Main responsibilities

• Contribute to the technical requirements and end-to-end delivery of AI infrastructure — compute, networking, storage, power, and cooling — not just the accel…
• Evaluate, select, and qualify AI hardware platforms (GPUs, custom ASICs, SmartNICs, storage) based on real workload requirements and first-principles analysis
• Design and validate rack-scale GPU systems: multi-node topologies, high-speed interconnects (NVLink, InfiniBand, RoCE), power distribution, and thermal manag…
• Run hands-on qualification: benchmarking, stress testing, failure mode analysis, and vendor RCA — you close the loop yourself
• Assess and qualify ODM/OEM server platforms; engage directly with vendors and work through the full technical qualification cycle
• Translate AI product and workload requirements into precise infrastructure specifications
• Identify gaps in the existing infrastructure stack and drive solutions across hardware, firmware, software, and operations
• Stay ahead of the AI hardware landscape — new silicon, new interconnects, new form factors — and bring informed, opinionated recommendations
• Build tooling and automation to support qualification workflows, performance analysis, and ongoing operational visibility
• Communicate your results and updates through blog posts and internal talks
