Super‑charge the network stack. Tune TCP/IP, RDMA (primarily RoCE congestion control), kernel‑by‑pass frameworks (DPDK, XDP, eBPF) and NIC offloads to squeeze microseconds off packet latency for AI & HPC workloads. Deploy & optimize at scale. Roll out new ToR/spine switches (from NVIDIA, Arista, Juniper, and others), validate SmartNIC and BlueField networking, configure BGP/EVPN fabrics, and optimize flow control (PFC, ECN) for zero‑loss transport. Automate observability. Build NIC‑to‑orchestrator telemetry pipelines, packet‑loss detection bots, and real‑time throughput/latency dashboards. Root‑cause the gnarly stuff. Lead packet captures, congestion analyses and latency regressions; turn insights into switch firmware patches, kernel tuning and topology optimizations. Drive vendor collaboration. Pair with networking vendors to debug hardware, accelerate RDMA paths, validate optics, and integrate emerging network hardware (800G/1.6T, LPO/CPO) Continuously improve. Inject link failures, run game‑days simulating network partitions and codify post‑mortem learnings into SLIs/SLOs that matter to customers.
