D&G Solutions seeks a senior, hands-on IT Systems Administrator to establish internal ownership of our daily IT operations. As a federal services firm with approximately 200 employees, we are transitioning core IT responsibilities in-house from a managed service provider (MSP). In this senior individual contributor role, you will administer our Microsoft 365 environment, Azure resources, employee devices, and identity/access controls while supporting users directly and coordinating with specialized external security providers. You will play a foundational role in building practical procedures for reliable internal support, with a planned expansion to add a support and endpoint administrator in early 2027.
Roles and Responsibilities
- Administer Entra ID, Exchange Online, Teams, SharePoint, and Intune. Manage user access, multifactor authentication (MFA), conditional access policies, licensing, and device compliance policies.
- Establish and maintain Azure resources, role-based access permissions, managed identities, secrets, monitoring, and cost controls. Enable authorized internal developers to deploy and operate approved workloads independently.
- Resolve escalated and daily support tickets, provision and secure Windows laptops, coordinate hardware purchasing and shipping, track equipment inventory, and manage employee onboarding, offboarding, patching, and device replacements.
- Implement technical controls supporting applicable CMMC and NIST SP 800-171 requirements. Maintain compliance evidence, remediate vulnerabilities, test disaster recovery, and coordinate security alerts and incidents with external security providers.
- Manage access, single sign-on (SSO) integrations, licensing, and technical vendor coordination across business platforms (including Unanet, Paylocity, GovDash, Preveil, Jira, and ChatGPT for Business). Partner with internal application owners on integrations and support issues.
- Document system configurations and recovery procedures, automate repeatable administrative tasks, and train backup coverage. Maintain company-controlled administrative access and an accurate inventory of services and dependencies.
(Note: The intended steady-state workload is roughly 70% systems administration, security controls, and infrastructure improvement, and 30% user support and endpoint operations. Initial support duties will be broader while internal operations are being established. You will own routine technical execution within approved policies and budgets, while leadership retains spending and risk decisions.)
Required Qualifications
- 5+ years of hands-on systems administration or comparable experience, including direct ownership of a Microsoft 365 environment and Windows endpoints.
- Demonstrated administration of Entra ID, Intune, Exchange Online, Teams, and SharePoint, with the ability to personally diagnose and resolve complex access and device issues.
- Practical Azure administration experience covering resource deployment, role-based access control (RBAC), storage, managed identities, Key Vault, and monitoring, paired with the ability to learn new services quickly.
- Proven experience implementing technical security controls, investigating alerts, remediating findings, and maintaining audit-ready records of configurations and testing.
- Hands-on experience supporting employees directly and managing full device and account lifecycles, including secure offboarding and equipment recovery.
- Proficiency in automating recurring tasks using PowerShell (or comparable tools), maintaining clear technical documentation, and managing third-party vendors through issue resolution.
- Strong communication skills and sound judgment to explain technical tradeoffs, prioritize interruptions, operate independently within agreed authority, and escalate decisions requiring leadership approval.
Preferred Qualifications
- Experience in a federal contracting environment, including familiarity with Microsoft 365 GCC High and hands-on CMMC or NIST SP 800-171 implementation.
- Prior experience transitioning IT operations from an MSP or assuming ownership of an inherited environment.
- Familiarity with Windows Autopilot, infrastructure deployment templates, Azure container workloads, backup and recovery testing, and formal incident coordination.
- Experience administering Google Workspace.
- Familiarity with Cloud FinOps principles and cloud cost optimization.
