Senior Process Engineer - Pyrolysis

Charm IndustrialFort Lupton, Colorado, United StatesOnsite
About Charm
Our mission is to return the atmosphere to 280 ppm CO₂. We convert excess inedible biomass into carbon-rich bio-oil and inject it into underground storage for permanent carbon removal. At scale, we can use bio-oil to make fossil-free iron.Our carbon removal efforts began in 2020 with initial purchases from customers like Stripe, Shopify, and Microsoft. Since then, we’ve scaled to

thousands of tons of carbon removal


, grown to over a hundred employees, and established three locations in San Francisco, Colorado, and Kansas. Join us in 2025 as we work toward putting 10,000 tons of carbon back underground!We're expanding our team of ambitious, creative, and hands-on problem solvers. We value psychological safety, collaboration, and continuous learning. We take calculated risks and treat mistakes as opportunities to improve.

About the Role


  • We are seeking a highly experienced Senior Process Engineer to join our pyrolysis engineering team.
  • The ideal candidate will be responsible for designing, optimizing, and implementing pyrolysis process systems, ensuring efficiency, safety, and sustainability.
  • This role requires expertise in thermal decomposition, fluidization engineering, and process scale-up.
  • This role will work closely with a cross-functional team to iteratively improve the pyrolyzer. At all times, you will practice great engineering intuition to ensure a safe and reliable solution is implemented.

Your Responsibilities:


  • Conduct feasibility studies, pilot testing, material and energy balances, and scale-up strategies for pyrolysis technology.
  • You’ll be testing and iterating on the next generation of Charm pyrolyzers to develop process systems for biomass conversion and production of bio-oil and biochar.
  • Collaborate with engineering, operations, and project management teams to implement new process improvements.
  • Ensure compliance with environmental regulations, safety standards, and industry best practices.
  • Troubleshoot and resolve process-related challenges in pyrolysis systems.
  • Provide technical leadership, mentorship, and training to junior engineers and cross-functional teams.
  • Like every member of our engineering team, you will occasionally be supporting our 24/7 operations via 2-3 weeks of after hours support throughout the year.

You Bring:


  • Bachelor’s degree in Chemical Engineering, Mechanical Engineering, or a related field.
  • Minimum of 7+ years of experience in process engineering, with at least 5 years focused on pyrolysis or thermal conversion technologies.
  • Strong understanding of heat transfer, mass balance, reaction kinetics, and thermochemical processes.
  • Strong hands-on experience with pilot plant operations, rapid prototyping, troubleshooting, and creative thinking to answer critical design questions.
  • Excellent problem-solving, analytical, and communication skills.
  • A self-directed mentality. You’re constantly balancing cost, timeline and impact when making decisions on what to do next. You can find out where you can add the most value to the team and the organization.
  • An excitement for scaling up hardware that has the potential to positively impact climate change!

Bonus if you bring:


  • Master’s or Doctoral degree in Chemical Engineering, Mechanical Engineering, or a related field.
  • Experience with biochar, syngas, or advanced chemical recycling technologies.
  • Familiarity with industrial-scale pyrolysis units and biomass valorization techniques.

Life at Charm Industrial

Charm Industrial is working to produce reliable, cost-competitive hydrogen from biomass. Humanity uses 65 million metric tons of hydrogen annually for ammonia production, hydrocracking, and other refinery processes. Nearly all of this hydrogen is produced from steam methane reformation, which is reasonably efficient but is responsible for ~1% of all global carbon dioxide emissions. This $130B market is expected to grow to $180B by 2023. Our approach to producing industrial hydrogen is unique, and allows us to deliver carbon-neutral hydrogen reliably and cost-effectively. To do this we've integrated a specially-chosen biomass crop, tightly coordinated farm operations, and a novel gasification system. Our engineering team is based in San Francisco.
