About the role

Key responsibilities & impact

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.

Requirements

What you’ll need

8+ years in IT infrastructure/architecture, with 5+ years of focus on AWS-native networking, multi-account transit architectures, and hybrid cloud convergence.
Advanced AWS networking expertise, including AWS Cloud WAN, Transit Gateway, Direct Connect, VPC Lattice, Route 53, and cross-account governance (IAM / Resource Access Manager).
Strong "Hybrid BGP Fluency" (AS-PATH, MED, Local Pref) to act as the cloud-side counterpart to core network engineers, seamlessly accepting route handoffs at AWS Direct Connect or Microsoft Meet-Me Room edges without creating routing loops.
Deep expertise in AWS-native security perimeters (AWS WAF, Shield Advanced, GuardDuty, Security Hub) and enterprise identity federation.
Proven track record designing cross-region AWS Disaster Recovery (DR) architectures and executing Cloud FinOps cost-optimization strategies.
In-depth knowledge of Infrastructure as Code using Terraform and AWS CloudFormation for large-scale network and routing automation.
Experience in M&A cloud consolidation, including unifying fragmented or “shadow IT” AWS environments into enterprise-grade governance models.
