Senior Software Engineer, AI/ML, Quality, Applied AI

Google's software engineers develop the next-generation technologies that change how billions of users connect, explore, and interact with information and one another. Our products need to manage information at a massive scale, and extend well beyond web search. We're looking for engineers who bring fresh ideas from all areas, including information retrieval, distributed computing, large-scale system design, networking and data storage, security, artificial intelligence, natural language processing, UI design and mobile; the list goes on and is growing every day. As a software engineer, you will work on a specific project critical to Google’s needs with opportunities to switch teams and projects as you and our fast-paced business grow and evolve. We need our engineers to be versatile, display leadership qualities and be enthusiastic to take on new problems across the full-stack as we continue to push technology forward.

As a part of the Customer Engagement Suite (CES), you will work on an AI-powered customer service solution on the Google Cloud platform serving major contact center service providers, large enterprises, and Google's own products like YouTube.

You will work on agent assist, the core pillar built by the CES agent assist team, which is a high-impact product designed to significantly boost human agent productivity and customer satisfaction while dramatically reducing operational costs. You can find more information about Agent Assist on our product page and is now powered by state-of-the-art LLMs and Agentic AI. You will leverage LLMs and agentic AI techniques, in close collaboration with Conversational Agent, Vertex LLM and GDM teams.Applied AI builds conversational agents deployed at a large-scale that achieve very meaningful results in the real world. Some examples include the customer agent built for large call center environments, to fast food ordering managed by our Food AI agent. The team is transforming how enterprises connect with customers through the power of AI. We also offer unique experiences for team members where you get to work directly with the model builders (Google DeepMind / Vertex), learn and work with brilliant AI leaders, and have access to Global 1000 customers via our existing Google Cloud relationships. The opportunity in this space is tremendous.
