Rockstar🎓
Top SchoolXin Liu is a senior software engineering manager in Seattle with 18+ years of engineering experience and a decade leading teams at scale across major consumer platforms.

Prior roles at Facebook and Microsoft show deep expertise in high-throughput ad serving, targeting, messaging infrastructure and search pipelines, often building teams and systems from scratch. Xin blends hands-on technical depth in ML-driven moderation and ads systems with cross-functional leadership, and is known for turning complex, data-heavy research into production-grade, low-latency services. A pragmatic problem-solver, she repeatedly tackles the hardest parts of safety and integrity engineering that sit at the intersection of scale, latency, and trust.
