UX / UI Designer – App & Web (m/f/d)

UX/UI that’s used every day. And truly creates value.

As a UX/UI Designer, you’ll become part of a fast-growing tech company and work on Aufmaster, the leading app for digital cable documentation.

At Aufmaster, you design user experiences for real doers and skilled tradespeople—people who get things done every day and rely on software that simply works in demanding, real-world conditions. Our solution connects construction sites, warehouses, and offices in real time and is already used in over 34 countries worldwide.

A key differentiator of Aufmaster is the combination of software and a globally unique smart cable length measurement device.

This is exactly what makes UX/UI at Aufmaster so exciting: data is generated directly by 1,000+ customers on construction sites and in warehouses around the world and must be instantly understandable, clear, and reliable within the app. Your work ensures that complex technology stays in the background while users experience smooth, intuitive workflows—from measurement to documentation.

You’ll be a core member of the product team, working closely with Product, Development, and Customer Success. You contribute your own ideas, receive continuous feedback, and iteratively improve the user experience—always focused on real-world use cases and tangible value.
