Cloud & Network Infrastructure Architect

Role Summary Designs, implements, and optimizes highly available, secure, multi-cloud network infrastructure spanning AWS and Azure, with hybrid connectivity into on-premises County data centers. Owns the architecture, resiliency design, and traffic engineering for enterprise-scale cloud networking — this is infrastructure-architecture work, not application development. Core Responsibilities Design and manage network infrastructure across AWS and Azure environments, including multi-region and multi-Availability Zone deployments Architect highly available, fault-tolerant network designs with resiliency patterns and automated failover Implement hybrid cloud connectivity using AWS Transit Gateway and Azure ExpressRoute Provision and manage Megaport Virtual Cross Connects (VXCs) for private cloud-to-on-prem connectivity Manage traffic engineering: ingress/egress routing, path optimization, high-availability network design Deploy and manage cloud-native and F5-based load balancing (AWS ELB, Azure Load Balancer/App Gateway, F5 LTM/GTM) Deploy and manage virtual firewalls and NVAs (Palo Alto VM-Series, Cisco CSR 8000v) alongside native cloud security controls Design VPC/VNet peering, hybrid connectivity, and multi-cloud architectures Configure and manage BGP across cloud, hybrid, and multi-cloud environments Apply cloud network security principles: Security Groups, NSGs, NACLs, segmentation, compliance alignment Requirements Skills Required AWS and Azure networking services (Transit Gateway, ExpressRoute, VPC/VNet) Megaport services and VXC provisioning F5 VIPRION LTM/GTM or equivalent cloud-native load balancing Network Virtual Appliances: Palo Alto VM-Series, Cisco CSR 8000v BGP configuration in hybrid/multi-cloud environments Cloud security constructs (Security Groups, NSGs, NACLs) Storage architecture across multi-vendor and multi-cloud platforms (Dell PowerMax, NetApp, Pure Storage — for storage-architect variants) Experience Required 6+ years designing, implementing, and managing cloud-based network infrastructure (AWS and Azure) 4+ years designing highly available/resilient cloud network architectures, including DR and failover 4+ years hands-on with AWS/Azure networking services: Transit Gateway, ExpressRoute, load balancing, hybrid connectivity 4+ years with Megaport services (VXC provisioning, hybrid/multi-cloud networking) 4+ years in traffic engineering, network segmentation, and firewall deployment (native + NVA) Education / Training Bachelor's degree in an IT-related or Engineering field (or equivalent experience, year-for-year) At least one of: AWS Certified Advanced Networking – Specialty, AWS Certified Solutions Architect, Microsoft Certified: Azure Network Engineer Associate
