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
