Cloud Infrastructure Engineer (m/w/d) – full remote möglich

As a Cloud Infrastructure Engineer, you will build, operate, and optimize our cloud infrastructure, ensuring the stability, scalability, and future-proofing of our technical foundation. You will be responsible for the central building blocks of the infrastructure – from compute to storage, content delivery, DNS, and network security – and will hold the main control levers in the "engine room". You will deal with the design of network architecture, scaling, and high availability, and you will build the infrastructure in such a way that it remains reproducible, automated, and easily traceable. You will keep an eye on operational costs, identify optimization potential, and ensure that our cloud environment is not only performant but also cost-effective. You will be actively involved in building, moving, and migrating our infrastructure – including clearly planned transition and data migration phases, so that technical transitions don't become a "blind flight". This position can be held 100% from home. We are open to part-time work; ideally at least 30 hours per week. You have a technical university degree, appropriate professional training, or practical IT work experience, as well as at least 3 years of experience in cloud infrastructure or IT infrastructure. You are proficient in at least one public cloud platform such as Google Cloud or AWS, ideally both, and are familiar with Kubernetes, networking, as well as DNS/CDN, e.g., Cloudflare or CloudFront. "Infrastructure as Code" with Terraform and scripting, e.g., in Python or Bash, are part of your toolkit. Experience with migrations or cross-system architectures is a clear advantage and will help you get up to speed with our systems faster. When dealing with repetitive tasks, you immediately think of automation and want to create infrastructure neatly, stably, and reproducibly, rather than "assembling" it manually. Your interest in AI tools (ChatGPT, Claude, Gemini) or ideally even initial experience with AI agents such as Codex, Claude Cowork, or Gemini Spark is welcome and can be put into practice. To integrate successfully into our team, you must have a C1 level of German. We are an open and ambitious team of over 500 employees who are truly customer-oriented and enjoy their work. We still have a startup atmosphere even after more than 10 years, which, in addition to a legendary fruit basket, offers a variety of benefits such as a tax-advantaged shopping card, bike leasing, and health courses (e.g., yoga, back training, and mental health) – both online and in the office. Depending on the area of activity (and this applies to at least 75% of all company areas), we offer all our colleagues flexible working hours and the option to work from home. We see ourselves as a closely knit team with an atmosphere of cooperation rather than competition. Outside of work, we organize events such as beach volleyball in the summer, picnics, cooking evenings, or kayak tours.
