Testing & Validation Engineer

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 a Testing & Validation Engineer to own quality across the humanoid program: from joint-level dyno and life testing to full-system benchmarking and shipment readiness before delivery to headquarters. You define what 'done' means - for every component and for the robot.

Who you are?

• A test engineer with strong mechatronics intuition - you understand what you are measuring

• Structured and data-driven, but pragmatic about what a prototype actually needs

• Comfortable being the gatekeeper

Responsibilities:

• Build and operate the joint test infrastructure: dyno setups for torque, speed, efficiency, thermal, and life testing of actuator modules

• Define and execute component-level verification for boards, batteries, harnesses, and sensors with the responsible engineers

• Own integration verification at every stage: leg on bench, robot on gantry, free-standing, walking

• Define and run full-system performance benchmarking (payload, speed, endurance, repeatability) and reliability assessment

• Build the acceptance criteria and shipment-readiness process for every robot and subsystem delivered to headquarters

• Develop test automation (Python) and maintain traceable test records tied to hardware and firmware revisions

• Feed structured failure analysis back into design - you close the iteration loop

Requirements:

• B.Sc. in Mechanical, Electrical, or Mechatronics Engineering

• 5+ years in testing and validation of electromechanical systems: robotics, automotive, or automation

• Hands-on experience building test rigs and instrumentation (torque sensors, current probes, thermal measurement, data acquisition)

• Strong data analysis skills; Python proficiency for test automation and reporting

• Experience in defining verification plans, acceptance criteria, and reliability/life test programs

• Fluent English for cross-site collaboration with headquarters

Advantages:

• Experience at humanoid/robot companies, cobot firms, or automotive

• Actuator/servo dyno testing experience

• Familiarity with HIL testing and firmware validation

• Exposure to safety and compliance standards for robotics
