Take AI developer-tooling prototypes from Google Labs to production
This role sits on the AIDA (AI Developer Assistant) team inside Google Labs, building full-stack AI products that change how software is designed and maintained — from rapid prototyping through scaling into robust, launched systems, working cross-functionally with Google DeepMind. The JD calls for real full-stack range (backend in Java/Python/Golang/C++, frontend in JS/TS/HTML/CSS) plus the judgment to kill or scale a prototype.
