Summary
👤
Senior🎓
Top SchoolShenxiu Liu is a Senior Staff engineer and technical leader with 11 years of experience building revenue-critical GenAI and ads systems, most recently founding and scaling Meta’s Monetization GenAI org. He specializes in algorithm-system co-design—bridging RLHF and large-scale infrastructure—to align generative creative with CTR/CVR signals and drive measurable revenue gains. His work spans stable post-training systems, multi-modality pre-training, and inference optimizations that delivered 3–8x fleet efficiency across 20k+ GPUs. A computational physicist by training (Stanford M.S., Peking University B.S. in Physics & Math), he applies numerical-stability and high-MFU techniques from physics to solve fundamental RL training and inference bottlenecks. Notably, he moved novel algorithms like FlowGRPO and GRPO from research into production and mentored multiple ICs and managers into senior roles while building privacy- and scale-conscious AutoML and serving platforms.
