Fullstack Hardware Engineer (US)

We are looking for a Fullstack Hardware Engineer with 1-5 years of experience to join a small, elite team building the first consumer platform robot designed for mass markets. You'll work across the entire hardware stack, mechanical, electrical, firmware, and production, to help bring a groundbreaking humanoid robot from prototype to product. This is a rare opportunity to own major subsystems end-to-end at a YC-backed robotics company working closely with the top physical AI labs. We want passionate builders who have made things from scratch, take deep pride in their craft, and thrive in a high-intensity, high-ownership environment. If you've ever built your own electric bike, car, 3D printer, or shipped a real product, we want to talk to you.

What will you be doing?

• Design and architect complete robot systems, mechanical CADs, PCB layouts, cable harnesses, and battery management systems, owning projects from concept through assembly

• Write firmware for microcontrollers and FPGAs, programming in Python, C, C++, and Arduino to bring up and debug new boards

• Build fast, hacky prototypes and iterate them into polished, production-ready consumer hardware

• Collaborate cross-functionally with the AI team to ensure hardware and software decisions reinforce each other for the best integrated robot platform

• Participate in peer design reviews, manage supplier relationships, and help engineer production processes to scale manufacturing
