Hardware Engineer

## About the role 7th Unit is building a wheeled upper-body humanoid robot for industrial deployment in Central Asia and Eastern Europe. This is a founding role, you own the hardware architecture from day one. ## What you'll do - Define arm and actuator architecture for v1 — degrees of freedom, actuator selection, mechanical design - Design and build the gripper system optimized for our first deployment object set - Develop the hot-swap battery system enabling continuous multi-shift operation - Own structural design with field serviceability and manufacturing scale in mind - Integrate with wheeled base platform sourced from established robotics component suppliers - Define hardware-software interface and motor control integration within the ROS2 architecture ## What we need - 3+ years designing and building physical robotic systems that operated outside a lab - Hands-on experience with actuator selection, motor control integration, and real-world mechanical failure modes - You have personally assembled and debugged a working robotic system end-to-end - Comfortable making architecture decisions under uncertainty and iterating fast - Experience with off-the-shelf component integration is a strong plus ## Structure - Role begins mid-late summer 2026 - Equity negotiated directly, founding engineer package - Remote during pre-build phase. In-person required from prototype assembly onward
