About the Role

As a Site Reliability Engineer, you will be responsible for ensuring the stability, performance, and scalability of mission-critical systems. You will play a key role in the design, implementation, and maintenance of a highly reliable and efficient infrastructure, leveraging expertise in modern monitoring, observability, and cloud-native technologies.

Responsibilities

• Design, build, and operate a high-performance monitoring stack based on Prometheus, Grafana, Loki, and Alertmanager for distributed Fog and Edge infrastructures.
• Develop specialized dashboards for monitoring hardware health, resource utilization, and network connectivity.
• Design and implement alerting strategies for autonomous operating models, disconnected, and air-gapped environments.
• Implement local data retention concepts, log rotation mechanisms, and efficient data management strategies.
• Continuously optimize the performance of the monitoring stack considering limited CPU, memory, and storage resources.
• Integrate Kubernetes monitoring solutions, analyze operational and performance metrics, and identify optimization opportunities.
• Automate the deployment and management of monitoring components using Infrastructure as Code (IaC) principles and YAML-based configurations.
• Contribute to the continuous evolution of a robust, scalable, and highly available observability platform for modern Edge and Fog computing environments.

Requirements

• Strong experience with Prometheus, including PromQL, Federation, Remote Write, and Local Retention Management.
• Advanced knowledge of Grafana, including dashboard development, alerting, and provisioning as code.
• Experience with Loki, including LogQL, retention management, and compaction.
• Strong knowledge of Alertmanager, including standalone routing, alert inhibition, and escalation/notification strategies.
• Experience in monitoring and operating Kubernetes environments.
• Solid understanding of container platforms and cloud-native architectures.
• Experience working in resource-constrained environments.
• Experience with optimization of CPU, memory, and storage utilization.
• Understanding of offline, air-gapped, and disconnected operating scenarios.
• Advanced proficiency in YAML.
• Strong understanding of IT security principles and security awareness.
• Strong analytical and structured approach to problem-solving.
• Experience in Site Reliability Engineering (SRE) or infrastructure operations.
• Excellent German language skills, both written and spoken (C1 level).
