About the job
Join our team as a Principal Cloud Network Architect to lead a transformative network and infrastructure consolidation initiative following the acquisition of multiple telecommunications and UCaaS companies. Our current cloud environment is complex and dispersed, encompassing over 40 AWS accounts, isolated VPC architectures, and various legacy on-premises data centers.
This is a 6-8 month design engagement where you will be pivotal in establishing a definitive target-state hybrid cloud routing fabric. Your role will involve utilizing AWS Cloud WAN and Transit Gateway in conjunction with Digital Realty's interconnect capabilities while delivering production-ready blueprints to our core engineering team. You will work in close collaboration with the Lead Network Convergence Architect to ensure seamless integration of cloud edge routing with our global MPLS/BGP/SD-WAN core.
Key Responsibilities:
- Architect the global cloud transit backbone by assessing 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 over 40 AWS accounts.
- Design the hybrid interconnect fabric spanning physical and cloud environments, ensuring Layer 2/Layer 3 connectivity between legacy data centers and AWS using Digital Realty (PlatformDIGITAL / ServiceFabric) and AWS Direct Connect.
- Establish a cloud-native security perimeter and identity access management by engineering AWS WAF, AWS Shield Advanced, and centralized logging, while transitioning raw credential management to AWS KMS/Secrets Manager and integrating AWS IAM with Entra ID for SSO.
- Standardize cloud routing boundaries for e-commerce and voice workloads, specifically by architecting a split-routing model: securely directing SIP signaling through AWS while maintaining real-time RTP media on physical hardware to mitigate cloud latency and
