Role: Windows Patching Lead
Location: Toronto, ON
ROLE SUMMARY
10+ years in Windows Server/desktop administration and patching; 4+ years as tower/pod lead
The Windows Patching Tower Lead (Onshore) is the subject matter expert and client-facing lead for all Windows patching across a 190,000+ endpoint estate. This individual owns the full Windows patch lifecycle — SCCM/MECM/WSUS/Intune/Tanium-driven wave execution, GPO management, reboot orchestration, and compliance reporting — while acting as the primary Wintel interface to client L2/L3 teams and application owners during Canada business hours and weekend change windows.
ROLE IN THE OPERATING MODEL
▸ Tower/pod lead and subject-matter expert for Windows patching — owns execution, quality, and compliance for the Windows tower
▸ Primary Wintel interface to client L2/L3 engineers and application owners during Canada hours and weekend windows
▸ Coordinates app-owner sign-off post-patching and owns Windows tower compliance reporting to the Patch Service Lead
▸ Operates as the Windows execution layer under client direction; gold image/packaging engineering remains client L2/L3 owned

▸ Manage SCCM/MECM deployment rings, collections, maintenance windows, WSUS approvals, and GPO-driven patch policies across servers and end-user devices
▸ Run pre-flight checks — disk space, connectivity, pending reboots, backup confirmation — and reboot orchestration with post-patch smoke tests
▸ Coordinate application-owner sign-off and change-window adherence; track compliance via Tenable/Qualys and remediate non-compliant assets
▸ Update CMDB patch levels, close vulnerability tickets, and maintain KEDB; perform RCA and rollback (KB uninstall) for failed patches
▸ Manage EOL/EOS tracking for Windows versions; flag end-of-support risks to the Patch Service Lead
▸ Own Windows tower compliance reporting; present KPIs and exception summaries to the Patch Service Lead for governance reviews
▸ Coordinate with client NOC during weekend change windows; manage escalation to client Wintel L2/L3 within agreed SLTs
TECHNICAL ACTIVITIES FOR THE SCOPE
▸ Execute monthly Patch-Tuesday and out-of-band patch cycles via SCCM/MECM, WSUS, Intune, and Tanium across Windows Server 2016–2025 and Windows 10/11
▸ Configure and manage SCCM/MECM collections, deployment rings, WSUS approval policies, and GPO-driven patch rollouts
▸ Run pre-flight readiness checks (disk, connectivity, pending reboots, backup), reboot orchestration, and post-patch smoke tests
▸ Track compliance posture via Tenable/Qualys; remediate non-compliant assets and close vulnerability tickets in ServiceNow
▸ Author and submit RFC/CAB documentation for Windows patch waves; coordinate maintenance window scheduling
▸ Perform KB uninstall rollback for failed patches; document RCA and update KEDB
