Job summary

MediaMarktSaturn Technology is seeking a skilled platform engineer to own and operate our cloud-native stack in Barcelona. You will manage a GKE-based platform, implement infrastructure as code with Terraform, and advance GitOps workflows to drive reliable deployments and scalable services.

Join a distributed team focused on observability, performance, and self-service tooling such as TypeScript utilities and CLI tools.

Qualifications

• Hands-on experience operating Kubernetes in cloud environments and understanding of real-world failure modes.
• Comfort with GCP (IAM, networking, clusters) and infrastructure changes managed via Terraform.
• Experience with CI/CD systems (ideally GitHub Actions) and GitOps workflows.
• Strong focus on monitoring, alerting, and system debuggability.
• Ability to contribute to development when needed (TypeScript/Node.js, pipelines, CLI tools).
• Understanding of modern backend architectures (NestJS, REST/GraphQL, Pub/Sub, MongoDB, Redis).
• Trade-off-oriented thinking with explicit decision-making.

Responsibilities

• Build and operate our Google Cloud / GKE platform with a focus on reliability, security, and scalability.
• Manage infrastructure as code using Terraform and GitOps (Flux).
• Make deployments boring: predictable, reproducible, and safe.
• Improve CI/CD pipelines with GitHub Actions and automate where it adds leverage.
• Ensure strong observability using Prometheus and Grafana.
• Think of the platform as a product: reduce friction, enable self-service, and set pragmatic standards.
• Debug production issues and focus on long-term fixes, not workarounds.
• Build small tools or automation in TypeScript/Node.js when it’s the best solution.
