About the Position

Python Engineer | Join Bluefield Technologies

We are looking for a Senior Backend 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-where split-second logistics meet seamless user experiences. We need a Full Stack powerhouse to lead 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.

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.

Requirements

Education: Follow-up/Higher Professional Education
University education: Bachelor’s degree, Master’s degree
Proven experience in Python and backend development using FastAPI, Django, or Flask.
Strong understanding of geospatial data structures (GeoJSON, latitude/longitude).
Understand principles of cloud native development
Usage of docker for development environment
Familiar with Kubernetes (application lifecycle and environment)
Familiar with Helm charts (their maintenance and usage)
Familiar with ArgoCD, Grafana, Github
Nice to have - familiarity with helmfile
Required Skills:
- 3+ years of experience with Python, primarily in backend development
- Python: Advanced
- FastAPI / Django / Flask
Language skills:
- English: Upper intermediate (B2)

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 a plus: Led transformation of standalone product into scalable SaaS platform.

Why Join Us?

Work on a product with immediate, real-world impact.
A "no-red-tape" environment where your architectural decisions stick.
