Building the Gyms Where Physical AI Learns to Work
Physical AI can't be trained on the internet. It has to be trained in the real world - through seeing, hearing and feeling real tasks in real environments. That's what NEURA Gym is about: a global network of physical training centers where robots learn industrial skills directly from the people who've mastered them.
As (Senior) Robotics Commissioning & Service Engineer, you own the commissioning and maintenance of our humanoid robot 4NE1, from mechanical integration and calibration to a fully operational robot on our ROS2/Linux platform. You work within NeuraGym's shared infrastructure alongside MAiRA and MiPA, setting the standards, judgment calls, and escalation point for junior technicians.
Your mission & challenges
Commissioning
Integrate and calibrate drives, gear/actuator systems, sensors (encoders, IMUs, force/torque sensors, cameras), and fieldbus communication
Execute bring-up sequences (joint homing, calibration checks) and confirm firmware, sensors, and actuators are healthy before a session
Service & maintenance
Perform fault analysis across hardware/software; reproduce issues, interpret logs, and isolate root causes
Exercise sound judgment on fault states - know when to escalate versus reset and continue
Operate 4NE1 during data-collection sessions, ensuring reliable runs for our AI teams
Technical ownership & leadership
Set commissioning standards, document processes, and feed structured input into mechanical/software design
Guide and mentor junior technicians; act as escalation point for complex or undocumented issues
Work confidently with incomplete documentation in an active prototype environment - you help define the process
What we can look forward to
Experience
Several years hands-on experience in commissioning, maintenance, or prototype-building of complex mechatronic/robotic systems
Vocational training, technician qualification, or degree in mechatronics/electrical/mechanical engineering - or equivalent experience
Robotics & mechatronics
Hands-on experience with actuators, gear systems, and mechatronic assemblies; strong understanding of mechanical assemblies and drive technology
Troubleshooting mechanical faults (backlash, misalignment, wear) using standard tools (dial indicators, torque wrenches, alignment lasers, oscilloscopes)
Working knowledge of sensors (encoders, IMUs, force/torque sensors, cameras), fieldbus communication, and robot kinematics/control fundamentals
Software & systems (applied, not developer-level)
You don't need to write production software - just navigate Linux, read logs, and run small scripts.
Linux/Ubuntu command-line, SSH and remote access to robot compute
Start, stop, and monitor the ROS2-based stack; recognize when something isn't working to escalate or restart
Read and adapt existing Python scripts for diagnostics (no software development expected); basic Docker and TCP/IP networking
Commissioning & operations
Independent bring-up sequences and first-line triage; sound judgment on escalation vs. reset
Nice-to-have
Experience with EtherCAT · Basic C++ (read/adjust simple code) · Basic Git for firmware/config versioning
Soft skills
Genuine willingness to work hands-on with hardware in a fast-paced prototype environment
Structured, well-documented work style; comfortable with autonomy and ambiguity
Clear communication across mechanical and software teams; fluent in English, German skills are beneficial
