The Role
Join Lumen as a Senior Lead Network Architect and help transform our large-scale network infrastructure. You will design resilient, scalable architectures across Internet and MPLS core networks, VPN edge services, and Metro Ethernet technologies. You will also advance network automation, streaming telemetry, closed-loop assurance, and AI-enabled operations to improve service reliability, performance, security, and operational efficiency.
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.
