Lead Robotics Engineer

Proto-Town•Lockhart, TX

About The Position

We are building a legged quadruped robot that carries a human rider, starting from scratch. There is no platform to modify, no reference design to scale up, and no prior program here to inherit. You would be the technical owner of the machine as it comes into existence: architecture, actuation strategy, prototype hardware, and the locomotion control stack.

Requirements

Expertise in mechatronics, spanning mechanical design, motor control, and power electronics.
Experience with high-power electronics: Multi-kilowatt DC bus architecture, motor drive and inverter design or deep integration, battery pack and BMS selection, and thermal design.
Proficiency in motor control: Field-oriented control, torque control, encoder and current sensing, and real-time firmware on embedded targets.
Experience in actuation: High torque-density drivetrain design (motors, gearboxes, backdrivability).
Fluency in the practical stack: C++ and Python, a real-time control target, CAN or EtherCAT.
Experience with a trusted simulator and understanding its limitations.
