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. Join us in 2026 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. 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

This position is a critical member of the Materials Science and Engineering (MSE) team at Charm! You will lead development of the analytical lab where you and your team will deliver high impact measurements and data conclusions for Charm, including continuous development and refinement of measurement methods. These contributions tie you closely to key business outcomes in the form of: unlocking real-world carbon dioxide removals, discovering and characterizing new behaviors of Charm’s materials to enable product-market fit, and helping solve highly dynamic operations challenges experienced in the field.

This role is highly cross-functional, requiring close collaboration with fellow scientists, engineers, and other Charmers across the Engineering, Operations, Measurement/Reporting/Verification (MRV), and Development organizations. You will function as a subject matter expert on chemical principles + sampling methods and be responsible for planning, collecting, and evaluating samples captured throughout Charm’s business activities (biomass, pyrolysis, injection, etc). As required by various research campaigns, business/sales opportunities, or production anomalies, you will have the opportunity to influence the strategy around how Charm studies, quantifies, and ultimately solves problems using your subject matter expertise. This role will report to the Head of Engineering in Colorado.
