You will develop the complete architecture of the interconnect that links GPUs within and between racks. This fabric enables sizable AI training and inference clusters to function as a single large accelerator. This system-level role involves teamwork across silicon, firmware, software, and topology development. You will translate workload and customer needs into architectural choices that will be part of NVIDIA’s flagship AI systems for years.\nWhat You'll Be Doing:\nDefine end-to-end system architecture for next-generation NVLink scale-up networks, from link and switch behavior through rack- and pod-level topology.\nConvert AI training and inference workload needs (LLM, MoE, and emerging model architectures) into specific networking, bandwidth, latency, and resiliency specifications.\nDrive architecture trade-off studies across performance, cost, power, and reliability, and build the models needed to justify those decisions with data.\nCollaborate closely with ASIC, firmware, software, and systems teams to ensure architecture decisions are implementable and land accurately in silicon and product.\nDevelop and use simulation and analytical models to validate architecture choices before committing to silicon.\nRepresent system architecture in multi-functional and customer-facing technical discussions, and serve as a technical expert on scale-up network behavior at scale. \nWhat We Need to See:\nBachelor's, Master's, or PhD in Computer Science, Computer Engineering, Electrical Engineering, or a related field, or equivalent experience.\n8+ years of industry experience in computer networking, system architecture, or high-performance interconnects.\nStrong grasp of network structure and dynamics at scale, including the impact of topology, congestion, and failure modes on distributed workload performance.\nExperience developing or using simulation/modeling environments to evaluate architecture trade-offs.\nStrong multi-functional collaboration skills - comfortable driving alignment across hardware, firmware, and software teams without direct authority over them. \nClear technical communication, including the ability to explain complex architecture trade-offs to both engineering and non-engineering collaborators.\nWays to Stand Out from the Crowd:\nDirect experience with NVLink, NVSwitch, or comparable scale-up interconnect technologies.\nHands-on experience with high-performance networking transports such as RoCE (RDMA over Converged Ethernet), including concepts low-latency transport, congestion control, and lossless fabric build.\nExperience with memory subsystem architecture, including memory hierarchies, cache coherency, and memory technologies such as HBM, DDR, or LPDDR.\nWorking knowledge of large-scale AI model architectures and how they map to network requirements.\nBackground in HPC or supercomputing-scale interconnect development.\nYour base salary will be determined based on your location, experience, and the pay of employees in similar positions. The base salary range is 184,000 USD - 287,500 USD for Level 4, and 224,000 USD - 356,500 USD for Level 5.You will also be eligible for equity and benefits.\nApplications for this job will be accepted at least until October 8, 2026.This posting is for an existing vacancy.\nNVIDIA uses AI tools in its recruiting processes.\nNVIDIA is committed to fostering an inclusive work environment and proud to be an equal opportunity employer.
