Director, Manufacturing Science and Technology

About Us**…**

Obsidian Therapeutics is pioneering engineered cell and gene therapies to deliver transformative outcomes for patients. Obsidian’s programs apply our cytoDRiVE® 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 for the treatment of patients with metastatic melanoma and non-small cell lung cancer.

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/Senior 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 late-stage development through PPQ and lifecycle management. As the primary technical anchor between Process Development, Manufacturing, 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.

As a member of our Technical Operations team, you will be a vital part of a highly collaborative group working to unlock the promise of precision cell therapy for patients, starting with our lead program amsoki-cel (OBX-115), a novel engineered tumor-infiltrating lymphocyte (TIL) cell therapy that uses our proprietary cytoDRiVE® platform. This is a unique opportunity to be a valuable contributor in a well-funded clinical company with field-leading advisors, best-in-class partners, and an experienced team. 

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