Robotics Maintenance & Field 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 improve. We offer an exceptional opportunity to participate in building next-generation commercial humanoid robots from 0 to 1, alongside competitive compensation and an international engineering environment. We are 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 platform and bring it to production.

We are looking for a Robotics Maintenance & Field Engineer to guarantee high hardware uptime, lead physical repair and preventative maintenance routines, conduct electro-mechanical field troubleshooting, and support live field operations for our humanoid robot fleet.

• Versatile mechatronics technician and engineer who can comfortably replace carbon-fiber structural limbs, repair dense harnesses, trace bus communication faults, and flash low-level firmware.
• Field-oriented problem solver who thrives under live demonstration pressure, maintains a calm technical demeanor, and prioritizes safety.
• Methodical practitioner who tracks hardware failure metrics, builds field maintenance guides, manages spare parts inventories, and feeds failures back to R&D teams.
• A strong collaborator across test operations, hardware design, embedded software, and customer support teams.

• Maintain, inspect, diagnose, and repair complex humanoid robot hardware, including joint actuators, structural shells, power distribution units, and wiring harnesses.
• Execute scheduled preventative maintenance routines: joint zero-position calibration verification, fastener torque checks, structural wear inspection, and thermal lubricant replacement.
• Perform real-time troubleshooting of mechanical, electrical bus (EtherCAT/CAN-FD), sensor streaming, and control software deployment issues during lab testing and live customer demos.
• Manage firmware provisioning, software version deployments, configuration updates, and log collection across internal testing robot fleets.
• Organize, track, and optimize spare parts inventory, specialized repair tooling, diagnostic equipment, and transport deployment cases.
• Create comprehensive field maintenance manuals, teardown/repair SOPs, troubleshooting decision trees, and technician training modules.
• Log, track, and categorize hardware issues using ticketing systems (Jira), conducting initial root-cause analysis and feeding engineering logs back to R&D teams.
• Provide on-site technical operational support during high-profile public trade shows, customer field trials, and media demonstrations.

• B.Sc. or Associate Degree in Mechatronics, Electrical Engineering, Mechanical Engineering, or equivalent practical experience.
• 7+ years of field engineering, mechatronics maintenance, or system integration experience in robotics, industrial automation, or complex electro-mechanical platforms.
• Excellent hands-on mechanical and electrical repair skills: precision disassembly, soldering, wire crimping, torque wrench operation, bearing replacement.
• Proficiency using digital multimeters, oscilloscopes, CAN/EtherCAT bus analyzers, and Linux terminal command line diagnostics.
• Familiarity with Linux command-line tools, shell scripting, ROS/ROS 2 diagnostic commands, and firmware flashing procedures.
• Calm composure under pressure, exceptional safety discipline, and readiness for flexible field support travel.
• Strong written and verbal communication skills for cross-functional problem escalation.

• Direct hands-on maintenance experience with full-scale humanoid robots, quadrupeds, or multi-axis industrial robot arms.
• Experience managing robot fleet health monitoring software, Jira issue tracking, and spare parts BOMs.
• Valid driver’s license and willingness to travel for domestic and international live field operations.
• Comfortable communicating technical topics in English with international teams.
