Caribou Biosciences, Inc. is a leading clinical-stage CRISPR genome editing biotechnology company located in Berkeley, CA. Caribou's tools and technologies provide transformative capabilities to therapeutic development and the company is advancing an internal pipeline of genome-edited cell therapies for various oncology indications. Caribou was founded in 2011 by CRISPR pioneers including Nobel Prize winner Jennifer Doudna, PhD, Martin Jinek, PhD, and Rachel Haurwitz, PhD, our President and CEO. The company has developed a novel CRISPR genome editing technology platform and has a leading intellectual property position.


At Caribou, every employee is valued for their unique perspective, background, and diversity. Every person on the Caribou team contributes to problem solving and innovation. The Company’s vision is to advance agile genome editing innovations for the benefit of our communities.

Our fun and collaborative Process Development Team is seeking an innovative and highly motivated Scientist to help optimize the platform manufacturing process for Caribou’s gene-edited cell therapies.  Reporting to the VP of Technical Operations, you will have the opportunity to solve the challenges that come with our team’s goal of improving the cell therapy manufacturing process from upstream to downstream.  Partnering with our PD Engineers and Associates, you will evaluate new technologies, reagents and gene-delivery techniques.  Your solutions will quickly be implemented into the manufacturing process, and have a direct impact on trials.  You will have the opportunity to gain experience with multiple aspects of cell therapy clinical development.  This includes the participation in technical transfer of manufacturing processes to Contract Manufacturing Organizations (CMOs). Serving as a cell therapy manufacturing subject matter expert, you will also help manage GMP manufacturing of clinical trial materials including batch record review, and manufacturing oversight and impact assessments on Deviations, Investigations, CAPAs, and Change Controls related to the manufacturing process.
