Operate the Network at Frontier Scale * Participate in on-call rotation and lead the response to high-severity network incidents. * Diagnose failures spanning GPUs, NICs, switches, cables, firmware, drivers, network operating systems, MRC, NCCL, Kubernetes, and training workloads. * Develop automated mitigation mechanisms, including path avoidance, node quarantine, workload relocation, and safe component remediation. * Create operational procedures for maintenance, upgrades, rollback, capacity expansion, and topology changes. Improve Large-Job Reliability and Performance * Work directly with training teams to investigate collective-performance degradation, stalls, timeouts, job restarts, and unexplained MFU loss. * Translate low-level network signals into clear job-level impact. * Establish network qualification gates for admitting nodes and racks into large training pools. * Run failure-injection and resilience testing to validate behavior under link, NIC, switch, and path failures. * Improve placement and routing policies for jobs spanning racks, rows, and network planes. Automate Fleet Operations * Build production-quality software and automation for network validation, monitoring, diagnosis, remediation, and fleet-wide change management. * Replace manual investigation with deterministic workflows and actionable alerts. * Automate firmware, driver, configuration, and network operating-system compliance checks. * Maintain authoritative network inventory, topology, and configuration state. * Reduce mean time to detect, isolate, mitigate, and permanently resolve failures. Drive Cross-Company Execution * Lead technical investigations involving internal infrastructure teams, cloud and datacenter operators, Azure Networking, NVIDIA, switch and NIC teams, and network-software partners. * Own incidents through resolution, even when the underlying failure crosses organizational boundaries. * Produce clear root-cause analyses with corrective actions, owners, and completion dates. * Convert recurring production failures into requirements for future network, server, and accelerator architectures. * Create runbooks and train engineers across regions to provide reliable round-the-clock coverage.
