Summary
Matthew Siu is a design engineer in San Francisco with a decade of experience blending human-centered design, interactive interfaces, and software engineering to make complex information more usable. He has moved between research and product roles—working on mechanistic interpretability and model-control interfaces with ML Alignment scholars, prototyping creativity-support environments at NYU, and building B2B information tools and novel writing environments with teams like Broadcast and Andy Matuschak. Matthew’s work often sits at the intersection of language models, RL, and interface design, focusing on tooling that surfaces and manipulates feature space for end users. He combines hands-on engineering (from React and Node to prototyping novel UX) with research-grade curiosity, evidenced by collaborations in interpretability and creative writing tools. Notably, he built automated tooling to bridge large React codebases and design workflows, reflecting a practical knack for turning messy code and data into usable design artifacts.
