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.
