Senior🎓
Top SchoolRyan Bae is a Senior Machine Learning Engineer with nine years of experience building end-to-end ML systems for cloud and on-device use, currently focused on engagement modeling for Reddit’s monetization org. He has deep expertise in content understanding, ads ranking, and NLP/NLU workflows including fine-tuning and evaluating large language models, and has published work on an LLM-based retrieval system presented at CIKM 2025. At Microsoft he bridged product and research by prototyping on-device models for Windows, applying mixed-effects statistics to fairness problems, and creating large-scale pattern-less personal data detection for telemetry. Comfortable across applied statistics, feature engineering, and production pipelines, he uniquely combines aerospace-trained analytical rigor with practical ML delivery across consumer and ad platforms. Based in Seattle, he blends research-grade experimentation with measurable product impact, especially in scenarios where privacy, device constraints, and ranking performance intersect.
