Key Responsibilities

You play an active role in building a sovereign private cloud in our own data center consistently based on open-source technologies. In the initial phase, your focus is on evaluating and selecting suitable components through proof-of-concept implementations. You will work closely with modern, automated infrastructures and actively contribute to the open-source community.

💼 Your mission – or, in other words: your tasks

  • You build and operate a reliable, open-source-based private cloud.
  • You conduct proof of concepts, evaluate technologies, and make well-founded architectural decisions.
  • You develop and run our infrastructure as code (IaC) and design efficient CI/CD pipelines.
  • You establish observability solutions and continuously drive automation forward.
  • You actively contribute to the open-source projects we use (upstream contributions).
  • You analyze and resolve complex incidents at the second and third support levels.
  • You create and maintain clear, sustainable technical documentation.

Skills

🧠 What you bring to the table – besides the desire to make a difference

  • You confidently administer Linux (networking, storage, systemd, performance) and work with infrastructure-as-code tools (e.g., Ansible, Terraform/OpenTofu).
  • You can code (e.g., Python, Go, or Bash) and are familiar with container and orchestration platforms like Docker/Podman and Kubernetes.
  • You are proficient with Git and experienced in open-source workflows (pull requests, code reviews, issue tracking).
  • You have hands-on experience with open-source cloud, virtualization, or storage solutions (e.g., OpenStack, Proxmox, Ceph).
  • You bring on-premise experience, including bare-metal provisioning (e.g., MAAS, Ironic, PXE, Redfish) and data center networking (e.g., spine-leaf, BGP-EVPN, VXLAN, SDN).
  • You are familiar with observability and CI/CD tools (e.g., Prometheus, Grafana, OpenTelemetry, GitLab CI, GitHub Actions).
  • You have exposure to compliance frameworks (e.g., BSI C5, ISO 27001) and understand open-source licensing.
  • You work in an open, collaborative way and bring a strong open-source mindset.
  • You take a pragmatic, technology-agnostic approach and are comfortable working across the full stack.
  • You are fluent in English, both written and spoken; German language skills are a plus.

What we offer

  • We bring you on board, individually and with a personal mentor at your side.
  • Your job with us is challenging, varied and independent, but never boring.
  • We have flat hierarchies, a strong feedback culture and regular performance reviews.
  • Do you have important private appointments? - No problem! Flexible working hours and the option to work hybrid give you maximum flexibility.
  • But would you prefer to work with like-minded people in the office? Height-adjustable desks, at least one large monitor per workstation, space to meet, but also to retreat, are just some of the features of our state-of-the-art offices.
  • We celebrate together and do sport together. Whether as a hobby or when taking part in amateur races - we are happy to sponsor you and your colleagues to take part in sporting events! You can get the necessary equipment for this in our company's own DATAGROUP store!
  • We have also special leave days
  • Company health insurance
