Deploy, operate and maintain RDMA-based network architectures (RoCE/InfiniBand) for cluster with thousands of nodes
Optimize network performance for distributed collective communication workloads (NCCL, MPI, etc.)
Solve complex network issues in distributed collective communication (e.g., NCCL/MPI communication bottlenecks)
Use automation tools for network provisioning, monitoring, diagnostics, and network performance profiling (latency/throughput analysis)
Implement CI/CD pipelines for network infrastructure-as-code
Manage end-to-end network lifecycle: deployment, configuration, monitoring, upgrades
Collaborate with computing algorithm engineers to troubleshoot network-related bottlenecks in training/inference pipelines
Bridge Computing framework requirements with underlying network infrastructure capabilities
Ensure compliance with security and scalability requirements
Qualifications
Strong scripting skills (Python/Go/Bash) for operational automation
Expert-level RDMA operational experience (RoCEv2/InfiniBand)
Understanding of Linux internals (kernel bypass, syscall optimization, etc), and proficient in Linux network stack tuning (irqbalance, NUMA, hugepages)
Hands-on experience with RDMA/DPDK performance tuning
Strong knowledge of network protocols (TCP/IP, RoCEv2) and NIC architecture principles
Ability to abstract complex technical concepts into architectural diagrams
Proven track record of translating R&D innovations into production solutions
Strong communication skills for cross-functional collaboration with Computing researchers and SRE teams
Experience managing production computing networks
Familiar with Kubernetes networking (CNI, Multus, SR-IOV) and GPU-aware scheduling
Background in computing system optimization (NVIDIA collective libraries, MPI tuning)
Deep understanding of computing workload patterns and their network implications
