On-site

At Mentee Robotics, we are redefining humanoid automation with an AI-first approach - combining perception, reasoning, and dexterous manipulation into fully autonomous systems that continuously learn and adapt.

We are now expanding with a new robotics Engineering center in China, working hand-in-hand with our engineering teams in headquarters. Its mission: to rapidly develop our next-generation full-size humanoid and bring it to life - a walking, working platform that becomes the foundation of our next generation of products. This is a small, senior, hands-on team where speed of iteration is the core value.

We are looking for an Electrical Engineer to own the robot's power: a simple, safe battery system, power distribution to dozens of high-current joints, and the wiring harness that ties the machine together. No hot-swap, no product polish - power management only where it is necessary, done right.

Who you are?

  • A pragmatic system electrical engineer - you scope to what the prototype needs
  • Safety-first where it matters: batteries, e-stop, and protection are non-negotiable
  • Comfortable owning everything from pack design to the last connector

Responsibilities:

  • Design a simple, robust battery pack for the prototype: cell selection, pack architecture, and the necessary battery management (protection, monitoring, charging)
  • Design robot-wide power distribution: bus architecture, regeneration handling, fusing, and pre-charge
  • Own the safety chain: e-stop, contactors, and fault disconnection paths
  • Design and route the full wiring harness - power and communication - through joints and limbs, together with the actuation team
  • Define connectors and cabling for high-flex, high-current robot use
  • Integrate compute and sensor power domains (Jetson, cameras, IMU)
  • Validate the power system under real locomotion loads; instrument and measure

Requirements:

  • B.Sc. or M.Sc. in Electrical Engineering
  • 5+ years in system-level electrical design for robotics, automotive, drones, or battery-powered machines
  • Hands-on experience with Li-ion battery pack design and BMS integration
  • Experience with high-current DC power distribution and protection design
  • Practical harness design experience: routing, strain relief, connectors for moving mechanisms
  • Strong lab skills and a safety-driven working culture

Advantages:

  • Experience in EV / automotive power systems (e.g., BYD, NIO, Xpeng, Xiaomi) or legged robotics
  • EMI/EMC mitigation experience in dense electromechanical systems
  • Familiarity with regenerative braking energy handling in motor-driven systems
  • Comfortable communicating technical topics in English with international teams
We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
