About the role

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.

Job Overview
Do you have the ability to fundamentally redesign a variety of parts, components and subsystems to knock out lingering problems?
Do you have a knack for diagnosing difficult real-world issues escalating from product in the field?
Have you reviewed a design and been able to predict issues that will accelerate its end of life?
Have you had to invent a tool to service a component or system in the field or changed a process to make routine service much easier?
If you are obsessed with solving real functional design problems for complex equipment then you can make an impact here at Mainspring Energy. This Mechanical Engineer will focus on continuous improvements to our breakthrough Linear Generator hardware. In many cases, this will involve extensive root cause analysis, creative troubleshooting, broad engineering knowledge, fast problem solving, creating and running tests, evaluating field and test data, interfacing with design team, and general project management. Ultimately, you will be asked to validate a solution and help shepard that solution through an ECO process.

Responsibilities

  • Address critical mechanical field failures for the Linear Generator. Use field data to track and prioritize each issue over time, determining root cause, designing solutions, qualifying the changes, and pushing the changes into production / field retrofits though an ECO process.
  • Interface with the manufacturing and supply chain teams to address production issues. Use test and manufacturing data to track and prioritize each issue over time, determining root cause, designing solutions, qualifying the changes, and pushing the changes into production / field retrofits though an ECO process.
  • Create, optimize, and manage internal improvement systems that feed this learning back into the design process to reduce/eliminate future field or production failures. Intimate involvement with the design process to eliminate as many issues as possible.
  • 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 designs into production.

Qualifications

  • Degree in Mechanical Engineering or a similar engineering field from an accredited institution. Experience and degree will determine
