## About the Role

* You have a completed degree in a STEM field, equivalent training, or relevant practical experience in software development or quality assurance.
 * You have solid experience in test automation and can structure it to remain maintainable, reliable, and scalable over the long term.
 * You have practical programming experience with Java and write readable, maintainable test code. Experience with Serenity BDD is a plus; alternatively, you're willing to learn it.
 * You're familiar with testing APIs and microservices and have a good understanding of distributed backend systems and synchronous and asynchronous communication.
 * You're familiar with the fundamentals of event-driven architectures; ideally, you've already worked with Apache Kafka or similar technologies.
 * You have experience with CI/CD pipelines and understand how automated tests are integrated into the development and delivery process.
 * To you, quality means more than running test cases: you identify risks, question existing test coverage, and contribute ideas to improve our testing strategy and automation.
 * You work independently, in an organized and solution-oriented way, and enjoy learning about new technologies and subject areas.
 * You communicate technical and quality-related topics confidently with different stakeholders and adapt the level of detail to your audience.
 * Confident communication in German and English, ideally at B2 level or above

## Description

* You work with developers and product teams to develop a suitable testing strategy for our backend systems and ensure sensible test coverage across different testing levels.
 * You design, implement, and maintain automated tests for our APIs and microservices, ensuring that our test automation remains stable and maintainable as complexity grows.
 * You decide which tests make sense at the unit, API/integration, or end-to-end level, and help avoid duplication between testing levels.
 * You integrate automated tests into our CI/CD pipelines, analyze test results, and help identify errors and quality risks early in the development process.
 * You analyze and debug failed and unstable tests, and continuously improve existing test frameworks and processes.
 * You actively contribute to our quality engineering efforts, identify quality risks with the team, and decide where test automation adds real value.
 * You work closely with developers, product owners, business teams, and other QA engineers, making quality a shared part of product development.
