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, maintainability, and observability, and raising the overall quality bar through clear, practical feedback.
Engage deeply in technical problem solving while acting as a quality mentor, driving root cause analysis and defect prevention, and promoting engineering best practices such as TDD/BDD, effective test design, and continuous improvement of tooling and processes.
The essential requirements of the job include:
Masters/Bachelor’s degree in Computer Science or Software Engineering with a minimum of 5 years of experience; ISTQB certification is an advantage.
Strong C# development experience using Visual Studio and unit testing frameworks such as MSTest and/or NUnit; familiarity with GitHub Copilot is an advantage.
Proven ability to create test plans and test cases, automate tests, and design automation frameworks for non-UI applications and services.
Experience working in agile environments and using Azure DevOps to manage and track work.
Hands-on experience with API and UI testing, and familiarity with tools such as SpecFlow, Postman, FIT, load-testing tools, TestComplete, Selenium, or similar.
Solid understanding of FDD, TDD, and BDD principles, with experience building and maintaining CI/CD pipelines in Azure DevOps.
Excellent communication skills, with the ability to influence technical decisions, collaborate effectively with development teams, and drive open issues to resolution.
It would be a plus if you also possess previous experience in:
Experience in the field of laboratory automation / robotics and control theory.
Familiarity with software development processes for a regulated environment (ISO13845 and ISO62304).
