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 pathway took off in 2020 with initial purchases from customers like Stripe, Shopify & Microsoft. Since then we’ve scaled to thousands of tons of carbon removal, over a hundred employees, and now have three locations in San Francisco, Colorado, and Kansas. Come join us in 2024 as we aim to become one of the first companies to put 10,000 tons of carbon back underground!

We're looking to expand our team of ambitious creative and hands-on forward-thinking humans. We value psychological safety and collaboration. We take calculated risks and don't sweep mistakes under the rug; instead, we pin them to the wall and learn from them. We value that everyone’s unique backgrounds and perspectives shape their work. We encourage you to read our company values.

Come help us reverse climate change. Gigatons or bust!

About the Role

We’re looking for a mechanical engineer who can support our efforts towards designing an optimally performing pyrolyzer, the backbone to Charm Industrial’s operations.

The pyrolysis system consists of several subsystems, which you will master through your time at Charm. Some of the subsystems include a gas condensing system, a char extraction and cooling system, and a heat recovery system. Each of these subsystems have extreme complexity in their design due to the challenging conditions of the system.

This role will work closely with other design engineers, electrical engineers, and automation engineers to turn their designs into the most user-friendly systems possible for our budding operations team.

Designing these systems requires that the engineer can effectively research and source many different types of processing equipment and instrumentation, design and build prototypes, and design and execute testing procedures to effectively evaluate and optimize pyrolysis equipment. The dynamic nature of this role lends itself to someone comfortable working with their hands more than sitting behind a desk.

This engineer needs to know how to design complex systems that include a mix of custom designed components with off-the-shelf equipment.

This role would also serve as a resource to other mechanical engineers on the team. It wouldn’t be uncommon for another engineer to ask for a design review, or brainstorm actively with anyone on our engineering team; this would be no exception!
