Base Salary
$180k - $225k/yr
Responsibilities
- Build analytical, cycle-level Python models of AI inference workloads on next-generation GPNPU hardware.
- Analyze compute, memory bandwidth, interconnect, pipelining, tensor placement, tiling, local memory residency, and data movement across memory tiers.
- Model sharding and collective boundary communication across multi-die systems.
- Represent vision and LLM workload characteristics including operators, sparsity, routing, quantization, and low-precision numeric formats.
- Calibrate models against an instruction-set simulator and profiling traces to meet accuracy targets.
- Write and defend evidence-based technical studies that inform architecture and product decisions.
- Balance single-stream latency against scaled-throughput performance and own workload models end to end.
