Role Description
World Wide Technology is seeking a Technical Solutions Architect (TSA) – AI High-Performance Networking to join our AI & Data practice, specifically on the High-Performance Architectures (HPA) practice within Global Solutions & Architecture (GS&A). You will be WWT's subject matter expert on the network fabrics powering AI Factories — designing InfiniBand, Spectrum-X Ethernet, and RoCE architectures alongside partners including NVIDIA (Mellanox), Arista, Cisco, Juniper, and Broadcom to deliver lossless, low-latency networks for the most ambitious AI workloads on the planet. You will sit at the intersection of WWT's NVIDIA, hyperscaler, and enterprise customer engagements — translating customer business outcomes into validated, scalable fabric designs that move models from pilot to production. Expect to spend your time pairing with customer architects, leading whiteboard sessions in WWT's Advanced Technology Center (ATC), and shaping the reference designs the rest of WWT's field organization takes to market.
