Senior Mechanical Engineer - UGVs & Payload Integration

Senior Mechanical Engineer - UGVs & Payload Integration

ARX Robotics

Munich, Germany

About the role

We’re building rugged, high-performance off-road robotic vehicles and we’re looking for a Senior Mechanical Engineer who wants to turn vehicles into real-world systems that deliver critical capabilities to soldiers in the field.

In this hands-on role, you’ll take ideas from concept to deployment, integrating complex payloads, and ensuring our systems perform under the toughest conditions. This isn’t just CAD work. You’ll be shaping systems that make a real difference on the ground.

Your Profile

• 5+ years building real mechanical systems (robotics, automotive, machinery, or similar)
• Think like a user: optimize designs for field performance, serviceability, and real-world operations
• You’ve integrated complex systems, not just designed standalone parts
• Design systems with a keen eye on electrical integration, mechanical stresses, and spatial constraints under dynamic operation in harsh environments
• Strong CAD skills (Autodesk Inventor preferred), but you know CAD is just a tool
• You understand fabrication in the real world (CNC, sheet metal, welding, etc.)
• Hands-on, pragmatic, and biased toward action
• You take ownership and don’t wait for perfect specs
• Comfortable working in a fast-paced, sometimes messy startup environment
• Strong problem-solver who can debug issues across disciplines
• Fluent in English (German is a plus)
• Degree in Mechanical Engineering, Mechatronics, or similar

What You’ll Do

• Design and build mechanical systems for off-road robotic platforms, leading the system design, not just the parts
• Own the design and integration of complex payloads (sensors, manipulators, radars and cameras) into and onto UGVs
• Figure out how to mount, protect, power, and package payloads under real-world constraints (shock, dust, water, heat)
• Define mechanical interfaces that actually work outside the lab
• Work side-by-side with electrical and software engineers to make full systems function reliably
• Rapidly prototype, test, break, and improve designs
• Make smart trade-offs between performance, usability, weight, cost, and manufacturability
• Take designs all the way to production.
