Offer description

We are looking for an experienced Site Reliability Engineer to ensure the stability, scalability, and operational excellence of a Kubernetes-based platform running in a hybrid environment.

The project is entering a pivotal phase, with a major go-live planned for mid-February and a target audience of 75,000 users. User onboarding is already underway, with over 5,000 users connected and 15,000–20,000 expected to be active by year-end. While the system is stable, we anticipate increased activity and new challenges in January, February, and after the go-live—making this an exciting opportunity to make a real impact. The role focuses on performance optimization, scaling strategies, observability, and reliability engineering.

1. Operate and optimize hybrid infrastructure (on-prem & STACKIT)
2. Manage and scale Kubernetes clusters
3. Optimize Helm charts, resource usage, and autoscaling
4. Conduct performance, load, and stress testing
5. Ensure reliability, availability, and monitoring of production systems
