Could you be the full-time Data Center Infrastructure IT Specialist in Toronto, ON we’re looking for?

This job posting represents an existing vacancy.

Take on a new challenge and apply your virtualization and infrastructure expertise in a cutting-edge field. You’ll work alongside a collaborative and innovative team.

You’ll play a key role in ensuring the reliability, performance, and scalability of our data centers. Day-to-day, you’ll work closely with teams across the business, including infrastructure, network, database, and application teams, to deliver secure and well-managed services, while optimizing and evolving our on-prem environments.

You’ll specifically take care of deploying and administering VMware vSphere environments, managing virtualization networking, and administering both Windows and Linux servers, but also implementing backups and disaster recovery plans and testing them periodically.

• Deploying and administering VMware vSphere environments (ESXi, vCenter, clusters, HA/DRS, Lifecycle Manager, templates)
• Managing virtualization networking (vSwitches/distributed switches, port groups, VLANs, NIC teaming/LACP)
• Administering Windows Server (AD, DNS, DHCP, GPO, file/print, clustering) and Linux (SUSE/Ubuntu/RHEL: users, services, systemd, security, patching)
• Operating storage and data services supporting virtualization (SAN/NAS, iSCSI/NFS, multipathing, VMFS, vSAN)
• Automating routine tasks using Power Shell/PowerCLI and/or Bash
• Planning and implementing OS, hypervisor, and firmware patching
• Troubleshooting complex incidents across compute, storage, network, and OS layers
• Maintaining clear documentation (diagrams, SOPs, build guides)
• Engaging with vendors for support cases, licensing, and best practices

We value passion and attitude over experience. That’s why we don’t expect you to have every single skill. Instead, we’ve listed some that we think will help you succeed and grow in this role:

• Degree in IT, Computer Science, or equivalent practical experience
• 7+ years in enterprise infrastructure roles with a focus on server virtualization and data center operations
• Deep experience with VMware vSphere (vCenter, ESXi, clusters, HA/DRS, vDS, templates, lifecycle/patching)
• Strong administration skills across Windows and Linux Server (SUSE/Ubuntu/RHEL)
• Hands‑on experience managing Microsoft SQL Server in production (install/configure, backup/restore, patching, monitoring; HA/DR exposure is a plus)
• Solid grounding in networking concepts and implementation for virtualized and on‑prem environments (VLANs, trunking, LACP, subnets, routing basics, firewalls, VPN)
• Scripting proficiency in Power Shell/PowerCLI and/or Bash for automation
• Experience with storage technologies (SAN/NAS, iSCSI/NFS) and their integration with virtualization
• Strong troubleshooting, documentation, and communication skills
• SUSE Harvester/Rancher experience (HCI operations, upgrades, troubleshooting) is a plus
• Advanced MS SQL Server features (Always On, failover clustering, performance tuning) is a plus
• Backup/DR tools (Veeam, Rubrik, Commvault) and proven DR testing experience is a plus
• Relevant certifications (VCP‑DCV, Microsoft, SUSE, RHCSA/RHCE, Network+) preferred
