Senior Scientist, Upstream Process Development

The Senior Scientist, Upstream Process Development will play a hands-on role in advancing our novel expression technology by developing, optimizing, and scaling fermentation and cell-culture processes.

This role is for a senior upstream scientist who will help push our novel expression technology to the next level by developing, challenging, and improving fermentation and cell-culture processes through deep scientific thinking, creativity, and hands-on experimentation.

We are looking for an experienced, creative, and persistent upstream Senior Scientist who actively uses literature, engineering judgment, and hands‑on experimentation to solve complex bioprocess challenges.
