Job Description
Key Responsibilities
- Operate and support data center network infrastructure, including high-speed switching, routing, optics, cabling, and transceivers in on-prem environments.
- Manage IP addressing, VLANs, VRFs, and segmentation constructs to support secure and scalable network operations.
- Support modern data center architectures including leaf-spine fabrics, ECMP-based forwarding, and VXLAN overlay/underlay environments, including day-2 operations.
- Execute network changes, maintenance activities, upgrades, and validation tasks with strong focus on availability, reliability, and operational discipline.
- Troubleshoot L1L3 issues impacting network performance, including optics/cabling faults, interface errors, MTU mismatches, routing behavior, packet loss, congestion, retransmissions, and ECMP pathing.
- Diagnose latency, throughput, drop, and east-west traffic performance issues in high-performance environments.
- Use Linux CLI, logs, and common network troubleshooting tools to investigate incidents and validate infrastructure behavior.
- Partner with compute, storage, application, and platform teams to isolate whether bottlenecks originate from the network, host, or application layer.
- Develop and maintain network automation artifacts such as templates, playbooks, and scripts to improve consistency and reduce manual tasks.
- Work with DevOps teams to integrate network automation into existing deployment and operational workflows without owning the DevOps platform.
- Support network observability and telemetry, including streaming telemetry, flow data, and performance-focused monitoring capabilities. They should be very familiar with end-to-end monitoring/alerting of production network(s). The specific tool we'll use in this environment is NetQ but something equivalent would be ok.
- Contribute to continuous improvement of network operations through standardization, documentation, and operational best practices.
Must-have (Required Qualifications)
Must have:
- 35+ years in data center or enterprise network operations/support
Must have real production support experience. - CCNA-level knowledge or equivalent hands-on networking foundation
Enough to be productive quickly without teaching basic networking. - Strong L2/L3 and TCP/IP fundamentals
Proven troubleshooting across L1L3: physical, switching, routing, forwarding. - Experience supporting on-prem physical infrastructure
Switches, optics, cabling, transceivers, port health, physical fault isolation. - Strong Linux operational comfort
CLI, logs, interfaces, routing tables, packet tools, basic host/network troubleshooting. - General network monitoring and observability experience
Must be strong in end-to-end production monitoring, alerting, and fault isolation; NetQ-equivalent experience is acceptable. - Ability to troubleshoot performance issues across the traffic path
Latency, packet loss, congestion, MTU, retransmissions, ECMP pathing. - Understanding of modern data center architecture
Leaf-spine, ECMP, VLAN/VRF segmentation, east-west traffic patterns for AI/HPC-style environments - Familiarity with underlay/overlay concepts in VXLAN environments
Enough to support day-2 operations and trace traffic logically and physically from point A to point B - Foundational knowledge of RDMA/RoCE concepts
Not deep design expertise, but enough to understand AI/HPC traffic sensitivity and why congestion behavior matters - Working exposure to automation/config management
Ansible-like repeatable playbooks, structured execution, and basic scripting for network operations. This should be operational exposure, not deep Python engineering. - Ability to collaborate with DevOps teams
Can work within existing tooling, workflows, and change practices. - Experience working in Agile/Kanban fashion
- Basic VPC-to-cloud awareness
Keep this as the lowest-priority must-have, since it is not central to the role you described.
Nice to have:
- Experience with NVIDIA NetQ or equivalent tools such as NMX
Helpful because NetQ aligns closely to the telemetry-heavy operating model used in Spectrum environments - Exposure to NVIDIA Spectrum switching platforms/ecosystem
Valuable, but teachable within a month for someone strong in core networking - In modern NVIDIA AI fabrics, telemetry and operations visibility are a core part of day-2 support, not an afterthought
- Hybrid networking experience
Cloud interconnectivity, routing, and policy across on-prem and cloud. - Production EVPN-VXLAN experience
MP-BGP EVPN, VNIs, anycast gateway, multi-tenancy/VRFs, day-2 troubleshooting - Good structured automation practices
Templates, version control, peer review, rollback discipline. - Basic Python depth
Useful, but now clearly lower priority than network troubleshooting, Linux, and monitoring. - Kubernetes networking familiarity
CNI, overlays, service networking, and interaction with the underlay. - Host-side NIC tuning experience
- Experience with high-performance or parallel storage networking
- AI/HPC networking experience
Rail-optimized, dual-plane, CLOS, GPU clusters, east-west optimization. - Exposure to GPU-cluster communication patterns such as NCCL
Strong differentiator, not a gate.
