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.

Who you are:

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.

Responsibilities:

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.

Requirements:

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.

Advantages:

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.
