Mechanical Engineer II (Pyrolysis)

Colorado, U.S.

Full-Time

$74,400 – $111,600 per year

TLDR

Design next-generation pyrolyzer systems and lead test plans, commissioning, and cross-functional integration for scalable production.

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! Your Responsibilities

Design unique solutions for our next generation operations pyrolyzer: Develop mechanical and electromechanical systems for production use while considering interfacing systems, operating requirements, operator burden, and regular service and maintenance. Consider what technology needs thorough R&D to simplify and redefine our machine architecture. Learn from previous successes and failures to develop and integrate novel vessels and process steps that tie back to real business needs. Work with our testing team to validate performance before operations integration.
Conduct thorough engineering analysis: Work with process engineers to develop thermal and flow models to inform system design. Process piping and vessels are important components in our greater pyrolysis system, refine their mechanisms to deliver an industrial solution.
Troubleshoot and resolve issues: Identify and troubleshoot mechanical system malfunctions and performance gaps. Determine why a failure mode is observed and implement a corrective action to return the system to optimal performance.
Develop and execute test plans and commissioning campaigns for production hardware: Take direct ownership of your designs beyond pressing print on your drawings. Validate performance before and after machine installation.
Collaborate with cross-functional teams: Work closely with electrical engineers, software developers, and other mechanical engineers to implement mechanical systems into the larger pyrolysis package
Support on-call production support as needed, if our frontline Engineering Technician group needs help solving critical Operations problems

You Bring
