Senior Python Engineer

About the Position

Senior 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

• 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.
• 5+ 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.

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!)
