Electrical Engineering Technician

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 Kansas. Join us in 2025 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

• As an Electrical Engineering Technician based out of our Fort Lupton facility, you’ll be responsible for implementing designs, troubleshooting, and debugging controls and electrical systems put in place to operate our pyrolysis and biomass processing equipment.
• This role involves implementing and wiring control cabinets (480V and below), selecting motor controllers, VFDs, industrial sensors, powering PLC systems, constructing cables, and designing simple AC circuits for powering our biomass processing and pyrolysis equipment.  You will also be tasked with implementing new sensors or systems that we find necessary to improve the functionality of our existing equipment, or troubleshoot when our equipment is not performing properly.  You will work closely with cross-functional teams to ensure proper functionality. This role will report to the Director of Operations Engineering based out of Fort Lupton. There will be regular meetings across the operations and new design teams operating in Colorado as you help build new cabinet designs and wiring harnesses for new R&D equipment, and flex to support active production machines.
• Someone successful in this role will enjoy bringing new designs to life through collaboration with design engineers and helping to test and commission this new equipment. This person also loves to solve puzzles of why equipment is not working properly, and will not want to stop until the puzzle is resolved.  This person will take pride in ensuring that the systems are online and operational for our operations team, and assist immediately in problem solving when the machines go down.  A great attitude in the face of difficult and fast-paced environments is a must!

Responsibilities:

• Troubleshoot and resolve issues: Identify and troubleshoot control system malfunctions, sensor inaccuracies, and communication problems, implement corrective measures, and perform system testing to ensure optimal performance.
• Select motor controllers, VFDs, and industrial sensors: Evaluate motor control requirements and process variables, specify suitable motor controllers, VFDs, and industrial sensors (e.g., pressure transducers, thermocouples, gas flowmeters, level sensors, scales, and strain gauges), and integrate them into the overall system design.
• Design and construct cables: Design cable assemblies, specify cable types, connectors, and wiring schemes, and build cables for the automation control systems, considering sensor connections and communication requirements.
• Design basic AC circuits: Develop electrical circuit designs for high-power systems, ensuring compliance with safety regulations and industry standards, while considering sensor integration and power requirements.
• Collaborate with cross-functional teams: Work closely with mechanical engineers, software developers, and other electrical engineers to implement control systems, motor controllers, VFDs, and industrial sensors into larger projects.

Requirements:

• 5+ years as a professional electrician or electrical engineering technician in residential and/or commercial construction, aerospace, automotive, oil & gas, or other relevant industry 
• Excitement about getting opportunities to build rapid prototypes, get your hands dirty and teaching others by working side-by-side with a cross functional team
• Experience in implementing electrical schematics and constructing control cabinet and cable assemblies.
• Strong problem-solving skills and the ability to troubleshoot control system and sensor-related issues
• Must be physically able to climb ladders, bend, or crawl in awkward spaces
• Must be able to lift up to 50
