Hardware Architecture Expert - 3P

Responsibilities

• ▹Engage deeply with silicon vendors (e.g. NVIDIA & AMD) on GPU and accelerator architecture tradeoffs
• ▹Analyze and interpret performance, power, and efficiency characteristics of next-generation hardware
• ▹Translate vendor specifications into expected real-world performance for AI workloads
• ▹Evaluate architectural aspects: compute throughput/utilization, memory systems (HBM, cache hierarchies, bandwidth), data types/precision (FP16, BF16, FP8), interconnect and scaling behavior
• ▹Run benchmarks and profiling to validate hardware performance
• ▹Lead early bring-up and evaluation of engineering sample (ES) silicon
• ▹Partner with performance modeling and system architecture teams to align measured vs. modeled behavior
• ▹Provide actionable feedback to vendors to influence future silicon design

Requirements

• ▹Deep expertise in GPU or accelerator architecture, including performance and power tradeoffs
• ▹Understands AI workload behavior and how it interacts with hardware design choices
• ▹Comfortable engaging directly with silicon vendors at a technical architecture level
• ▹Hands-on experience with benchmarking, profiling, and performance analysis
• ▹Can translate low-level hardware details into system- and workload-level impact
• ▹Equally comfortable in theory (architecture) and practice (measurement/validation)

Nice to have

• ▹Experience working with or at companies like NVIDIA & AMD or similar silicon providers
• ▹Familiarity with AI accelerator stacks, including GPUs, custom ASICs, or emerging architectures
• ▹Experience with early silicon bring-up or hardware validation workflows
• ▹Strong understanding of memory systems (HBM, DDR, cache hierarchies) and data movement bottlenecks
• ▹Experience with performance tooling, microbenchmarks, and workload characterization
