Infrastructure Engineer (Datacenter & Cloud)

Infrastructure Engineer (Datacenter & Cloud)CMG is looking for a hands-on engineer to run our datacenter, Linux/HPC and Microsoft infrastructure, and to modernize it with Terraform, Packer and cloud. You will report to the VP of IT and Information Security and work with IT, Infosec and the engineering teams that depend on our compute and storage.
Responsibilities
Run datacenter hardware: rack and cable gear, manage firmware, track capacity, and work vendor support cases.
Administer Linux servers and HPC compute nodes, including Entra ID authentication with Himmelblau.
Operate our Proxmox virtualization platform and the storage behind it (Dell PowerScale, TrueNAS).
Build infrastructure as code with Terraform and golden images with Packer, across on-premises systems, Azure and AWS.
Lead the retirement of VMware and Citrix Hypervisor (XenServer), moving workloads to Proxmox or the cloud.
Support Active Directory, Entra ID, Microsoft 365 and Windows servers alongside the wider IT team.
Keep systems hardened and patched, own infrastructure vulnerability remediation, and run regular backup and restore tests.
Handle tier 3 incidents and take part in an on-call rotation.
Within 90 days you handle routine hardware and Linux work independently.
Within 12 months you own datacenter operations and infrastructure as code, VMware and Xen are well on their way out, and restore tests run on a schedule.
This role is based in Calgary with regular on-site datacenter time and an after-hours on-call rotation.
Qualifications
5+ years in systems or infrastructure engineering across Linux and Windows.
Required Skills
Hands-on datacenter hardware experience.
Strong Linux administration and scripting (PowerShell plus Bash or Python).
Practical Terraform and Git experience, including public cloud.
Packer image builds and production virtualization experience (VMware, Xen or Proxmox), including migrating VMs between platforms.
A practical grounding in security hardening: least privilege, MFA, patching and logging.
Preferred Skills
HPC scheduler experience (Slurm, PBS) and scale-out storage.
Security or cloud certifications (Security+, AZ-104, Terraform Associate, RHCSA).
