• Manage hybrid Microsoft 365 and Active Directory services (Exchange Online, Teams, SharePoint permissions, Azure AD).
• Maintain Windows servers, patching, backups, disaster recovery procedures, and monitoring systems.
• Configure, maintain, and troubleshoot enterprise network components: switches, routers, firewalls (e.g., Fortinet, Cisco, Palo Alto), VPN, WLAN.
• Implement and manage security tools: endpoint protection, MFA, email security, vulnerability management, and security monitoring.
• Participate in incident response, root‑cause analysis, and remediation efforts.
• Serve as Tier 3 technical escalation for complex issues across systems, networking, and security.
• Maintain endpoint environment (Windows laptops/desktops, SaaS applications, patching, compliance).
• Oversee user lifecycle workflows and ensure provisioning standards across AD and Microsoft 365.
• Lead implementation of IT infrastructure projects including migrations, upgrades, and new technology rollouts.
• Document systems, create runbooks, and improve operational processes and automation.
