Job Technologies

Your role in the team

  • Proxmox and VMware are your daily tools - you use them to provide, optimize, and strategically develop stable and high-performance cloud environments.
  • You provide technical input for architecture, design, configuration, and operation of on-premise and public cloud infrastructures and actively contribute to complex digitization projects.
  • CI/CD, Ansible, Kubernetes & Terraform are more than just buzzwords to you - you use them purposefully, further develop automation concepts, and create scalable infrastructures.
  • Modern infrastructure and DevOps concepts are your thing - you drive the development of our platforms forward and bring new technologies and best practices into the team.
  • Change management? Sure! You continuously develop existing solutions, identify optimization potentials, and implement meaningful improvements together with your team.
  • You think in solutions, not problems. Through our ticket system, you handle complex technical inquiries and incidents in 2nd- and 3rd-level support, coordinate directly with the technical contacts on the client side, and assume technical responsibility for challenging disruptions and escalations.
  • On-call duty is not a hindrance for you. Up to 8-10 times a year, you will be on standby together with a colleague for a week each — of course, with additional compensation.
  • Exchange, development, and team spirit are essential in critical infrastructures. Therefore, we are in the office 3 days a week and can work remotely 2 days a week.
