QA Engineer

Role Overview

We're looking for a hands-on QA Engineer who enjoys working at the intersection of software and hardware - someone equally comfortable digging through code and pull requests as they are physically testing a machine. This is a role for someone who likes to understand why something breaks, not just that it broke.

Tech Stack

• Python
• pytest / unittest
• C#
• xUnit / NUnit / MSTest
• Git
• Raspberry Pi
• Linux/ARM
• RVM hardware
• Azure Service Bus
• REST API

Responsibilities

• Design and execute test scenarios - functional, regression, and integration
• Physically test RVM (Reverse Vending Machine) through its full operational cycle: bottle/can acceptance, voucher dispensing, integrator communication
• Test changes based on pull requests and link bugs to specific code changes
• Write and maintain automated tests in Python (pytest / unittest) and C# (xUnit / NUnit / MSTest)
• Work with Git - checking out branches, running test builds, flashing builds onto the test machine
• Analyze logs and reproduce reported issues
• Write clear, structured bug reports (steps to reproduce, expected vs. actual behavior) and verify fixes
• Maintain pre-deployment checklists and test documentation

Requirements

• Experience in software testing (manual; automation is a plus)
• Comfortable working with Git - branching, pulling, running builds
• Ability to read code in Python and/or C# well enough to connect a bug to a change
• Willingness to work hands-on with physical hardware - connecting, operating, and observing device behavior
• Attention to detail, independence, and a methodical approach
• Clear and precise bug reporting

Nice to Have

• Experience writing automated tests in Python (pytest / unittest) or C# (xUnit / NUnit / MSTest)
• Familiarity with Linux / Raspberry Pi, working via console or SSH
• Experience with issue trackers (Jira, Linear, etc.)
• Background in testing embedded or hardware-integrated systems
• Basic hardware diagnostics knowledge (serial communication, scanners)

What's in it for you?

• Join for a role, stay for the development: More than 40% of our team is working with us longer than 5 years.
• Explore diverse domains, projects and modern technologies through internal mobility.
• Learn from the best: Almost 60% of all our colleague has over 10 years of professional experience.
• Flexibility: Work fully remotely, full-time from our office in Wroclaw or in a hybrid model.
• Practical benefits: private medical care, life insurance, sport card, English and German classes in small, online groups.
