MediaMarktSaturn Plattform Services GmbH is seeking a Platform Engineer to build and scale a key digital growth engine across Europe. You’ll operate the Google Cloud / GKE platform with a focus on reliability, security and scalability, collaborating with a cross‑functional team.

You’ll automate infrastructure with Terraform and GitOps (Flux), enhance CI/CD with GitHub Actions, and improve observability using Prometheus and Grafana.

Formación

• Independent work style with strong ownership and clear communication.
• Hands‑on experience operating Kubernetes in cloud environments.
• Comfort with GCP (IAM, networking, clusters) and Terraform-managed changes.
• Experience with CI/CD systems (GitHub Actions) and GitOps workflows.
• Strong focus on monitoring, alerting, and system debuggability.
• Ability to contribute to development with TypeScript/Node.js.
• Understanding of modern backend architectures (e.g. NestJS, REST/GraphQL, Pub/Sub, MongoDB, Redis).
• Trade-off‑oriented thinking with explicit decision‑making.

Responsabilidades

• Build and operate our Google Cloud / GKE platform with reliability, security, and scalability.
• Manage infrastructure as code using Terraform and GitOps (Flux).
• 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.
• Develop and scale the marketplace platform for third‑party sellers.
