Software Engineering Manager, Business AI Agent

About the job

Like Google's own ambitions, the work of a Software Engineer goes beyond just Search. Software Engineering Managers have not only the technical expertise to take on and provide technical leadership to major projects, but also manage a team of Engineers. You not only optimize your own code but make sure Engineers are able to optimize theirs. As a Software Engineering Manager you manage your project goals, contribute to product strategy and help develop your team. Teams work all across the company, in areas such as information retrieval, artificial intelligence, natural language processing, distributed computing, large-scale system design, networking, security, data compression, user interface design; the list goes on and is growing every day. Operating with scale and speed, our exceptional software engineers are just getting started -- and as a manager, you guide the way.

With technical and leadership expertise, you manage engineers across multiple teams and locations, a large product budget and oversee the deployment of large-scale projects across multiple sites internationally.

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. We support and partner with the commerce ecosystem, from large retailers to small local merchants, to give them the tools, technology and scale to thrive in today’s digital world.Individual pay is determined by factors including job-related skills, experience, and relevant education or training.
