About the company:

Charm Industrial is working to return the atmosphere to 280 ppm CO₂. We design, build and operate a fleet of mobile fast pyrolyzers that convert ag and forest biomass residues into bio-oil for use in carbon removal and direct-reduced-iron steelmaking.

In 2020 our Chief Scientist and co-founder Shaun Meehan had two breakthroughs (bio-oil intermediate and bio-oil sequestration) that kickstarted the company. Within 10 months we completed our first carbon removal injection and in 2021 we completed more than 5,000 tons of CO₂e removal for customers like Stripe, Shopify and Microsoft.

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 a Mechanical Engineer based out of our Fort Lupton facility, you’ll be responsible for designing the next generation of pyrolysis technology, implementing and troubleshooting mechanical systems in production, and collaborating with the broader engineering team, including electrical, automation, and manufacturing engineers, as well as fabricators and technicians. This group collaborates to overcome design/build/test challenges and successfully execute commissioning and production handover campaigns.

This role involves designing new mechanical systems, selecting electromechanical actuators, sensors, pumps, etc. and continually improving on our pyrolysis and biomass processing equipment. You’ll turn wrenches to help bring your designs to life and develop test plans to ensure your systems meet overall design intent. Often, you will be tasked with updating the configuration of legacy systems in order to validate novel design pathways or new subsystems, informing the architecture of our next generation of pyrolysis equipment. In order to meet Charm’s overall production and throughput goals, the role will leverage mechanical and system expertise to provide troubleshooting support for production machines based on issues observed by our Operations partners.

This role will report to the Lead Pyrolysis Engineer based out of Fort Lupton, Colorado. 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!

Our Commitment

Charm Industrial is an equal opportunity employer. We hire based on skills, experience, and passion for our mission. Climate challenges require a wide range of perspectives and expertise, and we welcome applicants from all backgrounds. We’re excited to grow our team with people who bring unique strengths and help us improve as a company.

Responsibilities

Design unique solutions for our next generation operations pyrolyzer: Develop mechanical and electromechanical solutions for production use while considering interfacing systems, operating requirements, operator burden, and regular service and maintenance.

Design solutions for our next generation R&D pyrolyzer: Scale our existing tech to higher machine throughputs while addressing new problems and plant requirements to push our tonnage down the cost curve. Learn from previous successes and failures to develop a first of its kind test article.

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.

Develop and execute test plans and commissioning campaigns: Take direct ownership of your designs beyond pressing print on your drawings. Validate performance before and after machine installation.

Collaborate with cross-functional teams: Work closely with electrical engineers, software developers, and other mechanical engineers to implement mechanical systems into the larger pyrolysis package

Support on-call production support as needed, if our frontline Engineering Technician group needs help solving critical Operations problems

You Bring

Bachelor’s degree in Mechanical Engineering, or a related fieldSeasoned mechanical engineering experience (3-5 years)

CAD knowledge is a must, we use OnShape

Proficiency in modes of heat transfer, sensor and actuator selection for robust operations, and building project requirementsExperience with DFMA and FMEA Familiar with GD&T, familiar with basic fabrication techniques

Familiarity with electromechanical systemsHands-on mechanical troubleshooting and assembly experience

A strong willingness to get your hands dirty and intimately interact with all pyrolysis system components

Documentation skills that demonstrate your thought process and design process when making improvements

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 as quickly as possible.

Use quick implementation skills to make quick and long-term fixes to the pyrolysis system in service of system improvement.

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