Enable integration with:

Open-source ML frameworks (e.g., PyTorch, ONNX, XNNPACK, MLAS)

Apply advanced optimizations:

SIMD/vectorization
Cache-aware execution
Parallel execution strategies

Benchmarking & Performance Engineering
Optimize CPU-centric ML benchmarks such as:

Geekbench AI
Internal benchmarking suites

Establish performance baselines and track improvements across hardware generations
Perform competitive analysis and performance positioning

Required Qualifications

Strong background in:

Computer Architecture / Systems Programming
Machine Learning fundamentals

Proficiency in:

C/C++ (mandatory)

Experience with:

Performance profiling, benchmarking, and optimization

Preferred Qualifications

Experience with:

QEMU or equivalent simulators
ML kernel development (GEMM, convolution, attention)

Knowledge of:
