Vice President, Electrical Engineering

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

The Linear Generator is unlike any other generator technology on the market - it is a system that couples a chemical reaction and thermally-driven expansion directly to a linear motor for energy generation and control - called the Adaptive Pressure Cycle. This puts the controls and power electronics at the center of the design, and we’re looking for a leader who can thrive in a dynamic environment with many systems-level tradeoffs to balance. It is important that they have a deep understanding in many of the critical areas: power electronics / motors / inverters, PCBA designs / mixed-signal routing, low-noise analog signal conditioning and high-EMI environments. They must also have significant practical experience bringing power electronics to market, with a good understanding of high volume manufacturing and attaining high quality and reliability at low cost. This person must be an excellent leader who personifies our core values and can grow the team to accomplish our goals. This position reports to the SVP of Engineering, and is expected to be onsite at least 60% of the time.

Lead all electrical hardware development for complex power electronics and controls boards, both inside the Linear Generator and also all of the grid integration equipment Manage the development systems and processes, product deliverables and roadmap, strategy and goals Manage a high-performing electrical team and work in close coordination with the controls and software teams Partner with Manufacturing, Supply Chain, and Quality to optimize products for DFM and cost Drive the compliance strategy to secure all critical regulatory certifications

Degree electrical engineering with 16+ years of experience, including 10+ years managing multi-disciplinary engineering teams Proven track record of commercializing heavy industrial power hardware, e.g. utility-scale generators, inverters, or microgrid systems, from initial topology and rapid prototyping through DFM, DFT, and high-volume utility-grade scaling Proven success growing and managing technical teams Experience designing complex systems that require complex engineering, risk, cost, and requirements tradeoffs to co-optimize across a wide variety of disciplines, e.g. firmware/software, thermal, mechanical, electrical, supply chain, reliability, systems, etc. Thrives in a fast-paced startup environment - building the company while building the product
