Job DescriptionWe are looking for a Principal Cloud Network Architect to support a large-scale network and infrastructure consolidation program following the acquisition of 5+ telecommunications and UCaaS companies. The current cloud environment is highly fragmented, spanning 40+ AWS accounts, isolated VPC architectures, and multiple legacy on-premises data centers.This is a 6-8 month design engagement focused on defining the definitive target-state hybrid cloud routing fabric. The scope includes leveraging AWS Cloud WAN and Transit Gateway alongside Digital Realty interconnect capabilities and delivering production-ready blueprints to the core engineering organization. The role operates in close collaboration with the Lead Network Convergence Architect, ensuring seamless integration between cloud edge routing and the global MPLS/BGP/SD-WAN core.Responsibilities:Architect the global cloud transit backbone by evaluating and defining the target-state AWS multi-account routing model, including a final design decision between AWS Cloud WAN and regional Transit Gateway (TGW) architectures to unify 40+ AWS accounts.Design the hybrid interconnect fabric across physical and cloud environments, including Layer 2/Layer 3 connectivity between legacy data centers and AWS using Digital Realty (PlatformDIGITAL / ServiceFabric) and AWS Direct Connect.Define the cloud-native security perimeter and identity access by engineering AWS WAF, AWS Shield Advanced, and centralized logging, while replacing raw credential management with AWS KMS/Secrets Manager and integrating AWS IAM with Entra ID for SSO.Standardize cloud routing boundaries for e-commerce and voice workloads, specifically architecting a split-routing model: securely steering SIP signaling through AWS while strictly keeping real-time RTP media on physical hardware to eliminate cloud latency and "noisy neighbor" impacts.Deliver a transition blueprint including Infrastructure-as-Code (IaC) migration templates and phased rollout strategy to enable migration from the current fragmented state to a unified cloud fabric without disruption to voice or e-commerce services.Drive strategic Cloud FinOps and architecture economics by auditing existing AWS spend, executing compute right-sizing, and implementing Reserved Instances and Savings Plans alongside structural cloud changes.
