The Main Responsibilities

• Own the architecture and evolution of resilient, scalable Internet, MPLS core, VPN edge, and Metro Ethernet networks.
• Develop architecture standards and roadmaps for routing, switching, MPLS, multicast, carrier Ethernet, merchant-silicon platforms, optics, and high-speed interfaces.
• Design and govern network automation using model-driven interfaces, open APIs, infrastructure as code, reusable service models, automated testing.
• Design and develop streaming telemetry and observability solutions for network health, performance, capacity, service-level assurance, and compliance.
• Design and develop event-driven and closed-loop workflows for provisioning, validation, anomaly response, and remediation.
• Evaluate and apply AI-enabled capabilities for anomaly detection, predictive analytics, capacity forecasting, incident correlation, root-cause analysis, and guided operations.
• Lead proof-of-concepts, technical and economic evaluations, platform selection, and cross-functional architecture decisions.
• Provide technical leadership across IP, Optical/Transport, operations, security, data, and software engineering teams.
