Lead HPC Network Engineer (General Rodríguez)

We are looking for a Lead HPC Network Engineer to drive the strategy, architecture, and engineering excellence behind advanced AI, research, and Kubernetes-based GPU infrastructure for a major general technology client.

The role focuses on defining the technical vision, leading architecture decisions, and setting engineering standards for high-performance network fabrics supporting large-scale LLM and distributed AI workloads, including InfiniBand/RDMA, high-speed Ethernet, Kubernetes networking, host‑side GPU networking, SmartNIC/DPU technologies, and deep network observability. As a technical leader, you will mentor senior engineers, influence client roadmaps, and own end‑to‑end delivery of mission‑critical network platforms.

The ideal candidate combines deep expertise across InfiniBand NDR/HDR and next‑generation fabrics, RDMA/RoCE, NVIDIA/Mellanox networking, NCCL/MSCCL communication patterns, Linux host networking, PCIe/GPU/NIC topology, and Kubernetes networking for GPU clusters, with a proven track record of leading engineering teams and shaping large‑scale HPC/AI network platforms.

Responsibilities
- Own the architectural vision and long‑term roadmap for high‑performance InfiniBand/RDMA and Ethernet fabrics supporting large‑scale GPU clusters and distributed AI/LLM workloads
- Lead the design, evaluation, and selection of cluster network topologies, including Fat‑tree, Clos, Rail‑optimized, and Dragonfly, and define decision frameworks aligned with workload scale, performance, and cost constraints
- Establish engineering standards and best practices for host‑side networking, including NIC configuration, drivers, firmware, IRQ affinity, NUMA placement, PCIe topology, and GPU‑to‑NIC communication paths
- Drive performance engineering initiatives for RDMA/RoCE, NCCL/MSCCL, and collective communication across multi‑node GPU training workloads, and lead complex root‑cause investigations
- Define the reference architecture for Kubernetes networking on GPU cluste Postúlate en Kit Empleo: kitempleo.com.ar/empleo/pm3xc
