Junior Backend (Python) Engineer

We’re looking for a Junior Backend (Python) Engineer to join our team.

Work Location: Poland (Krakow), Slovakia (Kosice) or Czechia (Prague).
Hybrid: 2+ days per week in the office, the rest remote.

The Mission
We are building a complex, real-time ecosystem for micromobility and logistics systems sim—where split-second logistics meet seamless user experiences. We need a Junior Backend (Python) Engineer to work on the development of our Customer Mobile Web App and our high-utility Internal Admin Panels.

You’ll be the bridge between the sleek, high-performance interface our users see and the robust, scalable Python services that power the logic.

Key Responsibilities
Mobile-First Frontend: Architect and scale our React-based mobile web application, ensuring 60fps performance and offline-first capabilities.
Operational Control Centers: Build dense, data-heavy Admin Panels that allow our operations team to monitor real-time logistics, manage users, and handle complex dispatching.
Scalable Backend: Design and maintain performant APIs using Python (FastAPI/Django) to handle high-concurrency event streams.
End-to-End Ownership: From database schema design to CSS transitions, you’ll own the entire feature lifecycle.

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.
Will be plus Led transformation of standalone product into scalable SaaS platform.
