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
