## Description

Within Nscale, the Network Operations team is responsible for the performance and reliability of the high-speed networks that underpin our AI platforms. These front-end networks are critical to inference workloads, cluster management, data movement, and storage connectivity., In this role, you will be responsible for the day-to-day health, stability, and performance of Nscale's large-scale Ethernet front-end networks. You'll bring deep operational expertise from hyperscale or high-performance environments and play a key role in incident response, performance tuning, automation, and continuous improvement of production AI networking systems., * Owning the operational health, configuration consistency, and performance tuning of large-scale Ethernet front-end fabrics (leaf-spine / Clos) supporting AI inference, management, and storage workloads

 * Leading the diagnosis and resolution of complex network incidents (P0/P1), spanning optics, routing, switching hardware, long-haul circuits, and storage connectivity layers
 * Driving blameless postmortems and implementing preventative fixes to improve long-term fabric stability and availability
 * Partnering with SREs to define requirements for automation and tooling, and contributing to network provisioning, validation, and monitoring systems
 * Collaborating with Network Architecture and Engineering teams to validate designs and enforce standards for routing, congestion management, firmware baselines, and change safety
 * Monitoring fabric utilisation and performance, identifying bottlenecks, and tuning for predictable latency and throughput on front-end networks
 * Acting as a subject matter expert for cross-functional teams on high-speed Ethernet networking, long-haul/DCI circuits, and storage network integration
 * Participating in an on-call rotation supporting mission-critical, customer-facing infrastructure
