We are looking for experienced Cloud Operations Engineers with strong backgrounds in Linux, Windows, networking, and cloud environments to join our Customer Operations team.

You will support our Business and Enterprise customers across the full lifecycle of incident handling from initial intake and root cause analysis through to full service restoration. You bring a customer-first mindset and a strong drive to solve complex problems. While we receive requests directly from customers, we operate as an L2/L3 team. You are comfortable managing multiple tasks simultaneously and can set clear priorities even under pressure.

We operate 24/7 across three shifts. You are comfortable participating in shift rotation and being scheduled accordingly. Some of our work touches sensitive areas; you are willing to undergo an extended security vetting process (SÜ2). Our customers communicate in both German and English, and you are equally confident in both.

### Tasks

Act as both technical advisor and ops engineer for Enterprise customers in complex, multi-layered environments
Analyse customer workloads, debug complex incidents, and deliver lasting resolutions or effective workarounds
Automate recurring tasks and problems using scripts, tooling, and AI-assisted solutions
Collaborate with Development and Sales teams to improve overall service quality and platform stability
Work in security-sensitive environments under strict compliance and regulatory requirements
Monitor cloud infrastructure proactively and respond decisively when anomalies arise

### Qualifications

Several years of experience operating cloud infrastructure, Linux, networking, virtualisation (QEMU/KVM), containers (Kubernetes), storage systems, and web APIs
Strong customer-first mindset with a genuine drive to find solutions
Enthusiasm for root cause analysis; log files, traces, metrics and hands-on troubleshooting
Solid network debugging skills across LAN, WAN, VPN, DNS, and DHCP
Familiarity with S3 and storage concepts (file, object, block)
Experience with monitoring and alerting tools such as Prometheus, Grafana, and OpsGenie
Knowledge of common development and deployment tooling: Bash, Python, Ansible, Terraform, Git
Experience with ticketing and documentation systems (Jira, Confluence, or similar)
Scripting and software development skills; experience using AI tools in this context is a plus
Willingness to undergo extended security vetting (SÜ2)
Fluency in German and English
