At Xelon AG, we deliver secure, scalable, and automated Swiss cloud infrastructure for the next generation of digital services. From IaaS to SaaS, our platform powers workloads in regulated industries like finance, insurance, public services, and tech. Our solutions—Xelon Cloud, Xelon Secure+,Xelon HQ and CloudDeck—combine automation, sovereignty, and simplicity in one ecosystem.

We’re on a mission to become the #1 Swiss Cloud Enabler, and we’re growing a team of people who want to shape the future of cloud infrastructure and software operations.

Your Mission

As a Cloud Engineer in our IT Operations/Platform team, you will operate and improve our multi-hypervisor cloud platform and adjacent services. You’ll handle day-to-day reliability work, automate repetitive tasks, resolve customer-impacting incidents, and keep our backup and DR posture strong. You’ll collaborate closely with IT Ops, Platform Engineering, Networking, and Support.

This is a hands-on role with clear ownership. You’ll rotate in on-call, drive fixes end-to-end, and contribute to runbooks and documentation.

• Keep DR replication healthy and ready; spot-check statuses and resource pools.

Images / ISOs / Templates / Operating Systems

• Resolve ISO mounting issues and maintain image/template hygiene and lifecycle.
• Operate, patch and maintain Windows & Linux systems.

Virtualization & Platform Ops

• 3+ years hands-on in system administration, infrastructure, or cloud engineering.
• Strong Linux administration; comfortable on the CLI for diagnostics and remediation.
• Practical experience with virtualization: VMware vCenter/vSphere/ESXi and/or Proxmox (KVM).
• Familiar with networking (VLANs, routing basics) and storage concepts.
• Backup/DR exposure: Acronis and/or Veeam in production environments.
• Automation mindset: scripting with Shell; familiarity with Ansible; Python is a plus.
• Incident management: calm under pressure, structured troubleshooting, clear documentation.
• Communication: fluent in German and English.
• Location: based in Switzerland (hybrid/onsite as needed), able to participate in on-call.

Bonus Points

• Containers and orchestration: Docker, Kubernetes.
• Experience in regulated environments (ISO 27001, SOC 2) and access control best practices.
• Observability: Prometheus, Grafana, ELK/Opensearch; cert/PKI operations.
• WAF/Firewall exposure and customer-facing communication in incidents.
• Relevant certs: RHCE, CKA, VCP, LPIC (or equivalent)

• A technical role with clear ownership and room for growth in a Swiss tech scale-up.
