• Networking & Security: Administer routing/switching (VLANs, STP, LACP), IPv4/IPv6, site‑to‑site/IPSec and SSL VPNs; DNS/DHCP, NTP, and network services resilience. Configure next‑gen firewalls, IDS/IPS, web filtering, content security, and remote access; manage SD‑WAN where applicable. Implement network segmentation, zero‑trust principles, and QoS especially for VoIP and latency‑sensitive apps. Manage PKI/certificates: CSR generation, issuance, renewal automation, and certificate lifecycle across servers, load balancers, and apps.
• Windows Server, Active Directory & RDS: Support data integration and reporting tools to improve visibility across the supply chain. Ensure data accuracy and integrity in operational and customer‑facing applications.
• Collaboration: Microsoft 365 (SharePoint/OneDrive/Teams): Govern SharePoint/OneDrive permissions, sharing policies, sensitivity labels, and DLP/retention; support migrations and information architecture. Operate Teams/Teams Phone interop with existing PBX/SBCs where needed.
• Voice/Telephony (VoIP): Deploy and support VoIP solutions: SIP trunks, SBCs, dial plans, call routing, E911/999 configuration, QoS tagging and monitoring.
• Backup, DR & Security Operations: Own backup strategy (3-2-1/immutability) for on‑prem, cloud, and Microsoft 365; monitor job success and conduct restoration tests. Coordinate vulnerability management and remediation (OS, apps, cloud); collaborate with SOC/MDR where applicable. Maintain security incident runbooks, access reviews, and change control (CAB) with strong documentation.
• Service Delivery & Support: Act as L3 escalation for complex incidents/problems; drive root‑cause analysis and permanent fixes. Create high‑quality documentation, runbooks, and user‑facing knowledge base articles. Automate routine tasks using PowerShell (and/or Python); contribute to CI/CD/IaC where appropriate.
