Current opening

Our client:

A Canadian manufacturer in the Greater Toronto Area, running a continuous production environment supported by a modern in-house IT function.

Intro:

Reporting to the Director of Technology, this role keeps the server and infrastructure estate stable day to day while leading the technical side of the organization's modernization programme - cloud adoption, platform upgrades, and application and data migration. It suits a hands-on senior administrator who wants ownership of the environment rather than a narrow queue, and who is comfortable planning a cutover as well as running the platform afterwards.

Principal tasks and responsibilities include:

• Administering and maintaining the physical and virtual server estate, monitoring performance, capacity and availability
• Owning the Windows Server environment end to end, including Active Directory, Group Policy, DNS and DHCP
• Maintaining storage, backup and disaster recovery platforms, and keeping business continuity processes in place and tested
• Administering Microsoft 365 and the cloud-connected services alongside it
• Planning and carrying out infrastructure upgrades and hardware lifecycle management
• Supporting Azure services across a hybrid estate - virtual machines, storage, networking and identity
• Contributing to cloud migration planning and then implementing it, and monitoring and optimizing cloud consumption and cost
• Leading the technical planning and execution of server, application and data migrations, including cutover and rollback plans
• Moving workloads off legacy platforms onto current ones, and validating migrated data and systems before sign-off
• Supporting ERP, application and wider infrastructure modernization initiatives
• Applying infrastructure security practice: access control, privileged account management, patch management and vulnerability remediation
• Maintaining technical documentation and system architecture diagrams
• Working alongside internal IT staff, vendors and project teams
• Taking part in planned after-hours maintenance and upgrade windows as required

Qualifications and pre-requisites:

• Minimum 7 years of IT infrastructure and server administration experience
• Minimum 7 years managing Active Directory, DNS, DHCP and Group Policy
• Expert-level Azure: Entra ID, virtual machines, storage, networking and App Services
• Experience with SSO, MFA, Conditional Access, RBAC and advanced security policies
• Experience with VMware, Hyper-V or comparable virtualization technologies
• Experience with backup, disaster recovery and business continuity technologies
• Strong understanding of networking fundamentals
• Demonstrated experience leading infrastructure, cloud and ERP migrations
• Microsoft 365 administration experience
• Automation experience with PowerShell, Azure CLI, Terraform or equivalent tooling
• Experience supporting a cloud transformation initiative
• Familiarity with VOIP telephony, label printers and bar code scanners
• Sound understanding of IT service management, and of change and release management procedures
• Able to analyze, evaluate and define needs, and to create and execute implementation test plans
• Strong analytical, problem-solving, organizational and time-management skills
• Excellent communication, customer service and presentation skills, working well independently and as part of a team
• Experience supporting manufacturing production environments is an asset
• Knowledge of budget and vendor management is an asset
