Heron Power
Develops solid-state transformers for grid modernization
Heron Power is a startup company building cutting-edge power electronics for the 21st-century grid. We aim to debottleneck the growth of electricity generation and consumption with scalable, innovative, and less costly hardware solutions, accelerating the electrification of everything.
Our first focus goal is to build better converters (inverters & rectifiers) to connect large-scale renewables, storage, and loads to the grid. Heron Power’s leadership team is made up of seasoned veterans who have designed and shipped gigawatts of power conversion products over the past decade.
We understand that no one individual knows everything. We will all learn a lot together and from each other. We strive to build a collaborative, enriching environment conducive to personal, technical, and career growth. You can expect to work in a dynamic and collaborative environment, driven by first principles engineering, solving difficult problems.
As an Intern, Firmware Engineering, you will be responsible for developing and testing embedded firmware for our power conversion products. Additionally, you will help with hardware bring-up, test automation and development tooling, working alongside experienced firmware and hardware engineers.
Write and debug embedded C firmware for microcontrollers
Implement test cases and automate test execution, including unit tests, hardware-in-the-loop tests and real hardware bench tests
Hardware bring-up and firmware debugging using lab/debugging tools
Improve build, test and development tooling
Write clear documentation and take part in code reviews
We have a short list of must-have requirements. We prioritize a strong grip on first principles, hands-on skills, and a sense of initiative. Domain-specific knowledge and experience will help determine the career level for each hire.

If you are passionate about technology and enjoy working in a fast-paced environment, we would love to hear from you. Join us in accelerating the electrification of everything at Heron Power.
Develops solid-state transformers for grid modernization
Heron Power designs power-electronics-based solutions to modernize the electrical grid, emphasizing solid-state transformer technology. Its flagship Heron Link is a modular, megawatt-scale converter that connects directly to medium voltage and uses wide-bandgap semiconductors to regulate voltage and frequency while coordinating multiple energy sources through software. Compared with traditional transformers and early SS-T solutions, it offers higher power density, easier maintenance, and tighter grid stability through software-enabled control. Its goal is to enable a scalable, reliable, all-electric grid for renewables, storage, and data centers, with internal pilots in 2026 and U.S. manufacturing planned.
