Senior AI/Data Center Network Fabric Architect

NVIDIA Corporation; Italia; Remote; EUR 120,000 - 180,000; Full time

Job summary

NVIDIA Corporation is seeking a Senior Network and Fabric Operations Solutions Architect to join the Infrastructure Specialist Team. You will own fabric operations across NVLink/NVSwitch, validate Day-1 deployments, and guide multi-tenant GPU estates from handover to production.

The role requires deep data-center networking expertise, hands-on experience with InfiniBand, UFM, Spectrum-X Ethernet, and Linux switch stacks. Strong consulting, scripting, and observability skills are essential.

Qualifications

• BS/MS/PhD in Computer Science, Electrical/Computer Engineering, Physics, Mathematics, or related fields, or equivalent experience.
• 5+ years of professional experience in data centre networking, fabric engineering or large-scale network operations roles.
• Deep understanding of data centre network architectures and RDMA fabrics—InfiniBand and RoCE/Ethernet—including topology and routing design, congestion control, lossless/QoS configuration, and troubleshooting across NICs, switches and high-speed interconnects.
• Hands-on experience with InfiniBand and UFM, Spectrum-X Ethernet, Cumulus Linux and/or SONiC, ConnectX and BlueField NICs/DPUs, and NVLink/NVSwitch systems—ideally including NMX-C / NMX-M partition operations on NVL72-class platforms.
• Proficiency in Python and Bash scripting, configuration management and IaC tools (e.g. Ansible, Terraform), GitOps-based network configuration and firmware/upgrade management for large fleets, and observability stacks (Grafana, Loki, Prometheus).

Responsibilities

• Own Day 2 fabric operations across NCP fleets: NVLink/NVSwitch partition management on GB200/GB300 systems.
• Own the switch software and firmware lifecycle—Cumulus Linux, SONiC and switch-OS upgrades with staged rollout plans.
• Support Day 1 fabric validation and acceptance: InfiniBand/UFM bring-up, Ethernet configuration, cabling and link-health verification.
• Minimise handover to production time and consolidate validation across hardware bring-up and partner teams.
• Drive fabric reliability at fleet scale: telemetry, fault detection, remediation, and MTBI improvement.
• Provide consultative guidance and hands-on troubleshooting across the fabric stack and run knowledge transfer to partner teams.
