Real Impact - Code That Matters

Your work makes a difference. At Softwarehelden, you’re not just pushing code — you’re building solutions that transform businesses, optimize workflows, and make technology truly work for people. Our tech isn’t just hype — it’s fast, flexible, and built to last.

Cluu - More than a Tech Stack

Cluu is not just another framework — it’s a powerful Virtual Database technology that allows you to develop applications faster and more efficiently than ever. No-Code/Low-Code here doesn’t mean limitations — it means supercharging development so you can focus on real challenges instead of boilerplate.

Code over Calls

We believe in clean code, smart solutions, and fast decisions — not endless meetings. As a developer at Softwarehelden, you’ll have real architectural influence and the freedom to shape the platform instead of just following specs.

Team-Oriented Culture

We have no rigid hierarchies – just genuine teamwork. Everyone helps each other, and no one is left behind. We believe that great ideas don’t come from a top-down approach but from an environment where innovation and creativity thrive together.

Hidden Champion, Max Agility

We combine the agility of a startup with the stability of an established player. No rigid corporate structures — just cutting-edge technology, a highly skilled team, and the freedom to experiment and innovate without red tape.

Innovation? We really Mean It.

AI, automation, data intelligence — at Softwarehelden, these aren’t just buzzwords. You’ll work on real AI-powered solutions that drive efficiency, automate processes, and create smart, scalable applications. Innovation isn’t just a goal — it’s what we do.

31 Days Off – Because We Value Your Time

30 days of vacation – plus a little seasonal kindness: on Christmas and New Year’s Eve, you only need to take half a day off.The other half’s on us.

Work-Life Balance That Actually Works

We track working hours transparently, and every extra hour turns into 1:1 time off. No unpaid overtime, just fair compensation for your time.

Work from Where It Works Best

We love collaboration and quick whiteboard scribbles – and yes, that happens best in person. But we also understand when life calls for flexibility. One remote day per week is our standard – and when life gets in the way, we stay pragmatic.

Oh, and we also take care of the little things — from Pizza Fridays to your gym membership.

We’re looking forward to getting to know you!
