Senior Pyrolysis Systems Commissioning Engineer

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.

Come help us reverse climate change. Gigatons or bust!

This role is a hands‑on execution role, collaborating with pyrolysis engineering, process development, and commissioning operations. You will be the technical backbone of Charm’s pyrolyzer iteration cycle – owning everything from contract manufacturing coordination and pre‑shipment testing through onsite commissioning, operator training, and continuous improvement. As we advance successive revisions of our pyrolysis systems, you’ll ensure each new unit arrives ready to run and keeps running reliably.

You will report to our Lead Manufacturing & Process Engineer and work from our Fort Lupton, CO production site alongside a cross‑functional team of engineers, technicians, and operations leadership.

• Build and maintain a strong working relationship with Charm’s future contract manufacturer as production ramps, serving as the primary technical liaison for manufacturing quality and build conformance.
• Communicate engineering change orders/design feedback, field‑observed issues, and process improvement requests back to the contract manufacturer in a clear and structured manner, while staying in lockstep with our internal Procurement Manager.
• Own end‑to‑end commissioning of new pyrolyzer revisions as they arrive from our internal build teams or contract manufacturing partners, including system integration into existing infrastructure (power, biomass feed, bio‑oil and char outputs). This will require collaboration and scoping across subject‑matter experts and design engineers to ensure proper system checkouts and acceptance criteria are planned.
• Conduct onsite testing and acceptance activities on the shop floor, verifying conformance to design specifications and operational readiness. This could manifest in our backyard for internally‑built systems, or at a partner contract manufacturer prior to shipment.
• Lead the physical stand‑up of new pyrolyzer units onsite, coordinating with technicians, engineers, and operations leadership to achieve safe, reliable first operation.
• Develop deep working knowledge of how the pyrolyzer functions, common failure modes, and how each subsystem integrates, becoming the go‑to technical resource for commissioning and troubleshooting.

• Establish baseline process flow models to capture the current state of the manufacturing system; use these to highlight and prioritize improvement opportunities.
• Work alongside operators to identify and formally document pain points, translating operator feedback into structured design and process improvement proposals.
• Design, test, and implement tooling improvements for pyrolyzer cleaning, turnaround, and maintenance activities.
• Contribute to new product design processes and design reviews, embedding design‑for‑operations strategies into pyrolyzer hardware development.

• Own and continuously maintain the pyrolyzer SOP, work instructions, and troubleshooting guide, ensuring they reflect current hardware and field‑learned best practices.
• Generate clear, visual‑aid‑rich engineering work instructions for reliable operator execution.
• Develop and refine data collection methods for MRV (Monitoring, Reporting & Verification) and financial tracking of manufactured products, integrating these into ERP and MES systems.
