Rockstar🎓
Top SchoolLi-wen Chang is a Distinguished Research Scientist and Engineering Director specializing in AI compilers, distributed training/inference, and SW–HW co-design for GPUs and AI ASICs, currently setting roadmap and driving production-scale model deployment at ByteDance Seed. With eight years of industry experience built on a deep academic foundation from UIUC, she has translated MLIR/LLVM-based research into systems that run LLMs and generative models across tens of thousands of accelerators and millions of users. Previously at Microsoft Cloud & AI, she led compiler and runtime efforts in ONNX Runtime, delivering multi-fold cost and performance gains for production services. She combines hands-on compiler/kernel synthesis work (including Triton extensions and confidential ASIC backends) with cross-disciplinary leadership across programming languages, hardware architecture, and distributed systems. Notably, she has incubated agentic coding systems and a model performance estimation program, moving prototypes into internal production. Based in Issaquah, WA, she is passionate about building high-performance, production-ready AI infrastructure and strong technical teams.
