About the role

Key responsibilities & impact

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 including:
- compute throughput and utilization
- memory systems (HBM, cache hierarchies, bandwidth constraints)
- data types and precision tradeoffs (FP16, BF16, FP8, etc.)
- interconnect and scaling behavior.
Run benchmarks and profiling to validate hardware performance against workload requirements.
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 and roadmap decisions.

Requirements

What you’ll need

Have deep expertise in GPU or accelerator architecture, including performance and power tradeoffs.
Understand AI workload behavior and how it interacts with hardware design choices.
Are comfortable engaging directly with silicon vendors at a technical architecture level.
Have hands-on experience with benchmarking, profiling, and performance analysis.
Can translate low-level hardware details into system-level and workload-level impact.
Are equally comfortable in theory (architecture) and practice (measurement/validation).
Thrive in environments where you bridge internal teams and external partners.
