Knight Federal Solutions supports Department of Defense and Intelligence Community programs in simulation and training, IT, intelligence and engineering. Our IT environment is a Microsoft 365 GCC tenant, Azure, and an on-premises enclave in Orlando, all operated to CMMC Level 2 and NIST SP 800-171 requirements for Controlled Unclassified Information.

We are hiring a Systems Administrator to own day-to-day IT operations and support for about 170 staff, and to grow, over a planned 18 to 24 months, into the engineer who co-owns our security and compliance environment and serves as alternate Information System Security Manager. You will start by taking the service queue and the onboarding pipeline; you will finish the second year able to run the environment and stand in front of a CMMC assessor.

This is a hands-on role on a two-person team. You will see every layer of the stack, from end-user devices to Azure networking to Sentinel, and you will help build the automation and AI agents that remove repetitive work rather than live with it.

Operations and Support

• Own Tier 1 and Tier 2 support in Jira Service Management: triage, resolve, document and close, with same-business-day first response as the standard.
• Run employee onboarding and offboarding end to end: accounts, licences, groups, devices, MFA enrolment and access removal, coordinated with HR and the FSO.
• Administer Microsoft 365 GCC: Exchange Online, SharePoint and Teams, Entra ID (users, groups, Conditional Access operations), Intune (Windows and mobile), Defender for Endpoint.
• Perform first-line triage of security alerts from Defender and Sentinel, following runbooks and escalating what matters.
• Patch and maintain Windows Server, domain controllers, Hyper-V hosts and the backup platform; verify backups and restores on schedule.
• Manage endpoint lifecycle: imaging, Autopilot, hardware inventory, repairs and vendor RMAs.
• Support the on-premises enclave: firewall rule requests, switch ports, Wi-Fi, VPN client issues, printers and MFPs, MFA (Duo) enrolment and troubleshooting.
• Maintain documentation and collect compliance evidence as part of normal work, not as a separate project.
• Automate repetitive tasks with PowerShell and, as you learn the platform, with our n8n agent workflows.

Systems, Security and Compliance Ownership

• Become named owner for Intune, Defender and vulnerability management, backup, Jira Service Management and the enclave hardware.
• Operate Microsoft Sentinel: analytics rules, incident handling, log-source health and monthly reporting.
• Maintain the System Security Plan and control evidence for your areas; participate in and then lead assessor evidence sessions.
• Act as alternate ISSM: change control, access reviews, incident response coordination, POA&M tracking.
• Back up the IT Manager on vendor and licensing relationships (Microsoft CSP, managed security services, telecom) and on Azure and AWS GovCloud operations.
• Mentor department champions on the shared agent platform and own the agents that run its own work.

Required

• 3 to 5 years administering Windows environments in a business setting, including Microsoft 365 and Entra ID (Azure AD).
• Hands-on experience with Intune or an equivalent MDM, Windows Server and Active Directory, and a ticketing system.
• Working knowledge of networking fundamentals: IP addressing, DNS, DHCP, VLANs, VPN, firewall rule logic.
• PowerShell for administration: you can write and read scripts, not only run them.
• Clear written communication: tickets, runbooks and change records that someone else can follow.
• U.S. citizenship and eligibility for a DoD security clearance.
• Ability to lift and rack equipment up to 40 pounds and work occasionally outside business hours for maintenance windows.

Preferred

• Experience in a Microsoft 365 GCC or GCC High tenant, or in another regulated environment (DoD, federal, healthcare, finance).
• Familiarity with CMMC, NIST SP 800-171 or a comparable control framework, and with collecting audit evidence.
• Azure fundamentals: virtual networks, VPN gateways, virtual machines, Log Analytics; any AWS exposure is a plus.
• Microsoft Defender for Endpoint, Microsoft Sentinel or another SIEM/EDR pair.
• Hyper-V, Veeam or similar backup, Cisco switching and wireless, WatchGuard or comparable firewalls, Duo or another MFA platform.
• Jira Service Management administration; exposure to n8n, Power Automate or similar workflow tools.
• One or more of: AZ-104, SC-200, AZ-500, MS-102, CompTIA Security+ (Security+ or equivalent will be required within 12 months for the alternate ISSM designation).
