System Administrator / Site Reliability Engineer (f/m/d)

With our strong brands GMX, WEB.DE and mail.com and over 43 million active users, we are the leading email and communications platform in Germany, Austria and Switzerland. From this strong market position, services and apps are developed that simplify users' digital lives - from office tools and cloud solutions to personal ID management.

Your Tasks

Do you have a passion for the administration of complex and highly available infrastructures and applications? Do you want to make a real difference in a highly digital and agile environment with flat hierarchies? Then we are looking for you! We have more than just a job waiting for you: you can expect cutting-edge technologies such as Kubernetes or Kafka as well as the opportunity to use your skills and ideas to drive topics forward and develop yourself individually. As a System Administrator (f/m/d) you ensure that millions of customers can access their emails, news and cloud data via our websites and mobile apps.

• You will ensure the smooth, reliable operation of our products, which are used millions of times a day, in our in-house data centers. You will also continue to develop our platforms in terms of stability and performance.
• You will act as an interface between software development and the platform teams, working with them to make technology decisions and define service level objectives.
• You develop infrastructure as code, e.g. as part of Gitlab CI/CD pipelines, Helm Charts or Docker container images.
• You constantly improve our observability infrastructure to uncover potential sources of error using tracing and metrics and ensure the reliability of our products and the protection of our customer data through suitable tests, monitoring procedures and analysis tools.
• You will work on your own projects as part of so-called "slack days" or try out new technologies on prototypes.
