Maintain hybrid connectivity (SD‑WAN overlays, ExpressRoute/VPN, site‑to‑cloud tunnels).
Support Azure‑integrated networking (VNETs, routing, hub/spoke, private endpoints, Azure Firewall/NVA, Bastion, WAF) and identity flows aligned to Entra ID.
Enforce Purdue‑aligned segmentation/DMZ patterns for IT/OT.
Monitor and maintain network health via Azure Monitor and partner tools; manage patching, configuration standards, backups, and resilience.
Maintain onsite installation, cabling, documentation, and server‑room hygiene (cabinets, UPS, racks); support lifecycle management for switches, firewalls, wireless, and related equipment.
Enable secure IT/OT connectivity and vendor access (ZTNA/VDI/Secure Remote Access) and collaborate with MSPs, SOC/NOC, and global architects on cutovers, migrations, audits, and incident escalation.
What You Bring
Required:
Experience: 5+ years in networking, infrastructure, or mixed IT/OT environments.
Hands‑on expertise with FortiGate firewalls and SD‑WAN.
Strong Cisco switching/routing, VLANs, L2/L3, enterprise wireless/Meraki.

Azure networking & identity fundamentals (VNETs, routing, private endpoints, Entra ID, MFA/CA); Windows Server core services (AD/DNS/DHCP).
Clear communication with technical and non‑technical users, and the ability to collaborate with global teams/MSPs while balancing project work with urgent onsite incidents.
Preferred:
