Senior Python Test Engineer – Hardware & Test Automation

About the Role

We are looking for an experienced Senior Python Test Engineer to develop automated testing solutions for optical and embedded devices. The role combines strong Python engineering with test architecture, laboratory automation, and hands-on work with physical hardware.

What we offer:

• Opportunity to work at the intersection of Python software engineering, hardware, and test automation.
• Hands on work with physical devices, laboratory equipment, and measurement systems.
• Real influence on test architecture and technical decisions.
• Opportunity to build reusable testing solutions and shared libraries.
• Multisport card.
• Private healthcare.

Zakres obowiązków

• Designing and developing automated tests in Python and pytest for optical and embedded devices.
• Building and maintaining Python-based test suites and shared libraries.
• Automating communication with laboratory equipment and measurement instruments.
• Developing test strategies covering functional, integration, and performance testing.
• Integrating automated test suites with CI/CD pipelines.
• Making architectural decisions and balancing technical trade-offs.
• Participating in code reviews and sharing knowledge with the team.
• Designing manual tests where automation is not yet justified.
