Our Opportunity...

We are looking for a highly motivated Scientist, Viral Vector Analytical Development, with a strong background in viral vector analytical development and/or quality control. As a key contributor within our Viral Vector Analytical Development team, you’ll support analytical testing for process characterization and product characterization helping to drive the development of our first clinical stage autologous cell therapy program targeting solid tumors.

You’ll work collaboratively with the Sample Testing Core, Process Development, and Quality functions to develop analytical tools and test process characterization samples for viral vectors and associated cell therapy products to support our clinical pipeline. As a member of our Technical Operations department, you will be a vital part of a highly collaborative team working to achieve Obsidian’s vision by collaboratively 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 lab-based role; work is full-time on-site in our Bedford, MA location.
