Senior Mechanical Engineer (m/f/d) UGVs & Payload Integration

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. 

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. 

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 

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
