Scientist – eXoZymes Inc. (Monrovia, CA)

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 feed stocks. 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.

We are seeking an experienced scientist with an engineering mindset/or an engineer with scientific curiosity and grounding; and a background in biochemistry, chemical biology, or chemical/biological engineering or related fields to join our team developing nutraceutical and pharmaceutical ingredients via our enzymatic cell-free systems. The ideal candidate combines hands-on experience in enzymatic biocatalysis and reaction optimization with an empirical, systematic approach to translate new product innovation from bench-scale results into scalable manufacturing processes.

The position is full-time and located in Monrovia, CA.

• Collaborate cross-functionally to design, assemble, and optimize cell-free, multi-enzyme pathways and biocatalytic reaction systems from bench through early process scale, targeting specifications for yield, purity, and activity.
• Develop and execute biochemical assays to characterize enzyme kinetics, stability, and selectivity; independently evaluate purified proteins and enzyme variants and interpret results to drive project decisions.
• Apply disciplined experimental approaches (e.g., DoE) to develop robust, cost-efficient biosolutions from prototype through technology transfer to manufacturing.

• Establish robust, reproducible biocatalyst test methods that generate reliable, comparable data independent of experiment, operator, or time.
• Define clear, data-driven acceptance criteria that translate experimental results into actionable go/no-go decisions across enzyme candidates and unit operations.
• Develop and improve assay and screening platforms to advance throughput, sensitivity, and scalability for enzyme characterization and variant selection.

• Systematic, methodical approach to translating preliminary results into a robust process through structured multivariate optimization and data-driven experimental iteration.
• Partner with process development engineers to support scale-up of biocatalytic and cell-free reactions from bench to the 1–100 L range, identifying and resolving technical challenges at each scale transition.
• Contribute to development and optimization of downstream isolation and purification methods for small molecules from complex biocatalytic mixtures, with attention to yield, purity, and scalability.
• Build mechanistic and empirical models to support scale translation and third-party technology transfer.

• Education:
  • PhD in biochemistry, chemical biology, chemical/biological engineering, or a closely related field, with 3–5 years of relevant industry or postdoctoral experience.
    OR
  • MS in one of these fields, with 5 – 8 years of industry experience.
• Demonstrated ability to independently design experiments, troubleshoot complex technical problems, and communicate findings clearly to cross-functional teams.
• Proven track record of rigorous scientific documentation, including peer-reviewed publication, and/or technical reports, SOP development, as well as meticulous laboratory record keeping consistent with industry quality standards.
• Legal authorization to work in the United States on a full-time basis. Visa sponsorship for exceptional candidates may be considered

• Hands-on experience developing biocatalytic or cell-free reaction systems, with working knowledge of engineering and process parameters that govern performance across scales.
• Proficiency with analytical techniques used for protein and small molecule characterization (e.g.,…
