Switzerland

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.

## Tasks

**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.  

**Your Responsibilities**

**Customer Incidents (CSP/JSM)**

*   Triage, troubleshoot, and coordinate incidents; communicate clearly with internal teams and (when needed) customers.
*   Perform urgent restarts and recovery actions in line with runbooks.

**Backups & DR (Acronis, Veeam)**

*   Investigate and remediate backup failures, storage/quota issues, and alert noise vs signal.
*   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**

*   Operate and maintain **vCenter/vSphere/ESXi** and **Proxmox** environments (compute, storage, networking).
*   Monitor host health, certificates, capacity, and performance; address storage warnings.

**Networking (in collaboration with NetOps)**

*   Handle VLAN activations and resolve basic connectivity/no-network cases.

**CMDB & Documentation**

*   Create/update documentation and runbooks in Confluence; keep CMDB entries accurate.

**Projects/Initiatives**

*   Support decommission/migration tasks and platform improvements; contribute to vulnerability remediation follow-ups.

**On-call & Escalations**

*   Participate in OpsGenie/ITMON rotations; update escalation policies and validate alert routing.

## Requirements

*   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)

## Benefits

*   A technical role with clear ownership and room for growth in a **Swiss tech scale-up**.
*   A collaborative team and helpful culture; direct collaboration with engineering, DevOps, and platform.
*   Hybrid work model with flexibility and modern tooling.
*   Competitive salary and equity participation opportunities.
*   A product-driven environment with purpose, clarity, and ownership.
