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

In this role, you will develop key cloud services of the platform: DBaaS, Docker Registry, and secret-management systems (Vault / Key Manager). You will work in a full-ownership model - from Kubernetes integration, through API design, to documentation and production reliability. You will have a real impact on how customers work with data and security in a cloud environment.

Your responsibilities

• Full ownership of platform services: development and maintenance of DBaaS (Severalnines CCX), Registry (Harbor), and Vault / Key Manager in a “you build it, you own it” model - from implementation, through APIs and documentation, to operational stability.
• Integration with shared services: connecting platform services with IAM, billing and quota systems developed by the Common Services team.
• End-to-end delivery: working across the full delivery lifecycle - from Kubernetes integration and API endpoint design to final documentation.
• Engineering collaboration: participating in code reviews and pair programming, jointly shaping technical and quality standards.

Requirements

• Experience building applications on Kubernetes - we are looking for an engineer who has worked with K8s and wants to grow into platform engineering.
• Knowledge of Go and Python - ability to write clean, testable code.
• Understanding of REST API design: CRUD, error handling, versioning.
• Kubernetes fundamentals: deployments, services, ConfigMaps, Secrets, RBAC.
• Experience with AI-assisted development tools: comfortable using Claude Code, Copilot and similar tools as a natural part of daily engineering work.

Nice to have

• Operational experience with databases: PostgreSQL, MySQL.
• Knowledge of Harbor or other registries.
• Experience working with HashiCorp Vault on Kubernetes.
• Exposure to the Kubernetes operator pattern.
• Knowledge of Terraform (even at module-writing level).
• Experience with containerization and CI/CD: Docker, pipelines.

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.
