Hardware Engineer - Power Distribution Unit (Robotics)

Location: On-site in Shanghai, China

Company

Developing next-generation commercial humanoid robots using an AI-first approach that combines perception, reasoning, dexterous manipulation, and continuous learning.

What you will do

• Own the full life-cycle design of the humanoid robot Power Distribution Unit, including DC-DC conversion, dynamic load switching, power sequencing, and fault protection.
• Design surge protection, over-current, over-voltage, reverse-polarity, and inrush-current limiting circuits for high-torque BLDC joint actuation.
• Execute multi-layer, high-current PCB layouts with heavy copper, thermal vias, optimized loop inductance, and strict mechanical footprint constraints.
• Integrate voltage, current, and temperature monitoring through EtherCAT, CAN, or PMBus interfaces for telemetry delivered to the main compute system.
• Perform thermal modeling, derating analysis, loss calculations, board bring-up, signal and power integrity optimization, and environmental stress testing.
• Collaborate with harness and mechanical teams and lead power safety qualification and EMC/EMI compliance testing.

Requirements

• B.Sc. or M.Sc. in Electrical Engineering, Power Electronics, Mechatronics, or a related technical discipline.
• 5+ years of experience in high-density DC-DC converter design, power electronics, or PDU development for robotics, electric vehicles, or aerospace systems.
• Proficiency with Altium Designer, Cadence Allegro, or KiCAD for schematic capture and multi-layer high-current PCB design.
• In-depth knowledge of MOSFET, GaN, and SiC power switches, gate drivers, current-sensing topologies, and power supervisory ICs, with embedded-system capabilities to complete full-board hardware and software design independently.
• Hands-on experience debugging hardware with oscilloscopes, electronic loads, power analyzers, and thermal cameras.
• Knowledge of power-system safety clearances, creepage and clearance rules, and thermal dissipation strategies.
• Strong problem-solving skills and experience with root-cause failure analysis, including 8D and FMEA, on power hardware.
• Ability to work effectively in a fast-paced environment and iterate hardware designs rapidly.

Nice to have

• Direct experience designing PDUs or power electronics for humanoid robots, quadrupeds, or electric vehicles.
• Familiarity with ISO 26262 or IEC 61508 functional safety requirements for power distribution systems.
• Experience with embedded firmware for power management ICs and EtherCAT, CAN-FD, PMBus, or SMBus protocols.
• Comfort communicating technical topics in English with international teams.

Culture & Benefits

• On-site work at a new robotics Engineering Center in China.
• Collaboration with international engineering teams and headquarters.
• Opportunity to develop a full-size humanoid robot platform from initial design through production.
• Competitive compensation and an international engineering environment.
