations to root cause, monitor critical process parameters (CPPs) and critical quality attributes (CQAs), and perform data trending and statistical analysis. You’ll be a vital part of a highly collaborative team working to achieve Obsidian’s vision by translating innovative science into medical breakthroughs for patients starting with our lead program OBX-115, a novel engineered tumor-infiltrating lymphocyte (TIL) therapy.

This is a unique opportunity to be a contributor in a well-funded clinical company with blue chip investors, field-leading advisors, best-in-class partners, 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.

This is a Hybrid role based out of our Bedford, MA location.
