Cellcraft® is a B2B cultivated meat company based in Cambridge tackling global food security and sustainability challenges. Our AI-driven bioelectronic technology powers the Cellcraft® Farm: an end-to-end, scalable Cultivated Meat (CM) Manufacturing Platform to empower food producers to make their own delectable, sustainable cultivated meats locally. Cellcraft is the world’s first cultivated meat company with a focus on software and analytics. We believe the future of meat must be both sustainable and irresistible.

As a Bioprocess Engineer, you will play a key role in developing, optimising, and scaling bioreactor-based processes for cultivated meat production. You will be adaptable and able to handle a range of cross-functional projects in other functional areas including cell line and media development, assay development, and downstream processing, to ensure robust, efficient, and scalable production systems.

Cellcraft is a fast-paced environment. You must be a problem solver capable of applying initiative who enjoys seeing their ideas come to fruition.
