Network Infrastructure Architect

The role

You will architect network fabrics for hyperscale AI clusters from RDU-accelerated servers to global-scale deployments. You will own fabric, interconnect, and spine-leaf design decisions and partner with hardware engineering, supply chain, and customer-facing teams.

What you will do

• Architect network fabrics that power hyperscale AI clusters
• Own fabric, interconnect, and spine-leaf design decisions
• Partner with hardware engineering, supply chain, and customer-facing teams
• Translate workload requirements into platform roadmaps
• Apply a vendor-agnostic approach to platform selection
• Bring platforms from concept through deployment

Required qualifications

• 12+ years designing or architecting infrastructure for hyperscale, AI, HPC, or large-scale data center environments
• Deep working knowledge of AI cluster networking, including InfiniBand, RoCEv2, Ethernet-based AI fabrics, 400G/800G interconnects, and GPU-to-GPU east-west traffic patterns
• Experience with lossless Ethernet designs, including QoS, ECN, PFC, congestion management, buffer tuning, and failure-domain isolation
• Strong understanding of spine-leaf architectures and associated technologies (VXLAN, EVPN, BGP, ECMP, underlay/overlay design, network automation)
• Familiarity with high-speed optics and cabling for AI clusters, including 400G/800G transceivers, DAC/AOC, fiber topology, and link budgets
• Experience translating customer and workload requirements into product requirements, platform roadmaps, and architecture tradeoffs
• Vendor-agnostic approach to platform selection and interoperability across switch, NIC, optical, and fabric ecosystems
• Ability to partner across hardware engineering, supply chain, operations, and customer-facing teams to bring platforms from concept through deployment

Nice to have

• Experience with AI compute platforms: GPU/accelerator systems, rack-scale compute, NVLink/NVSwitch-class fabrics, PCIe/CXL, DPUs/IPUs
• Understanding of rack-level power, thermal, mechanical, and serviceability requirements, and how network choices drive them (NIC selection, cabling density, PCIe lane allocation)
• Background in large-scale fleet operations: lifecycle management, reliability, observability, telemetry, field issue resolution

Benefits

• Base salary plus equity
• 95% premium coverage for employee medical insurance
• 77% premium coverage for dependents
• Health Savings Account (HSA) with employer contribution
• Dental, Vision, Short/Long term Disability, Basic Life, Voluntary Life, and AD&D insurance plans
• Flexible Spending Account (FSA) options like Health Care, Limited Purpose, and Dependent Care
• Headspace subscription
• Gympass+ membership
• One Medical membership
• Counseling services with an Employee Assistance Program

Before you apply

• You must submit an application form for each position for which you believe you are qualified
