Role Overview

We're looking for a developer who can take ownership of a topic end-to-end — from understanding the problem, through design and implementation, to verifying it works on the actual machine. The core system runs on a Reverse Vending Machine (RVM), a physical device that accepts bottles and cans. You will work on the Python core running on Raspberry Pi and surrounding C# tooling and integrations.

Tech stack: Python 3.11 · C# / .NET · Raspberry Pi · Linux/ARM · PyQt5 · Azure Service Bus · Firebase · REST API · Git · serial / evdev · HTML / JS

Responsibilities

• Develop and maintain the core control system for the RVM — Python on Raspberry Pi (Linux/ARM)
• Build and maintain supporting tooling and integrations in C# / .NET
• Integrate with external systems via REST API, Azure Service Bus, and Firebase
• Handle hardware communication - serial port, scanners (evdev), and peripheral devices
• Work on the touch UI in PyQt5 and contribute to the growing web UI layer (HTML/JS)
• Debug production issues — analyze logs, reproduce problems, and fix root causes
• Write tests (pytest / unittest) and verify behavior before deployment
• Work in Git with branches, pull requests, and meaningful commit messages

Requirements

• Solid Python experience (3+ years commercial)
• C# / .NET proficiency and ability to independently write and maintain production code
• Self-sufficiency and ownership mindset
• Habit of writing tests and verifying code before release
• Good Git practices and experience with pull requests
• Experience with REST API integrations and JSON
• Ability to navigate and understand a large, existing codebase
• Logical, independent approach to debugging and problem-solving

Nice to have

• Experience with Linux / Raspberry Pi and devices running 24/7
• Hardware communication: serial, evdev, USB
• Azure Service Bus / message queues, Firebase
• PyQt5 or other desktop GUI frameworks
• HTML / JS for web UI work

What's in it for you?

• Long-term cooperation and internal mobility opportunities
• Collaboration with experienced professionals
• Flexible work model: remote, office, or hybrid
• Private medical care, life insurance, sport card
• English and German classes in small online groups
