About ZymoChem


ZymoChem is breakthrough science for a fossil-free future.  We accelerate the transition to a real-zero economy by developing bio-based materials for everyday products.  Our platform is powered by proprietary carbon conserving (C2) microbes that convert renewable feedstocks into high-value materials while radically minimizing CO2 loss during the production phase.  


ZymoChem recently closed a $21 million Series A round of fundraising to support the launch of our first high-performance material and to advance our first partnered product to commercial scale.  In addition to this funding from premier domestic & international venture capital firms, we are also supported by existing revenues from commercial partnerships with world-leading companies and funding from multiple government awards, including a 2023 $4MM grant from the Department of Energy. 


With a plan to double our team in 2024-25, we seek candidates who are motivated by science & innovation and have a passion to push the boundaries of materials performance.  We are collaborative, multidisciplinary, and relentlessly committed to creating a chemicals, materials, and products industry in tune with the 21st century. 


Our Mission: To catalyze a real-zero economy with drop-in, bio-based solutions.

Our Vision: To live in a world in which the goods we depend on every day are bio-manufactured from 100% renewable materials and designed for a sustainable economy - without compromise.

Our Values: Lead with Compassion, Aspire Collectively, Evolve Continuously, Innovate with Impact, Scale Sustainably

  • Effective multitasking and prioritization skills and an adept ability to improvise work plans while maintaining efficiency
  • Rigorous attention to details with experimental design, execution, noise/variability, reproducibility, and record keeping; and strong computer skills (Google Suite, Microsoft Office, Microsoft Project, etc.)
  • Proficient in the writing of protocols, and in providing internal presentations.
  • Ability to exercise judgment within specifically defined practices and procedures; guided decision making.
  • Ability to incorporate safety concepts in processes and equipment design
  • Must be able to move up to 25 pounds and move around the lab facility between multiple locations.
  • Department specific requirements: 
    • Expertise in polymer synthesis & curing along with the production & processing handling of polymeric materials
    • Experience in designing and carrying out bench-level and/or pilot-level scale-up of polymer production and processing
    • Previous experiences with surface functionalization, crosslinking and/or modification is highly desirable
    • Direct experience working with and exposure to R&D associated with bio-based polymers, hydrogel, super absorbent and/or water-soluble polymers; experience with microbial production of polymers
    • Broad knowledge base of the state of the art and relevant IP landscape
