Electrical Engineer (San Francisco, CA) (BH0095)

San Francisco, CA, United States

About Charm

Our mission is to reverse climate change and return the atmosphere to 280 ppm CO₂, profitably. We convert waste biomass into carbon-rich bio-oil and inject it into permanent, underground storage as carbon removal, or reform the bio-oil to produce syngas for fossil-free steel.

Our carbon removal pathway took off in 2020 with initial purchases from customers like Stripe, Shopify & Microsoft. In 2021 and 2022 we delivered thousands of tons of carbon removal via off-the-shelf pathways, and also deployed our first R&D prototype pyrolyzer of our own. In the next 18 months, we'll build and deploy the next pyrolyzer revision, demonstrate our fossil-free ironmaking pilot, substantially expand our operations in Colorado and put thousands of tonnes of CO₂e underground.

We're looking to expand our team of ambitious creative and hands-on engineers, fabricators, operators, and forward-thinking humans. We value psychological safety and collaboration. We take calculated risks and don't sweep mistakes under the rug; instead, we pin them to the wall and learn from them. We value that everyone’s unique backgrounds and perspectives shape their work. We encourage you to read our company values .

Come help us reverse climate change. Gigatons or bust!

About the Role

Our Pyrotronics team is looking for an Electrical Engineer to support our pyrolysis team. This role includes the design, fabrication, test, and implementation of electrical control cabinets for our pyrolyzer prototypes. You will interface with cross functional teams including fabrication, test, and engineering. Your first project will be to design a control box for the reactor potion of our new test stand. We are building a test fixture that is modular. It will have separate control boxes for each portion of the pyrolyzer: Biomass metering, reactor, condenser, separator, and gas combustion. The control boxes can be used as stand alone test stations with an HMI, or they will be combined to form larger test stands.

Responsibilities: Using the rest of the Pyrotronics team as a resource, you will design and develop automation control cabinets. This includes selecting motor controllers and VFDS, designing basic AC circuits and wiring harnesses, and selecting appropriate PLC cards and how they interact with all the sensors and actuators. You are then responsible for creating electrical schematics, selecting appropriate components and creating a bill of materials. Then you get to build it!

Collaborate with cross-functional teams: Work closely with mechanical engineers, software developers, and other stakeholders to integrate control systems, motor controllers, VFDs, and industrial sensors into larger automation projects.

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.

Documentation and reporting: Create detailed technical documentation, including sensor specifications, sensor integration plans, drawings, specifications, and test reports, to support system integration, maintenance, and future enhancements.

Implement basic PLC systems: Use the building blocks created by our sensors and controls team to build basic HMIs.

Requirements: Excitement about getting opportunities to build rapid prototypes, get your hands dirty by working side-by-side with a cross functional team.

4 years or more of Electrical, Electronics or Controls Engineering (or similar) professional experience.

Experience in designing automation control cabinets and constructing cable assemblies.

Experience with electrical schematic capture tools (We use Zuken).

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 pounds at a time.

Have a proactive, professional and “can do” attitude.

Passionate about contributing to our mission and growing the company.

Willingness to travel once or twice a year to Fort Lupton, CO to visit with our Colorado team.

Bonus (but not required): Bachelor's degree in Electrical Engineering, Mechatronics, or a related field

Familiarity with programming languages for PLC systems, such as ladder logic or structured text

Understanding of automation control systems, motor control principles, electrical circuit design, and industrial sensors

Proficiency in selecting motor controllers, VFDs, and industrial sensors based on project requirements

Knowledge of safety regulations and standards related to high-power systems

Experience designing for or operating near high power equipment (high voltage, large horsepower motors, high force actuators …etc)

$100,000 - $125,000 a year The anticipated salary range is dependent on factors such as experience within the job, within the industry, education, location, etc What We Offer

· Stock options

· Health benefits (medical, dental, vision)

· Traditional and Roth 401(k) with a 50% match on contributions up to 6%

· Paid time off, including parental leave

- A yearly professional development stipend

· Healthy snacks and lunches for onsite employees

- A sweet workplace with lots of space inside and out

· A chance to pivot into a role in climate!
