About the role
About Fourier Fourier is focused on making on-site hydrogen universally accessible . Our breakthrough architecture enables highly modular and fully automated electrolyzers that scale to any size and optimize efficiency at all loads. We are on a mission to transition the global energy landscape toward a purely sustainable and emission-free future by unlocking the full potential of hydrogen as a clean energy carrier. Role Overview Fourier Earth Inc. is seeking a Director of Power Electronics Engineering to lead the development of critical power electronics systems for our next-generation electrolyzer platforms. This role will combine deep technical expertise with strong leadership , guiding architecture decisions, driving hardware development, and building a high-performing engineering team. You will play a key role in developing high-efficiency power conversion systems that enable scalable hydrogen production and ensure our technology performs reliably across a wide range of operating conditions. You will lead the design, integration, and deployment of all electrical systems powering our H2 electrolyzers and all supporting equipment for a fully functional and automated hydrogen production system. The candidate will possess deep technical expertise in power conversion and industrial distribution, but have the broad systems-level vision to seamlessly integrate the hardware with mechanical constraints and software/firmware controls in a hazardous environment. The ideal candidate brings extensive experience in power electronics design, high-power systems, and system-level architecture in accordance with compliance standards, along with a proven ability to mentor engineers and lead complex hardware programs from concept through production .
Responsibilities Architectural Leadership: Own the end-to-end electrical architecture from the 480V grid tie-in down to the 12V/24V DC sensor networks, ensuring clean power distribution, signal integrity, and EMI/EMC compliance. Power Conversion & Load Management: Oversee the design and specification of AC/DC rectification for the electrolyzer stack, DC/DC converters, and the integration of VFDs and SCR controllers for heavy industrial loads. Systems Integration: Act as the technical bridge between Hardware, Controls, and Software teams. Define firmware
