Principal Scientist, Viral Vector Process Development

Bedford, MA

About Us…

Obsidian Therapeutics is expanding the reach of TIL therapy. We are pioneering engineered tumor infiltrating lymphocyte (TIL) therapies to deliver transformative outcomes for patients suffering from solid tumor malignancies. Obsidian’s programs apply our cytoDRiVE® platform technology to express regulated therapeutic proteins to enhance anti-tumor activity. We are investigating OBX-115 and enrolling patients in an ongoing multicenter clinical trial in advanced melanoma and non-small cell lung cancer (Agni-01).

We’re proud of our diverse talented team and committed to cultivating an environment 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 facility in Bedford, MA. Obsidianites enjoy a highly collaborative culture, competitive salary and benefits, and potential for ownership through stock options.

In April 2024, we announced closure of an oversubscribed $160.5 million Series C financing with a top-tier syndicate of life science investors to advance Obsidian’s lead program in its ongoing trials.

Our Opportunity…

We’re looking for a highly motivated, collaborative, and experienced scientist with a strong background in viral vector process development and a flexible and creative mindset to help drive the development of our cell therapy products targeting cancer. The successful candidate will lead efforts in process development including process characterization. As part of our Technical Operations team, you will 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.

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 will help us build a dynamic, innovative, passionate, collaborative, and successful organization focused on delivering transformative therapies in areas of greatest clinical need.

You Will…

• Drive the design and execution of experiments for the late-stage development of the cGMP manufacturing process and associated process controls for clinical/commercial supply of viral vectors and associated cell lines/banks.
• Plan, design, execute, and analyze process characterization studies to define critical process parameters and critical quality attributes utilizing statistical design of experiments (DOE) to evaluate process robustness and establish control strategies.
• Compile, organize, and analyze data across multiple experiments to enable process understanding and logical, data-driven decisions.
• Manage and mentor a team of scientists and engineers fostering professional development and technical growth.
• Innovate solutions to address current technical challenges and evaluate/ incorporate next-generation process technologies.
• Lead and support key technology transfer document preparation, technology transfer & implementation of the process, and serve as the technical point of contact for the process development function in assigned projects. Occasional travel will be required.
• Supply development viral vector materials to support research/non-clinical studies, analytical development, and CDMO technology transfer activities.
• Represent process development in CMC sub-teams for assigned projects.
• Author relevant CMC sections in regulatory documents and support responses for regulatory agencies.
• Collaborate closely with internal stakeholders (Analytical Development, Quality Control, Research, Quality Assurance, Regulatory, Project Management) in a fast-paced, rapidly developing environment.
