Essential Skills

High-Performance Networking:

- InfiniBand Mastery: Deep operational knowledge of NVIDIA Quantum InfiniBand switches, cable types (NDR/HDR), and troubleshooting commands.
- AI Ethernet (RoCEv2): Solid understanding of RDMA over Converged Ethernet (RoCEv2), including the configuration of PFC and ECN on switches (Spectrum/Arista/Cisco/Juniper).
- Fabric Management: Experience with NVIDIA UFM (Unified Fabric Manager) for managing large-scale fabrics.

Automation & Tools:

- NetDevOps: Proficiency in Ansible for network automation (e.g., ansible-networking collections).
- Linux Networking: Comfortable navigating Linux CLI to troubleshoot host-side networking (ip link, tcpdump, sysctl tuning).
- Protocol Knowledge: Practical implementation skills in BGP, EVPN, and VXLAN for multi-tenant AI clouds.

Desirable Experience

- Cisco AI Integration: Experience with Cisco Nexus Dashboard or Cisco 8000 series in an AI context.
- DPU Configuration: Experience configuring NVIDIA BlueField DPUs and working with the DOCA framework.




- Optical Networking: Ability to interpret transceiver signal levels (DOM/DDM) to diagnose Layer 1 optical faults.
- AI Fabric Orchestration: Experience deploying and managing AI clusters using Netris or Cisco Nexus Hyperfabric AI to automate fabric provisioning and operations.

Certifications

Highly Desirable:

- NVIDIA-Certified Skilled: AI Networking (NCP-AIN)
- NVIDIA-Certified Associate: AI Infrastructure and Operations (NCA-AIIO)
- Cisco Certified Network Professional (CCNP) Data Center

Success Metrics (KPIs)

- Fabric Efficiency: Achieving >95% effective bandwidth efficiency on NCCL-test benchmarks across the provisioned cluster.
- Layer 1 Accuracy: Zero "ghost links" or unstable connections handed over to the Compute team (all bad cables identified during the burn-in phase).
- Ticket Velocity: Consistently meeting SLAs for network-related support tickets.
