Suffian Khan is a Senior Software Engineer in Seattle with six years of industry experience building large-scale AI and cloud infrastructure, currently contributing to Google's GCP and AI supercomputer efforts. He brings deep HPC and performance-computing expertise from roles at Intel and Oak Ridge, where he architected distributed computation platforms, optimized physics and transistor modeling codes, and ran production-scale Monte Carlo jobs across tens of thousands of cores. At Microsoft and in open source he worked on AI inferencing and training frameworks—contributing CUDA/ROCm kernel fixes and training-resumption reliability to the widely used ONNX Runtime. A PhD-trained computational physicist with top grades in math and physics, he blends rigorous numerical modeling with practical API and tooling design (Python front-ends with C++ back-ends). Colleagues rely on him for diagnosing elusive parallel faults and squeezing order-of-magnitude performance gains from legacy codes. He is a U.S. citizen comfortable spanning research-grade simulation and production ML infrastructure.
