Rather than owning a single environment, you'll work across a portfolio of client networks and tenants — keeping their Active Directory, identity, and PKI infrastructure healthy and secure, and their Microsoft 365 platforms running reliably. This is a hands-on, client-facing engineering role for someone who is equally comfortable troubleshooting a DNS issue for one client, issuing a certificate through AD CS for another, and helping a client's end users get the most out of Word, Outlook, Excel, and Teams — all while managing multiple tickets and projects against defined SLAs. Key Responsibilities Administer and support Active Directory Domain Services across multiple client environments, including domain controllers, OU structure, Group Policy, and directory replication. Manage core network services — DNS, DHCP, and NTP — for client environments, ensuring reliable name resolution, IP address allocation, and time synchronization. Design, deploy, and maintain Active Directory Certificate Services (AD CS) and PKI for clients, including certificate templates, issuance, renewal, and revocation. Administer client Microsoft 365 tenants, including Entra ID (Azure AD) identity, conditional access, licensing, and device/app management. Support and maintain Exchange Online, SharePoint Online, and Microsoft Teams for clients, including configuration, permissions, and troubleshooting. Provide advanced end-user support for Windows and Microsoft 365 desktop applications — including Word, Outlook, and Excel — across the client base. Serve as an escalation resource for Tier 2/3 tickets involving identity, directory services, network services, or M365 availability, performing root-cause analysis and remediation. Participate in client onboarding and project work, including new AD and M365 tenant builds, migrations, and infrastructure deployments as part of VAR-sold solutions. Document all work clearly and consistently in the company's PSA/ticketing platform and manage competing priorities across multiple clients against contracted SLAs. Maintain accurate client documentation for AD, PKI, and M365 configurations, and contribute to change management and security best practices. Collaborate with the sales and account management teams on identity governance, certificate lifecycle management, and technology recommendations for clients.
