## Description

We are seeking an experienced Senior Network Engineer to own day-to-day operations of the data center network and to drive refresh and infrastructure improvements. This role requires hands-on operational work, hardware migration/refresh planning, and configuration management, with an SRE mindset focused on standardization, visibility, stability, reliability, and availability.
What You'll Do

 * Lead the planning and execution of large-scale network refresh programs for switches and routers approaching or at End-of-Support, including hardware staging, configuration migration, and phased cutovers with minimal production impact
 * Develop, maintain, and implement detailed Method of Procedure (MOP) documents, migration runbooks, and rollback plans for all planned changes and refresh activities
 * Operate and maintain production data center network infrastructure across newly built and expanding clusters, ensuring high availability, reliability, and performance
 * Investigate and resolve complex production network issues, from hardware and physical-layer faults to routing, overlay, and tooling, including RCA and follow-through fixes
 * Identify opportunities to optimize the data center network and how it is operated, develop proposals, and implement approved changes
 * Standardize the data center network environment - designs, configurations, operating procedures, and tooling - so clusters are consistent and easier to operate at scale
 * Drive network visibility by defining and maintaining metrics, dashboards (e.g., Grafana), and alerts that improve availability and stability, including network health, refresh progress, and post-migration validation
 * Coordinate with vendors for TAC support escalations, RMA processing, firmware guidance, and support contract management
 * Create and maintain comprehensive network documentation, datacenter cutsheets, topology diagrams, IP address management (IPAM) records, and operational runbooks
 * Travel up to 10% as required to support datacenter projects and operations
