Senior IT Systems Administrator

• 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.)
