Meet the Team 

You will join Cisco's AI infrastructure networking team, focused on validating high-performance Ethernet fabrics for AI/ML workloads and helping customers and partners deploy scalable, resilient data center networks.

Your Impact 

In this role, you will plan and run AI/ML infrastructure benchmarks, validate fabric designs, and translate results into reference architectures, deployment guidance, and customer-ready recommendations. The work connects lab validation with real customer outcomes across switching, host networking, RoCE fabrics, automation, and telemetry.

• Plan, execute, and analyze AI/ML network benchmarks covering throughput, latency, congestion, incast, failover, path diversity, and workload performance.

• Design, implement, and validate L3 leaf-spine fabrics for AI infrastructure using eBGP/iBGP, BGP unnumbered, EVPN/VXLAN, VRFs, ECMP, multi-tenancy, and SRv6.

• Define benchmark methodology, KPIs, pass/fail criteria, repeatability requirements, and reporting for AI Ethernet/RoCE fabrics.

• Run performance tests with NCCL, RCCL, ib_write_bw, ib_read_bw, ib_send_bw, ib_write_lat, netperf, iperf, MPI, OSU benchmarks, and microburst methods.

• Create validated designs, reference architectures, configuration templates, runbooks, benchmark reports, and deployment recommendations for customers and engineering stakeholders.

Minimum Qualifications

• 4-6 years of hands-on experience in infrastructure benchmarking, network validation, data center networking, AI/cloud infrastructure, network implementation, or systems performance engineering.

• Hands-on experience designing, configuring, and troubleshooting L3 leaf-spine fabrics.

• Strong understanding of Ethernet/IP networking, including L2/L3 forwarding, BGP, ECMP, EVPN/VXLAN, VRFs, ACLs, QoS, MTU, telemetry, and troubleshooting.

• Working knowledge of RDMA, RoCEv2, PFC, ECN, congestion control, QoS queues, buffer behavior, and lossless Ethernet concepts.

• Hands-on Linux and automation experience using Python, Ansible, Bash, Git, and CI/CD pipelines.

Preferred Qualifications

• Experience with SONiC, NX-OS, switch OS configuration, and network automation workflows.

• Experience validating switch ASIC behavior, including buffers, schedulers, QoS/queuing, ECMP hashing, traffic distribution, telemetry, and congestion visibility.

• Familiarity with SRv6, segment routing, uSID, Adj-SID, and policy-based pathing.

• Experience developing AI-assisted automation workflows using tools such as Copilot, Claude, Cursor, or Codex.

• Clear written and verbal communication skills, including experience presenting benchmark results, validated designs, and technical recommendations to customers, executives, product teams, and engineering stakeholders.
