Founding Machine Learning Lead at Epsilon Labs
Mountain View, California, United States
Summary
👤
Senior🎓
Top SchoolRui An is a founding machine learning lead based in Mountain View with 11 years of experience bridging physics research and production ML systems. Trained as a physicist (PhD) and postdoc, he built deep learning and computer-vision pipelines for neutrino experiments at Fermilab and IceCube, then translated that expertise to NLP and recommendation products at hireEZ. He has hands-on experience shipping LLM-based applications and multimodal models, leading NLP teams and improving recall and ranking in production. Skilled in C++ and Python, Rui designs end-to-end data reconstruction, analysis, and model engineering workflows that span research prototypes to deployed services. Notably, he has a track record of winning applied ML challenges (Facebook parsing competition) and building domain-specific CNNs for particle ID—an uncommon blend of experimental physics and modern ML productization.
