Mainspring Energy designs and manufactures fuel-flexible linear generators—dispatchable, low-emission units scalable from ~250 kW to grid-level arrays—deployed onsite for data centers, EV microgrids, commercial, industrial, and utility customers.
About Mainspring Mainspring Energy manufactures and delivers fuel-flexible, low-emissions local power solutions that rapidly add new capacity and deliver reliable, affordable, and sustainable electric power. The company began commercial shipments of its Mainspring Linear Generators in 2020 and today has hundreds of megawatts in advanced development and field operations for leading Fortune 500 companies, data centers, and utilities. Mainspring also partners with global energy leaders including AEP, NextEra Energy Resources, Schneider Electric, and more. The core values that ground our work, guide our decisions, and connect us together: Pragmatic Optimism Excellence without Ego Proactive Collaboration Job Overview Mainspring Energy is accelerating the transition to a clean energy future through the manufacturing and deployment of our innovative Linear Generator technology. The Mainspring Linear Generator delivers highly efficient, dispatchable, and clean power with the unique ability to switch seamlessly between multiple fuels (including natural gas, biogas, and green hydrogen). As we scale our deployments from Behind-The-Meter (BTM) commercial microgrids to utility-scale Front-of-the-Meter (FTM) data centers and power plants, we are expanding our system boundaries to provide fully integrated, turn-key power solutions This role sits at the intersection of power systems engineering, cross-functional hardware integration, and external vendor management. You will act as the technical anchor, translating high-level single-line diagrams and architectural concepts into robust, mass-manufacturable modular products. The ideal candidate will bridge the gap between initial concept and factory-ready design by driving requirements across internal multidisciplinary teams (Electrical, Mechanical, Project Delivery, Software Controls, and Supply Chain) while managing critical 3rd-party design and manufacturing partners to scale the product line.
