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

About The Role

We are seeking a Senior Mechanical Engineer to build our rugged, high-performance robotic vehicles. In this role, you will transform our robotic platforms into complete, field-ready systems that provide critical capabilities to users in demanding environments. In this hands-on role, you’ll guide designs from concept to deployment, integrating complex payloads and ensuring our systems perform flawlessly under the toughest conditions.

You will be shaping the physical hardware that makes a real-world impact. What You’ll Build Lead the system-level mechanical design for our rugged, off-road robotic platforms. Spearhead the mechanical integration of sophisticated payloads, from sensors and cameras to manipulators.

Develop robust solutions for mounting, protecting, and packaging hardware to withstand shock, dust, water, and heat. Define and validate mechanical interfaces that ensure reliability in the field, not just in the lab. Collaborate closely with our electrical and software teams to create fully integrated, high-performance systems.

Drive a cycle of rapid prototyping, hands-on testing, and continuous improvement. Balance performance, usability, weight, cost, and manufacturability to deliver optimal designs. Guide your designs from the initial concept through to final production.

What You Bring A track record of 5+ years building and shipping real-world mechanical systems in fields like robotics, automotive, or machinery. Proven experience in complex system integration, moving beyond the design of standalone parts. A holistic approach to design, considering electrical integration, stress, and spatial constraints in harsh, dynamic environments.

Proficiency in CAD as a tool for creating elegant solutions (we use Autodesk Inventor, but your skills are what matter). Practical knowledge of common fabrication methods, including CNC machining, sheet metal, and welding. A hands-on, pragmatic approach with a bias for action and tangible results.

The ability to take ownership and drive projects forward, adapting to a fast-paced, high-growth environment. Fluency in English (German is a plus). A degree in Mechanical Engineering, Mechatronics, or a related field.

Please note: You do not need to meet every single requirement to apply. We welcome motivated candidates who are eager to grow into the role and develop their expertise further.
