About the Job
Company Overview
Mainspring Energy is revolutionizing power generation with the world’s most flexible and adaptable onsite power generator, the Mainspring Linear Generator. Commercial, industrial, and utility leaders are choosing Mainspring over traditional options like engines, turbines, and fuel cells to quickly and reliably deliver local power for EV charging, commercial facilities, data centers, and grid-scale operations. The Mainspring Linear Generator is fuel flexible, ramps up and down to meet demand, and utilizes a flameless technology with near-zero NOx emissions.
Backed by top-tier investors such as Khosla Ventures, Bill Gates, American Electric Power, and Lightrock, Mainspring designs, manufactures and delivers its products to customers across the U.S. today, and we’re quickly scaling for international expansion.
Inspired by our vision of the affordable, reliable, net-zero carbon grid, Mainspring is rapidly expanding within the $816B global electricity equipment market, and we’re hiring the best talent to meet growing customer demand around the globe. We welcome a broad range of backgrounds, experiences, and talents to bring fresh perspectives and ongoing innovation to our customers.
We are looking to build relationships with people who share our values:
Pragmatic Optimism. Building a new category of world-class power generation requires the optimism of ambition and creativity, balanced with practicality to solve problems efficiently. The challenges that arise are opportunities for growth.
Excellence without Ego. We bring expertise and commitment to creating the best customer experience, from sales to deployment and service, just as we apply deep technical rigor to building and delivering world-class products. We strive for excellence and behave as leaders with the humility to acknowledge our challenges, both collectively and as individual contributors.

Job Overview
Mainspring is seeking Staff Mechanical Design Engineer with a focus on developing a high-voltage linear electromagnetic machine (LEM) for improved performance, cost, and reliability. You will design and advance new components and subsystems with challenging technical requirements from initial concept through successful manufacturing launch. You will manage existing concepts through development, deployment, and manufacturing. At staff level, you will lead projects with potential for direct reports. Mainspring is a great place for engineers who have a variety of areas of deep expertise and like to solve challenging cross-functional problems requiring a mix of computational analysis, hands-on engineering and team effort.
Responsibilities
- Lead and participate in brainstorming activities to develop novel ways to improve all aspects of the LEM and the Linear Generator broadly.
- Develop and optimize key mechanical and electromechanical subsystems within the LEM to drive down cost, improve performance, and deliver high reliability. These systems may include: magnetic encoders and other position sensors; high-voltage wiring and coil design; precision-machined steel and cast-iron components; magnet array assembly methods; composite material manufacturing and analysis; air bearing design, development, and testing.
- Work with reliability and test teams to validate systems and components with fast cycles of learning for deployment into the next generation of Linear Generators.
- Collaborate cross-functionally with manufacturing engineering, NPI, and external suppliers to rapidly deploy new designs into production.
- Provide technical guidance to junior engineers and technicians, and contribute to the continuous improvement of engineering processes, tools, standards, and best practices
Qualifications
- Degree in Mechanical Engineering or a similar engineering field from an accredited institution. Experience and degree will determine level, but minimum requirements are: Staff Level: BS + 10 years or MS + 9 years
- Deep understanding of metal castings, machining, welding/fabrication, bolted connections, datum selection, large tolerance stackup analysis, and finishing processes with the ability to identify and resolve design for manufacturability issues.
- Demonstrated experience with volume manufacturing of electric motors or generators, including: Design for Quality, inspection and testing methods, insulation system design and certification, formed and wound coil design, magnetic material specification and handling, lamination design and manufacturing.
- Extensive experience working directly with suppliers, vendors and contract manufacturers to address quality or manufacturing issues.
- Ability to work independently, manage multiple projects in a fast-paced environment, and demonstrate leadership and mentoring abilities
- Fluent in SolidWorks or comparable CAD package. Experience with using PDM or a similar CAD version control system is preferred.
- Interest in developing creative and cost effective solutions to enable the deployment of zero carbon energy technology at large scale.

<p class="text-steel f-b1 md-max:mb-d">At Mainspring we believe the fastest path to the net-zero carbon grid is vastly increasing the amount of solar and wind power while building a supporting clean energy system that ensures affordability and multi-day, cross-season resilience. Getting there requires flexible, scalable, local technologies that can adapt to the shifting grid landscape – including the transition from natural gas to renewable fuels like biogas, green ammonia, and green hydrogen.</p> <div> <p class="text-steel f-b1">The Mainspring Linear Generator delivers an unmatched level of flexibility for the transition ahead. It’s local so you can site where power is needed, it’s dispatchable so you can ramp up and down to complement renewables, and it’s fuel-flexible so you can operate on the cleanest fuels available today and in the future. Our products are already at work at Fortune 500 customer sites, accelerating the arrival of the net-zero carbon grid.</p> </div>
