MESH is a power plant in a box, and power electronics is its heart. Your job is to design the inverter we build ourselves, and to own the conversion stage end to end. If you have taken switching converters from a blank schematic to hardware humming under real load, this is the machine you get to own.

First Order Effects (FOE) is building America's Infrastructure Prime for the robotic era. Autonomous ships, drones, and robots are rewriting how the world moves, fights, and builds - but none of them work without infrastructure to power them, connect them, and launch and recover them. That's what we build.

Our team comes from SpaceX, Anduril, Saronic, Lockheed Skunk Works, Forterra, and Fuse Energy. Before founding FOE, we built satellite ground stations that closed a national comms gap in days, deployed multi-megawatt power systems at commercial speed, and shipped autonomous surface vessels into Navy fleet production. We've built infrastructure at lightspeed before - now we're applying that playbook to an entire company.

Architect and design the in-house inverter and DC/DC stages for MESH: topology, device selection across MOSFET, GaN, and SiC, gate drive, magnetics, and thermal.

Take converters from schematic and simulation through prototype, bring-up, and test under real load.
