About the role

Responsibilities

  • Lead end-to-end design of complex, multi-layer PCBs, including schematic capture and layout.
  • Integrate microphone arrays with acoustic team, ensuring signal integrity for low-noise, multichannel audio acquisition.
  • Design and optimize power distribution and control systems for high-torque motors and edge-compute hardware like NVIDIA Jetsons.
  • Create robust electrical designs for extreme temperature, humidity, and mechanical vibration.
  • Develop circuits for motor controllers, sensor interfaces, and communication protocols (e.g., CAN bus, EtherCAT).
  • Debug hardware using oscilloscopes, logic analyzers, and rework stations.

Requirements

  • Proven track record of shipping real-world physical systems.
  • Mastery of Altium, KiCad, or similar for high-density PCB design and power electronics.
  • Understanding of EMC and electrical safety requirements.
  • Hands-on experience with digital audio interfaces (I2S, TDM, PDM) and high-speed communication protocols.
  • Bias toward action; comfortable in lab or field.
  • U.S. Citizenship and ability to pass background check.

Nice-to-Haves

  • Prior experience with DoD codes and standards for electrical systems.
  • Experience with power systems for high-speed gimbal or turret systems.
  • Security clearance or ability to obtain one.
