Identity & Access Management

Administer Active Directory (users, groups, GPOs, OUs)
Execute access change requests and decommissioning activities
Support Microsoft Entra ID user, role, and Conditional Access administration
Maintain identity hygiene and lifecycle processes

Microsoft 365 Administration

Administer Microsoft 365 tenant services
Manage licensing and configuration settings
Support Exchange Online and hybrid environments

Execute litigation hold and retention administration (administrative tasks only)

Endpoint Management & Security Operations

Support endpoint patching and vulnerability remediation at scale
Enforce CIS and approved security baselines
Execute endpoint policy enforcement and failure remediation
Support compliance and remediation reporting

Incident, Request & Change Execution

Respond to and resolve incidents across servers, endpoints, and Microsoft 365 (P1–P4)
Participate in a 24×7 on‑call rotation for Priority 1 incidents
Execute approved changes in accordance with CAB and ITIL processes
Coordinate escalations with vendors and internal specialist teams
Contribute to root cause analysis and continuous service improvement

How This Role Operates

Dedicated to a single enterprise client during business hours (staggered shifts)
Works within a governed MSP framework (SDM, SLAs, CAB)
Uses automation and tooling for repeatable operational tasks
Supported by shared NOC, cloud, escalation, and specialist teams
