• Architect and implement enterprise-scale cloud and HCI architectures, ensuring seamless connectivity between on-prem infrastructure (HyperFlex, VxRail) and Microsoft Azure via ExpressRoute, VPN Gateways, and Virtual WAN. • Serve as a strategic advisor to infrastructure, application, and security teams, aligning networking choices (latency, bandwidth, and topology) to business performance goals. • Define and maintain architectural blueprints for hybrid networking, including IP addressing schemes, routing protocols (BGP), and VNet/VPC peering standards. • Architect Active Directory and Azure AD for secure identity, while implementing Network Security Groups (NSGs), ASGs, and Azure Firewall to enforce micro-segmentation. • Lead migration efforts, transitioning legacy workloads to Azure, ensuring network integrity and minimal downtime during "lift and shift" or refactoring projects. • Evaluate and deploy HCI platforms, optimizing the underlying networking fabric (Cisco ACI or Dell SmartFabric) for maximum compute and storage throughput. • Implement disaster recovery strategies leveraging Azure Site Recovery and global load balancing (Traffic Manager, Front Door) to ensure high availability. • Collaborate with security teams to harden network entry points and enforce compliance (NIST, ISO 27001) through deep packet inspection and encrypted transit. • Lead cross-team design sessions and PoCs for emerging network technologies like Zero Trust Network Access (ZTNA) and SASE.
