About The Position

The Business Agent team powers Google’s Agentic Commerce strategy by building the AI platform behind seamless merchant-consumer interactions across Search, YouTube, Ads, and Messaging. We turn conversational AI into measurable commerce outcomes for millions of businesses worldwide. We solve complex, high-scale AI issues to build fast, reliable, and intelligent agent experiences. Optimize multi-turn AI reasoning loops and tool-calling pipelines for real-time responsiveness. Develop robust data pipelines for the Merchant Knowledge Library to power accurate Retrieval-Augmented Generation (RAG). Build automated evaluation frameworks and AutoRaters to continuously measure conversation quality and factuality at scale. People shop on Google more than a billion times a day - and the Commerce team is responsible for building the experiences that serve these users. The mission for Google Commerce is to be an essential part of the shopping journey for consumers - from inspiration to to a simple and secure checkout experience - and the best place for retailers/merchants to connect with consumers.
