The Senior Software Engineer - Software Test Developer (f/m/d)

The Senior Software Engineer - Software Test Developer (f/m/d) is responsible for ensuring the quality, reliability, and robustness of software developed by engineering teams. This position reports to the Manager Software Engineering and is part of the R&D Software team located in Munich and will be an on-site role.

In this role, you will have the opportunity to:

• Apply strong C# software engineering skills with quality as a first-class outcome-contributing to design, implementation, refactoring, and code reviews, and validating behavior with effective unit and integration tests.
• Treat tests as real software : build and maintain production-grade test infrastructure (frameworks, utilities, libraries) using SOLID principles and clean architecture, with meaningful coverage and long-term maintainability.
• Collaborate closely with peers during implementation-participating in design/architecture discussions, improving testability and robustness, and driving pragmatic changes in product code and interfaces where needed.
• Leverage and evolve the automation framework by owning its architecture, extensibility, and performance, and by strengthening CI/CD quality gates (fast feedback, reliable signals, flaky-test reduction) using simulations, stubs, and mocks where appropriate.
• Bring a strong quality perspective to code and test reviews, identifying design risks and edge cases across correctness, reliability, maintainabilit
