About eXoZymes

eXoZymes Inc. (NASDAQ: EXOZ) is a Monrovia, CA–based biotechnology company developing AI-enhanced enzymes - exozymes - to produce high-value nutraceutical and pharmaceutical ingredients from sustainable feedstocks. Our proprietary cell-free biocatalysis platform enables the conversion of low-cost inputs into bioactive compounds at near theoretical yields, providing a scalable and environmentally friendly alternative to conventional methods of producing or extracting chemicals.

Backed by public-market capital, private investment, and multi-million-dollar government grants, eXoZymes is expanding its platform, products, and team as we build the next generation of sustainable biomanufacturing technologies.

Position and Scope

We are seeking an experienced process engineer or process chemist with a background in process chemistry, chemical manufacturing, organic isolation chemistry or chemical engineering, to join our team. This person will support the development, scale, and transfer of processes to manufacture nutraceutical and pharmaceutical ingredients via our enzymatic cell-free platform. This role bridges R&D and GMP manufacturing by translating laboratory-scale processes into robust, scalable, and compliant cell-free enzymatic manufacturing processes. The ideal candidate will be an experienced chemical engineer and/or chemist who is familiar with reaction engineering, small-molecule isolation, process design, scale-up and technology transfer. The position is full-time and located in Monrovia, CA.
