Summary
👤
Senior🎓
Top SchoolZach Zimmerman is a Staff Software Engineer in Mountain View with 11 years of experience specializing in ML systems, performance engineering, and high-performance computing. He blends production-facing performance work at Google—optimizing large embedding, diffusion, and LLM training/serving on accelerators—with deep research credentials from a PhD where he helped pioneer the Matrix Profile and created GPU-accelerated algorithms like SCAMP and GPU-STOMP. Zach has a track record of scaling algorithms to extreme throughput (e.g., computing a quintillion z-normalized distances on 40 V100 GPUs) and shipping low-level performance libraries such as NVIDIA’s cuTensor during internships. He moves seamlessly between research, production optimizations, and systems engineering, bringing both theoretical insight and practical accelerator-focused implementation experience.
