Process Development Engineer - Pyrolysis Test

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 We’re looking for a Process Development Engineer to join our Pyrolysis Test Engineering team. Reporting to the Director of Pyrolysis, you’ll help scale new chemical processes from laboratory and pilot-scale testing to commercial operation, ensuring they are efficient, safe, and cost-effective. Working closely with engineers, scientists, and operations teams, you’ll investigate scale-up challenges, evaluate process performance, improve product yields, and support the development of safe and reliable operating practices. You’ll play an important role in translating experimental results into processes that can be successfully deployed at commercial scale. The ideal candidate has experience with pilot plant operations and process scale-up, along with strong analytical, problem-solving, and communication skills. This role requires close collaboration across disciplines and the ability to clearly communicate technical findings to a range of stakeholders. This is an opportunity to contribute to the development of novel chemical products and processes that support Charm's carbon removal mission. This role is based onsite in Fort Lupton, Colorado.
