Senior Scale-Up Network System Architect

Responsibilities

• Define end-to-end system architecture for next-generation NVLink scale-up networks, from link and switch behavior through rack- and pod-level topology.
• Convert AI training and inference workload needs (LLM, MoE, and emerging model architectures) into specific networking, bandwidth, latency, and resiliency specifications.
• Drive architecture trade-off studies across performance, cost, power, and reliability, and build the models needed to justify those decisions with data.
• Collaborate closely with ASIC, firmware, software, and systems teams to ensure architecture decisions are implementable and land accurately in silicon and product.
• Develop and use simulation and analytical models to validate architecture choices before committing to silicon.
• Represent system architecture in multi-functional and customer-facing technical discussions, and serve as a technical expert on scale-up network behavior at scale.
• What We Need to See
• Bachelor's, Master's, or PhD in Computer Science, Computer Engineering, Electrical Engineering, or a related field, or equivalent experience.
• 8+ years of industry experience in computer networking, system architecture, or high-performance interconnects.
• Strong grasp of network structure and dynamics at scale, including the impact of topology, congestion, and failure modes on distributed workload performance.
