Sr. Mechanical 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. 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 Senior 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! We have ambitious goals, help us make them possible! \n Your Responsibilities Design unique solutions for our next generation operations pyrolyzer: Develop mechanical and electromechanical systems for production use while considering interfacing systems, operating requirements, operator burden, and regular service and maintenance. Consider what technology needs thorough R&D to simplify and redefine our machine architecture. Learn from previous successes and failures to develop and integrate novel vessels and process steps that tie back to real business needs. Work with our testing team to validate performance before operations integration. Conduct thorough engineering analysis: Work with process engineers to develop thermal and flow models to inform system design. Process piping and vessels are important components in our greater pyrolysis system, refine their mechanisms to deliver an industrial solution. 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 for production hardware: 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 field Seasoned mechanical design experience (5-8 years) CAD knowledge is a must, we use OnShape Experience reviewing and releasing detailed fabrication and assembly drawings with a high attention to detail and strong configuration control practices Skilled in modes of heat transfer, sensor and actuator selection for robust operations, and building project requirements from ambiguity Skilled with basic fabrication techniques and the design principles around them Familiarity with piping standards, flange interfaces, gasket selection, and mechanical integration of process systems. Hands-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 Skilled with electromechanical systems and design for material handling, think conveyors, pumps, and blowers Experience designing mechanical weldment under load and process pressure 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. Ability to communicate priorities, system progress, and work cross functionally Hands-on mechanical troubleshooting and assembly experience An excitement for scaling up hardware that has the potential to positively impact climate change! Bonus, if you Bring A Masters degree in Mechanical Engineering, or a related field Onshape modeling experience Experience with process piping and vessel design in high-temperature or industrial environments Design of operations facing industrial equipment Experience with 24/7 operations \n $96,000 - $144,000 a year \n What We Offer Equity ownership through stock options 100% employee healthcare premiums covered Comprehensive medical, dental, and vision coverage with multiple plan options Employer-funded HSA contributions for eligible HDHP plans Traditional and Roth 401(k) with a 50% match on contributions up to 6% Paid leave, including parental and medical leave PPE and workwear allowances Annual professional development stipend Employee recognition programs that celebrate impactful work and team contributions Opportunities for internal growth, career development, and transition into climate from a range of industries and backgrounds Visa Sponsorship Policy Since we are a small startup, certain accommodations for visa sponsorship may not be within our capability. At this time, Charm Industrial is only sponsoring E3 and TN visas. 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.
