• At least 5 years of hands-on experience with Palo Alto Networks firewalls (PAN-OS), including Panorama management.
• Strong practical knowledge of GlobalProtect architecture (portal/gateway design, IP pools, split tunneling, redistribution).
• Solid knowledge of dynamic routing protocols, particularly BGP (route redistribution, filtering, multi-homed peering); OSPF is a plus.
• Proven experience with Microsoft Azure networking: VNets, ExpressRoute, VPN Gateway, NSGs, Route Tables, Azure Firewall/Front Door (as applicable).
• Experience designing and maintaining multi-region WAN/VPN architectures that connect offices across multiple continents.
