Mechanical Engineer II (Pyrolysis)

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 Louisiana.

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. If you're excited about tackling big challenges, we encourage you to explore our company values .

Come help us reverse climate change. Gigatons or bust!

About the Role

As a Mechanical Engineer based out of our Fort Lupton facility, you’ll be responsible for designing the next generation of pyrolysis technology, implementing and troubleshooting mechanical systems in production, and collaborating with the broader engineering team, including electrical, automation, and manufacturing engineers, as well as fabricators and technicians. This group collaborates to overcome design/build/test challenges and successfully execute commissioning and production handover campaigns.

This role involves designing new mechanical systems, selecting electromechanical actuators, sensors, pumps, etc. and continually improving on our pyrolysis and biomass processing equipment. You’ll turn wrenches to help bring your designs to life and work with our Test & Process team to develop test plans to ensure your systems meet overall design intent. Often, you will be tasked with updating the configuration of legacy systems in order to validate novel design pathways or fully design new subsystems, informing the architecture of our next generation of pyrolysis equipment. In order to meet Charm’s overall production and throughput goals, the role will leverage mechanical and system expertise to provide troubleshooting support for production machines based on issues observed by our Operations partners. This role will report to the Lead Pyrolysis Engineer based out of Fort Lupton, Colorado.

Someone successful in this role will enjoy bringing new designs to life and helping to test and commission their new equipment. This person takes pride in delivering robust mechanical solutions that work in the real world, and loves stepping through the root cause analysis process when systems are not performing as intended. This person also takes an analytical approach to problem solving and is not afraid to step out of their comfort zone when tackling new problems. A great attitude in the face of difficult and fast-paced environments is a must. We have ambitious goals, help us make them possible!
