AI Network Support Engineer

About the role

Regional GPU Infrastructure Operations

• Own the operational health and availability of all NVIDIA DGX B300 / GB300 and HGX B300 / GB300 GPU cluster environments at the regional site — achieving and sustaining ≥99.9% infrastructure uptime
• Serve as the single point of operational accountability for the regional site — escalation owner for all P1 and P2 infrastructure incidents
• Manage and coordinate 24/7 operations coverage across AI Systems, Network & Security, Platform, and Site Resilience engineering teams
• Oversee physical data center operations including power, cooling, physical security, and facility management in coordination with data center facility teams
• Ensure all GPU cluster operations comply with NVIDIA NCP reference architecture operational standards and certification requirements
• Maintain operational readiness for all compute, storage, fabric, and software stack components across the regional portfolio

Network Design & Fabric Architecture

• Design and deploy NVIDIA NCP-compliant InfiniBand NDR (400Gb/s) and highspeed Ethernet (400GbE/800GbE) fabrics for B300 and GB300 Blackwell GPU cluster environments
• Architect front-end, back-end, and storage network segmentation aligned to NVIDIA DGX SuperPOD and HGX reference topologies
• Design and implement RoCE v2 (RDMA over Converged Ethernet) configurations for AI workloads requiring low-latency, lossless transport
• Configure and validate NVIDIA Quantum-2 InfiniBand switches, Spectrum-4 Ethernet switches, and ConnectX-7/BlueField-3 DPU/SmartNIC deployments
• Implement NUMA topology-aware network placement and hardware-enforced tenant isolation at the DPU/SmartNIC level for multi-tenant AI environments
• Design BGP, OSPF, and ECMP routing architectures for scale-out AI fabric interconnects and data center interconnects (DCI) links

Manage Firewall Security

• Design, implement, and maintain secure network infrastructure including LAN/WAN, firewalls, VPNs, SD-WAN, and cloud connectivity to ensure high availability, performance, and business continuity across all sites and data centers.
• Monitor, detect, and respond to security threats and incidents through proactive threat intelligence, vulnerability assessments, IDS/IPS management, and SIEM platforms — ensuring the organization's critical assets remain protected at all times.
• Enforce and maintain network security policies, access controls, and segmentation strategies while ensuring compliance with industry frameworks including ISO 27001, NIST CSF, and CIS benchmarks across all network layers.
• Collaborate with IT, infrastructure, and operations teams to evaluate and integrate emerging network and security technologies, support capacity planning, and drive continuous improvement of the organization's overall security posture.
