Lead Microsoft Platform Administrator

Systems Engineering Solutions Corporation · Alexandria, United States (Hybrid) · Full-time · Posted 2026-11-13

Workplace: hybrid

Description

Years of Experience: 15 years of experience, or 12 years with a Master’s degree

Education Requirements:Bachelor’s degree in computer science, Information Systems, Engineering, or related field

Program Description: The program provides end to end IT Infrastructure support services, including Tier 1 Help Desk, Tier 2 End User Support, Tier 3 Server, Platform, and Network Infrastructure Support and Engineering with responsibility for incident resolution, service requests, monitoring, lifecycle support, and escalation management.

Position Description: The Lead Microsoft Platform Administrator is the team lead for the platform team. The role is responsible for the administration, operation, and continuous improvement of the agency’s Microsoft Azure platform, Microsoft 365 and Exchange services, and on-premises and cloud-hosted Windows and Linux servers. This is a working lead role: the administrator performs hands-on Tier 3 engineering and also executes, delegates, tracks, and manages the team’s incidents, recurring operations and maintenance (O&M), and projects, including Azure DevOps (ADO) backlog management, sprint planning, and status reporting. The role works closely with architecture, cybersecurity, networking, and engineering teams to keep services aligned with enterprise standards.

Work Model: The platform team concurrently handles Tier 3 incidents, recurring O&M, and projects, and priorities may change daily. The lead sets the team’s priorities, reassigns work when urgent incidents arise, communicates resulting schedule impacts, and makes sure planned work resumes without losing ownership of existing commitments. Planned work such as maintenance and change windows may at times require shifting the schedule to work after hours, and the lead is called when a major issue occurs outside business hours.

Requirements

·       Review team members’ change requests, ticket documentation, and runbooks before submission or closure.

·       Plan coverage for leave and after-hours change windows so that each platform function has a trained backup.

·       Mentor and develop team members, including cross-training to reduce single points of knowledge.

·       Serve as the team’s escalation point for technical decisions and priority conflicts.

Azure Platform Engineering and Administration

·       Lead and support administration of Azure environments, including subscriptions, resource groups, landing zones, governance and tagging, virtual machines, storage accounts, and platform services.

·       Monitor platform health using Azure Monitor, Log Analytics, Application Insights, and Microsoft Defender.

·       Maintain backup, disaster recovery, and high availability using Azure Backup and Azure Site Recovery.

Identity, Microsoft 365, and Exchange

·       Lead and support administration of Microsoft 365 services and Exchange (Online and on-premises).

Tier 3 Incident Support

·       Own the team’s Tier 3 incidents from assignment to closure, whether worked directly or assigned to a team member.

·       Lead troubleshooting of complex and cross-team Azure, identity, Microsoft 365, Exchange, and server issues.

·       Escalate to Microsoft or other vendors with a complete case record, and identify recurring incidents for permanent fixes through problem management.

·       Participate in and manage the team’s on-call rotation.

Operations and Change Management

·       Make sure the team’s recurring O&M tasks are completed on schedule and recorded in ServiceNow.

·       Follow the NCUA change management process and hold the team to it.

Projects

·       Lead platform projects from planning through closeout, including scope, milestones and dependencies, stakeholder agreement, phased implementation, and user communications.

·       Support cloud migration projects for servers, applications, databases, and hybrid workloads.

Communication and Documentation

·       Communicate directly with end users, government stakeholders, and contract counterparts: explain issues and impact in plain language, set expectations on timelines, and confirm outcomes.

·       Make sure ticket notes and work logs are written in ServiceNow as work happens, so another engineer can pick up the issue without re-contacting the user.

·       Maintain platform documentation, including runbooks, SOPs, knowledge articles, and architecture diagrams, and update it after incidents, changes, and projects.
