The Role

We are looking for a Field Service & Integration Engineer (m/f/d) to ensure our robotic platforms remain fully operational in real-world deployments.

You will perform maintenance and repairs, integrate new hardware modules, support battery and power system upgrades, and work closely with our engineering teams to ensure maximum reliability and uptime in the field.

Key Responsibilities

• Perform installation, commissioning, maintenance, and repair of our modular UGV robotic platforms at customer sites, test ranges, and field deployments
• Diagnose and resolve mechanical, electrical, and electronic issues — especially under harsh operational conditions
• Integrate new hardware modules, payloads, sensors, communication systems, and battery components into existing robotic platforms
• Handle and maintain high-voltage battery systems, including safety procedures, swapping, troubleshooting, and working with BMS and charging systems
• Set up and validate system interfaces (e.g., CAN, EtherCAT, Ethernet, serial communication)
• Collaborate with R&D and engineering teams to report field findings, propose improvements, and implement updates
• Create service and maintenance documentation, test protocols, and field reports
• Conduct technical training for customers, partners, and field teams on system operation and maintenance

Your Profile

• Degree in Electrical Engineering, Mechatronics, Robotics, or related technical field — or a strong technical apprenticeship with relevant hands-on experience
• Professional experience in field service, robotics, vehicle systems, machinery, or technical support roles
• Solid understanding of high-voltage battery systems (Li-ion, LiFePO₄), battery management systems (BMS), and relevant safety regulations
• Strong skills in electrical/electronic troubleshooting, wiring, connectors, and communication protocols
• Hands-on mechanical ability and experience working with tools, assemblies, and repairs in demanding environments
• Willingness to travel within Germany and occasionally across the EU
• Fluent in English; German skills are a plus
• Proactive, solution-oriented mindset and ability to work independently in field operations

Benefits and Perks

• Competitive salary and benefits package
• A shaping role in an emerging dual use company
• Opportunity to work with a highly innovative, international, and dynamic team
• Room for professional growth and development
• Participation in the company's success, with access to regular events, knowledge exchange and meetups
