About the Job

Requirements

  • A degree in electrical engineering and 16+ years of experience, including 10+ years managing multidisciplinary engineering teams.
  • A proven track record of commercializing heavy industrial power hardware, such as utility-scale generators, inverters, or microgrid systems, from initial topology and rapid prototyping through design for manufacturing, design for test, and high-volume utility-grade scaling.
  • Proven success growing and managing technical teams.
  • Experience designing complex systems that require engineering, risk, cost, and requirements tradeoffs across disciplines such as firmware/software, thermal, mechanical, electrical, supply chain, reliability, and systems.
  • Ability to thrive in a fast-paced startup environment while building the company and the product.
  • Deep understanding of power electronics, motors, inverters, PCBA designs, mixed-signal routing, low-noise analog signal conditioning, and high-EMI environments.
  • Practical experience bringing power electronics to market, with an understanding of high-volume manufacturing and achieving high quality, reliability, and low cost.

Responsibilities

  • Lead all electrical hardware development for complex power electronics and controls boards, both within the Linear Generator and for grid integration equipment.
  • Manage development systems and processes, product deliverables and roadmap, strategy, and goals.
  • Manage a high-performing electrical team and coordinate closely with the controls and software teams.
  • Partner with Manufacturing, Supply Chain, and Quality to optimize products for design for manufacturability and cost.
  • Drive the compliance strategy to secure all critical regulatory certifications.

About the Company

Mainspring Energy

Onsite linear generators for scalable power

Mainspring Energy designs and ships onsite linear generators that produce electricity for commercial and industrial customers, data centers, utilities, and microgrids. The kit uses a straight-line motion that is converted into electric current by magnets moving through copper coils, driven by a flameless, low-temperature air-and-fuel reaction with only two moving parts and an oil-free air-bearing. The system is fuel-flexible, handling natural gas, biogas, hydrogen, ammonia, and propane, and it scales from about 250 kW to more than 100 MW, with near-zero NOx and no after-treatment required. The company sells power as a service, enabling installations with no upfront cost and ongoing payments based on energy use, aiming to lower operating costs and increase energy resilience for its customers.
