role: Staff Software Engineer (IC6)
loc: San Francisco Bay Area
I build backend systems for large-scale ML and generative AI products — real-time inference under production latency, cost, and integrity constraints, evaluation infrastructure for generative models, and ML internationalization for low-resource markets. Fifteen-plus years across high-stakes domains: risk systems on Wall Street, and consumer AI (currently at Meta) serving hundreds of millions of people daily.
