• Build a cloud platform from scratch that supports the European space sector, climate research and scientific initiatives with real‑world impact.
• Join a highly autonomous team operating with startup‑level ownership inside a stable and established organization.
• Work with CNCF technologies in production environments: Kubernetes, KNative, Cilium, ArgoCD, Kubeflow and more.
• Have a real voice in architectural and product decisions.
• Work in an AI‑native engineering environment where tools like Claude Code are part of everyday workflows.
