You're looking for a role where you don't just write code, but shape products? Then you're in the right place with us.

Tasks

• Development and further development of our internal dashboard (Backend + Frontend)

• 30 vacation days
• Flexible working hours and async-first culture - we dispense with unnecessary meetings

We are not a conglomerate with endless coordination loops. At our company, what you bring in counts, not your title. If you're interested in being part of a small, high-performance team that makes a real impact and consistently uses modern tools like AI, we look forward to receiving your application.

Just send us your CV - we don't need a long cover letter. Show us what you've built instead.
