We are currently looking for people who want to help us build a sovereign European cloud platform from the ground up - creating a real alternative to global hyperscalers. We are developing a complete PaaS stack based on Kubernetes and open source technologies. From serverless and managed databases to MLOps, monitoring and observability. By joining us, you become part of a team that designs the foundations of the platform rather than maintaining a finished product. We work in a full-ownership model, where every architectural decision stays with the product for years. This is a place for people who want to genuinely influence the shape of the European cloud.

Role

A key DevOps engineer in the PaaS Platform team, responsible for the operational maintenance and development of the platform. You will work on the Kubernetes cluster lifecycle, GitOps pipelines, CI/CD, and the operational stability of the platform. You will bridge the dev and ops worlds - ensuring that what the team builds is ready for deployment, observable, and easy to maintain. Your daily work directly impacts how fast we ship and how stable the platform is.

Your responsibilities:

• Kubernetes cluster lifecycle: provisioning, upgrades, scaling, decommissioning.
• Implementing and maintaining tools and solutions supporting platform operations.
• Maintaining and developing GitOps pipelines for the platform.
• CI/CD: build pipelines, integration test platform.
• Implementing deployment and rollback standards defined for the platform.
• Participating in on-call rotation for critical platform incidents.

Requirements:

• DevOps Engineer with practical experience operating production-grade Kubernetes infrastructure.
• Experience with GitOps (ArgoCD/Flux) in production - maintaining and developing pipelines.
• Strong knowledge of Go or Python.
• Experience with Infrastructure as Code - Terraform, Ansible or similar tools.

Nice to have:

• Experience with Kubernetes cluster upgrade paths - rolling upgrades, certificate rotation.
• Experience with Harbor, OpenBao, or similar tools.
• Experience designing GitOps pipelines for multi-tenant platforms.
• Experience building custom Kubernetes operators.
• Experience with full release management - from builds through integration tests to production deployment.
• Proficiency with AI-assisted development tools (Claude Code) as a natural part of daily engineering work.

Why join us:

• Building a cloud platform: You help create a modern ecosystem from scratch, supporting Europe’s space industry, climate research and scientific projects with real impact.
• Autonomous team: You join a newly formed group operating like a startup within a stable, well-resourced organization.
• CNCF technologies in production: You work with Kubernetes, KNative, Cilium, ArgoCD, Kubeflow and other open-source projects, with opportunities to contribute.
• Real influence: You have a voice in architectural and product decisions, and your ideas genuinely shape the direction of the platform.
• AI-native workflow: We use tools like Claude Code daily - not as an experiment, but as an integral part of engineering work.
• Autonomy and stability: We offer flexibility in organizing your work, transparent collaboration principles, and stable employment with competitive compensation.
• Benefits package: Private medical care, Multisport, life insurance.
• Language classes available.
