GPU Cluster Architect

Accountabilities: Architect scalable GPU cluster topologies encompassing compute nodes, high-performance interconnects, storage systems, and control planes. Define and evaluate infrastructure architectures capable of supporting large-scale AI and machine-learning workloads across multiple data center sites. Model workload requirements for applications such as large language model training and inference, using latency, bandwidth, GPU density, and other performance factors to guide architectural decisions. Design and validate high-throughput, low-latency networking architectures at both POD and data-center scale, including InfiniBand and Ethernet-based environments. Work with network architecture teams to evaluate and validate technologies such as InfiniBand HDR/NDR and RoCEv2. Partner with storage engineering teams to optimize infrastructure for training datasets, checkpointing, and other demanding AI workloads. Analyze monitoring and telemetry signals to identify design issues, reliability risks, and opportunities for architectural improvement. Collaborate closely with site reliability, networking, storage, and data center engineering teams to operationalize, deploy, and scale infrastructure architectures. Contribute to automation and telemetry initiatives that improve the visibility, performance, and reliability of large-scale GPU environments. Make end-to-end architectural decisions that balance scalability, performance, reliability, operational complexity, and infrastructure efficiency. Requirements 5+ years of experience designing and architecting large-scale computing or GPU clusters. Deep understanding of modern GPU architectures, including NVIDIA, AMD, or comparable platforms. Strong experience with high-performance computing interconnects, particularly InfiniBand and RoCE. Solid background in systems architecture, networking, hardware infrastructure, and hardware reliability. Understanding of GPU cluster design principles, including compute topology, network architecture, storage integration, and control-plane considerations. Experience evaluating infrastructure performance and making architecture decisions based on workload characteristics such as latency, bandwidth, and compute density. Experience with scripting or software development for automation, telemetry, monitoring, or infrastructure tooling using languages such as Python or Go. Ability to analyze technical signals and operational data to identify infrastructure issues and inform design improvements. Strong cross-functional collaboration skills, with the ability to work effectively with networking, storage, site reliability, and data center engineering teams. Strong analytical and problem-solving abilities, with a practical approach to complex infrastructure challenges. Ability to work independently in a fast-moving environment while taking ownership of significant architectural decisions. Excellent communication skills and the ability to explain complex technical architectures and tradeoffs to technical stakeholders. Benefits Competitive compensation ranging from $184,000 to $318,000 OTE , including base salary and performance bonus. Equity in the form of RSUs may be available at certain salary grades. 100% company-paid medical, dental, and vision insurance for employees and their families. 401(k) plan with up to a 4% company match and immediate vesting. Paid parental leave: 20 weeks for primary caregivers and 12 weeks for secondary caregivers. Remote work reimbursement of up to $85 per month for mobile and internet expenses. Company-paid short-term disability, long-term disability, and life insurance. Remote work flexibility for U.S.-based employees. Career growth and ongoing learning opportunities. Opportunity to work on large-scale AI and machine-learning infrastructure projects. Collaborative, international environment with experienced engineering and AI professionals. High level of ownership and opportunities to contribute to technically ambitious infrastructure initiatives. Work environment that encourages innovation, initiative, and continuous improvement.
