Summary
Qingyi Lu is a Senior Machine Learning Engineer with nine years of experience building low-latency, high-throughput systems for ad ranking and delivery across TikTok and Meta. With an MS in Computer Science from Brown and a strong dual background in mathematics, he bridges rigorous academic research—on topics like statistical binning and phylogenetics—with production ML engineering. He has shipped optimization work for web ads and product ranking, and is comfortable across distributed systems, algorithm design, and large-scale data analysis. A seasoned educator and mentor, Qingyi spent years as a TA and math tutor, sharpening his ability to translate complex concepts for teams. He pairs deep theoretical instincts with practical implementation experience, having written tooling and packages in R/Python during research projects and interned at Goldman Sachs on software engineering problems. Based in the San Francisco Bay Area, he’s seeking a creative, innovation-focused software engineering role where applied ML and system design meet.
