Stephen Murray

A Principal Engineer based in Boston, Massachusetts.

Building distributed systems and AI infrastructure at scale.

About Me

Principal-level engineer based in Boston with 17+ years building large-scale distributed systems. Currently focused on AI infrastructure and applied ML, from fault localization to LLM-powered operations agents.

I spent my late teens and early twenties touring in hardcore punk bands as a drummer. These days I build novel solutions to hard problems, mostly in the context of startups and tech. Node.js and Rust are my tools of choice, recently adding Zig to the mix.

Outside of work: video games, open source, tabletop gaming, game dev, tattoos, and dogs. Forever a hardcore/punk/emo kid and make zero apologies for it.
