About the Role

As a Site Reliability Engineer, you will be responsible for the stability, security, and performance of our complex, distributed systems. You will work closely with development teams to design, implement, and operate scalable and reliable infrastructures, as well as automate and optimize processes.

Responsibilities

• Technical Level 2 support with direct customer contact.
• Maintenance of monitoring, logging, and alerting solutions (e.g., Prometheus, Grafana, Loki) for proactive problem detection in shift operations and contribution to solving complex issues in distributed systems.
• Troubleshooting networks (LAN/WAN/VPN, DNS, DHCP) and storage systems (File/Object/Block); provision and operation of highly available services on Linux and Kubernetes (Helm charts).
• Setup and maintenance of Infrastructure-as-Code, automation, and playbooks with Ansible, Terraform, GitLab CI/CD, Argo CD, and scripting languages like Bash, Python, and Go.
• Collaboration with development teams to improve processes and deployments, and to ensure smooth integration of new services and applications into our cloud and Kubernetes environment.
• Ensuring stable and secure platform operation, including end-to-end incident management from initial analysis through resolution to post-processing within the scope of problem management.

Requirements

• Willingness to work in a 24x7 shift model (night, weekend, and holiday shifts) with a strong problem-solving and troubleshooting mindset.
• Several years of experience as a Site Reliability Engineer or in a related role (Linux System Administrator, Platform Engineer, DevOps/Infrastructure Engineer, Full-Stack Developer).
• In-depth knowledge of automation tools (e.g., Ansible, SaltStack), monitoring and observability tools (Prometheus, Grafana, Loki), and logging and alerting solutions (ELK Stack).
• Experience with virtualized environments (QEMU/KVM, OpenStack, Proxmox), cloud storage technologies (File, Object, Block), and secure handling of Docker & Kubernetes.
• Very good knowledge in at least one programming or scripting language (Go, Python, Bash) for automation and monitoring tasks.
• Experience in code management (merge conflicts, feature branches, merge requests, CI/CD) is an advantage.
• Experience with RDMA, InfiniBand, and RoCE protocols.
• Deep knowledge in Linux MD RAID (mdadm, sedadm) and LVM.
• Expertise in Linux performance tuning and network stack debugging (ethtool, perf, tcpdump, ibstat, ibtop).
• Practical experience with S3, Ceph, and software-defined networks.
• Experience with established software development practices (code reviews, build processes, packaging, testing).
• Fluent in German and English (at least B2 according to CEFR standard).
