Who You Are

The Architect: You don't just "write code"; you design systems. You understand how a change in a Python microservice ripples out to the React frontend.
UX Enthusiast: You understand that an Admin Panel requires different UX "muscle" (efficiency and density) than a mobile app (simplicity and speed).
Problem Solver: You’ve dealt with the "hard stuff"-real-time GPS tracking, race conditions in booking logic, or complex state management.
Pragmatist: You balance the need for clean, tested code with the reality of shipping features in a fast-paced environment.

We Offer

Challenging and rewarding tasks with autonomy in a distributed international team.
Motivated colleagues who foster a collaborative environment.
Competitive salary based on your experience and expertise.
20 vacation days + state holidays + your birthday off (for full-time employees).
Sick leave coverage (5 days for full-time employees).
Opportunities for regular business trips abroad.
The longer you are with us, the more interesting benefits you will have! (additional holidays and after 5 years you will receive an extra one month paid holidays!)
