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!

About the Role

  • As Charm matures our Injection Operations, we need an engineer that can help solve urgent production bottlenecks.

  • The engineering challenges cover a wide variety of disciplines, including chemical engineering, mechanical engineering, automation and controls, as well as a firm understanding of process safety.

  • You will be joining a growing engineering staff that partners with the injection operations team who is ultimately responsible for injecting our bio oil underground! This role involves a unique combination of designing, testing, implementing, troubleshooting, and continuously improving process equipment, often with tight timelines.

  • You will work alongside fellow Charm engineering resources and injection operations team members to solve the company’s most pressing problems, and spend time in the field with our operators understanding the process and implementing creative solutions to make their work easier.

  • Someone successful in this role will enjoy bringing new designs to life and helping to test and commission their new equipment. This person takes pride in delivering robust mechanical solutions that work in the real world, and loves stepping through the root cause analysis process when systems are not performing as intended. This person also takes an analytical approach to problem solving and is not afraid to step out of their comfort zone when tackling new problems. A great attitude in the face of difficult and fast-paced environments is a must!


This role reports to the Lead Injection Engineer out of the Charm Colorado office.

Responsibilities

    • Design and work alongside a team to build and commission bio-oil pumping, storage, processing, and injection skids to ensure safe and efficient movement of bio-oil between tanker trucks and the wellbore.

    • Design resilient and redundant systems that will allow our injection systems to process tens of thousands of tonnes of bio oil injection throughput during 24/7 operations.

    • Leverage existing design review and releases processes to produce robust mechanical/system drawing packages, process control narratives (PCNs), and piping and instrumentation diagrams (P&IDs)

    • Perform FMEAs on all new hardware in collaboration with process safety professionals. Use the results to design and implement mitigations for scaled systems including engineered safeguards and administrative safeguards.

    • Ensure bio-oil preprocessing achieves regulatory, measurement, reporting, verification and operational requirements. Collaborate on new process development as needed.

    • 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.

    • Support on-call production support if our frontline team needs help solving critical Operations problems

    • Collaborate with cross-functional teams: Work closely with electrical engineers, software developers, and other mechanical engineers to implement your sub-assemblies into the larger injection system

You Bring

    • Bachelor’s degree in Mechanical Engineering, or a related field

    • Seasoned mechanical engineering experience (3-5 years)

    • CAD knowledge is a must, we use OnShape

    • Experience with DFMA and FMEA

    • Familiar with GD&T, familiar with basic fabrication techniques

    • Familiarity with electromechanical systems

    • Ability and excitement to get hands-on with hardware while you work alongside our diverse injection operations team

    • Documentation skills that demonstrate your thought process and design process when making improvements (e.g. work instructions, SOPs, and experience training operators on system operation.)

    • Ability to communicate priorities, system progress, and work cross functionally

    • A desire to work alongside Electrical & Controls Engineers and fabricators to turn solutions into physical, installed hardware with fast turnaround times. Use thorough implementation skills to make impactful and long-term fixes to the injection system in service of system improvement.

    • An excitement for scaling up hardware that has the potential to positively impact climate change!

    • A willingness to travel between 25-50% of the time to our injection sites and be on-call to support the operators in the field.

    • Bring a safety mentality to every task and have the courage to use Stop Work Authority

Bonus if You Bring

    Bonus, if You Bring:

    • Experience with thermal, chemical, electrical and/or mechanical processes and hardware such as work experience in oil & gas, aerospace, automotive or chemicals manufacturing.

    • A practical knowledge of industrial pump selection, fluid system design, or batch/continuous processing in production settings.
