• Serve as the final escalation point for complex, unresolved incidents involving Active Directory, Exchange, SCCM, SQL Server failover clustering, SharePoint, and other on-premises Microsoft applications.

Infrastructure Management

• Contribute to and maintain knowledge base articles to support consistent, high-quality issue resolution across the support organization.

Client & Stakeholder Support

• Provide advanced technical support to internal or external clients via phone, email, and deskside interaction as needed.
• Communicate clearly with both technical and non-technical stakeholders, setting expectations and providing status updates on complex issues.
• Participate in a 24x7 support rotation, providing on-call coverage for critical infrastructure issues outside standard business hours.

Process & Governance

• Apply ITIL-aligned practices across incident, problem, and change management processes.
• Ensure changes to production systems follow established change management and approval procedures.

• Proven ability to resolve support tickets, maintain knowledge articles, and contribute to problem management through to full resolution.
• At least 5 years of experience supporting internal or external clients by phone, email, or deskside.
• Experience with PowerShell.
• ITIL knowledge or certification is an asset.
