## Description

We are growing our team and are looking for a **Mid to Senior Virtualization Engineer** to design, run, and continuously improve the platforms that our critical services depend on. You will own our VMware estate end to end, while working across cloud and the broader infrastructure stack — networking, storage, backup, and automation.

This is a hands-on engineering role for someone who enjoys building resilient, well-documented platforms and helping the wider team level up. You'll work closely with infrastructure, networking, security, and application teams to keep our environments performant, secure, and highly available.

**What you'll do:**

-   Own our virtualization platform by designing, deploying, and operating VMware environments (vSphere / ESXi, vCenter) and alternative hypervisors across on-prem data centers.
-   Handle day-to-day operations including provisioning, capacity planning, patching and upgrades, performance tuning, and lifecycle management of hosts and clusters.
-   Ensure reliability and resilience through monitoring, alerting, backup/restore, and disaster-recovery procedures, while taking part in root-cause analysis of incidents.
-   Automate repetitive tasks using tools or scripting to reduce manual work and enforce consistency.
-   Support our hybrid cloud footprint by integrating on-prem virtualization with public cloud and supporting hybrid and migration initiatives.
-   Contribute across the infrastructure stack by collaborating on compute, storage (SAN/NAS), and network configuration to keep the platform secure and performant.
-   Document and share knowledge through runbooks, architecture diagrams, and standards, while mentoring more junior engineers, especially at senior level.

## Requirements

-   Bachelor'sdegree in Computer Science, Information Technology or a related field.
-   3+ years working with virtualization and enterprise infrastructure.
-   Strong, demonstrable knowledgeof the VMware stack — vSphere, ESXi, vCenter, and clustering/HA/DRS concepts.
-   Good understanding of infrastructure fundamentals: compute, storage (SAN/NAS, iSCSI/NFS/Fibre Channel), and networking (TCP/IP, VLANs, firewalls, load balancing).
-   Experience with at least one public cloud and core cloud concepts.
-   Scripting/automation skills (PowerCLI, PowerShell, Bash, or Python) and comfort with infrastructure-as-code.
-   Familiarity with Linux and Windows Server administration.
-   A methodical, troubleshooting mindset and clear communication in English.

Nice to have:

-   VMware certifications (VCP-DCV / VCAP), Veeam or Citrix/Horizon Certifications.
-   Experience with additional virtualization or hypervisor technologies (Proxmox, Hyper-V, KVM).
-   Exposure to containers and orchestration (Kubernetes, VKS, Docker).
-   Experience with backup and DR tooling (Veeam, Zerto, or similar) and SAN storage platforms.
-   Knowledge of monitoring/observability tooling (Aria Suite, Veeam One, Grafana, Zabbix).
-   Experience in regulated or high-availability environments.

We will offer you a friendly and dynamic working environment, in which you can develop your skills and competencies and a workplace with a strong focus on values and work-life balance.
