We are modernizing Müller's complete application landscape — from classic fat clients toward containerized web, mobile, and event-driven integration workloads running on our new GCP-based DevOps Platform with a centrally managed GitLab at its core. As Lead Test Automation Engineer, you build our new test automation team in Bucharest and Ulm from the ground up: you shape the test strategy for this multi-year transformation, set the technical direction, and make quality a built-in property of how Müller ships software.
WHAT CONVINCES US
Several years of hands-on experience in test automation or quality engineering, ideally with first leadership or architectural responsibility — whether as a seasoned lead or a strong senior engineer ready to take this step.
Solid experience with modern web test automation — for example with Playwright, Cypress, or Selenium — and the openness to establish the right framework for our stack.
Good understanding of testing beyond the UI: API testing, integration testing, and ideally first exposure to contract testing or container-based test approaches.
Interest in testing modern architectures — microservices, APIs, asynchronous messaging — and the curiosity to grow into topics like event-driven integration and API management.
Experience with or interest in mobile test automation is a plus — our future stack includes React Native apps.
A pragmatic sense for the test pyramid: knowing where automation adds the most value and keeping test suites lean, fast, and trusted.
Familiarity with CI/CD pipelines and the ambition to make automated quality checks a natural part of the delivery process.
Appreciation for the realities of transformation: legacy applications and their test suites deserve care while the new world is being built — experience with codeless tools such as Ranorex is a plus, not a must.
Enjoyment in building and mentoring a team, and in helping experienced testers grow into modern automation practices.
Clear, approachable communication across engineering, QA, and business stakeholders.
fluent English required; German or Romanian is a plus.
