Your Impact

As a key contributor to Cisco’s AI/ML infrastructure initiatives, you will plan, execute, and analyze comprehensive benchmarks on Cisco switches, focusing on throughput, latency, congestion, incast, failover, path diversity, and workload performance to ensure optimal AI/ML network operations.

You will be guiding AI/ML workload deployments from initial scoping and test planning through execution and benchmark analysis, ensuring success criteria are met. Your role includes developing AI-driven automation workflows to streamline network development, operations, and implementations.

You will define rigorous benchmark methodologies, test plans, KPIs, pass/fail criteria, and reporting structures for AI RoCE Ethernet fabrics, benchmarking fabric performance across critical metrics including latency, throughput, path diversity, ECMP and link utilization, congestion behavior, packet drops, retransmissions, queue occupancy, and recovery behavior. You will run and analyze performance tests using industry-standard tools such as NCCL, RCCL, ib_write_bw, ib_read_bw, ib_send_bw, ib_write_lat, netperf, iperf, MPI, OSU benchmarks, and microburst test methods.

You will validate switch ASIC features including buffers, schedulers, QoS/queuing, ECMP behavior, telemetry, hashing, traffic distribution, and congestion visibility.

Owning switch OS configuration and automation, you will utilize SONiC, NX-OS, Ansible, Python, Bash, Git, and related tooling to implement and validate advanced features such as SRv6, segment routing, uSID, Adj-SID, and policy-based pathing as required. You will document PoC architecture, benchmark methodologies, topology diagrams, configurations, results, findings, and recommendations.

This role empowers you to shape the future of AI infrastructure networking by delivering scalable, high-performance, and resilient network fabrics that meet the stringent demands of AI/ML workloads, driving innovation and customer success at Cisco.
