With its business applications, IONOS is one of the leading hosting and cloud applications providers in Europe. With our state-of-the-art technologies, we convince more than 8 million customers in many different countries every day. 

Your Tasks


  • The IONOS online store is the first thing our customers see when they look at IONOS. You ensure that our customers are convinced by our quality and honesty, in that what they ordered is what they get.
  • For our existing customers, the Control Panel is the central point for managing their data and products. Other internal applications such as Login or the Data Center Designer connect us closely with them.
  • You work in an agile, interdisciplinary team in which everyone takes responsibility for the collective result. 
  • You analyze requirements and possible solutions together with development and adapt the use of automated scripts and tools to the requirements.
  • Your focus is on the design and implementation of automated tests, e.g. for regression tests of the frontend or for API tests. You will develop the tests from initial manual approaches to deployment in Docker containers of a Jenkins pipeline.
  • You are transparent at all times with regard to your planning and results and exchange information with internal and external project partners.
  • We as colleagues in Quality Assurance are constantly developing, exchanging ideas with each other and are available to internal customers as consultants. We are the back-up for the development and ensure a reasonable test coverage using appropriate technologies as well as a clean documentation of the test progress.

We appreciate


  • Do you like handling complex tasks? You are not blinded by first impressions and can change perspectives? You love to "break" things to see how they work? You are curious and persistent?
  • You have a degree in computer science or a similar field and your heart beats for quality and testing. You may already have professional experience in test management, ideally by working on IT projects.
  • You know how to design and manage test cases, and if the requirements aren't quite final yet, you'll make sure they are. You know that test automation is not everything, but without automation not much is possible. You find bugs in development, not in the developer.
  • You make a task yours until it's done. You approach your colleagues and actively exchange ideas with them. You think outside the box and are open to new topics and technologies.
  • You are familiar with front-end developer tools and Javascript / Node. You have heard of Swagger and know Docker. You move easily in a Linux environment. Experience with Cypress would be an absolute plus.
  • Support us to make our customers successful. Get to know us and complement us as a Test Manager in the area of Shops & Customer Platforms. Become a formative part of a dynamically acting area, which will surprise and challenge you again and again.
