Sr Lead Site Reliability Engineer - Network

Operate Lumen's Network as a Service (NaaS) implementation in partnership with traditional operations teams and development counterparts. Provide technical direction and resolution of systemic issues related to Lumen's Network as a Service (NaaS) implementation across a broad range of network topologies and applications. Plan, design, and implement scalable local and wide-area network solutions between multiple platforms and protocols. Responsible for system performance, supporting/troubleshooting issues, and coordinating across multiple organizations and teams. Develop tools and utilities to automate deployment, administration, investigation, and monitoring.

This will require a strong understanding of Lumen's Layer 1, Layer 2, & Layer 3 networks and products, a strong understanding of Lumen's Edge Compute implementation, and a strong understanding of software development methodologies. This role will work across the network architecture, engineering, and systems development organizations and teams to ensure alignment to production readiness and operationalization guidance.

This role is designated as a fully remote position within the United States.

• Subject Matter Expert for network automation platform applications, services, and hosting environments. Focused on core components, supports directly with expertise and escalates to responsible team but remains engaged and learns
