Senior Software Engineer, Full Stack, Labs

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 handle information at 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.

We are looking for an experienced Software Engineer to join our team in Mountain View. You will play a critical role in building, scaling, and optimizing the backend infrastructure that powers the Lotus experience.

You'll be responsible for designing and implementing robust, scalable systems to handle everything from data ingestion and agentic workflows to content generation and API services.

While the primary focus is backend, you'll be open to contributing to our Flutter/Dart frontend, especially in areas involving generative UIs/UX.

Labs is a group focused on incubating early-stage efforts in support of Google’s mission to organize the world’s information and make it universally accessible and useful. Our team exists to help discover and create new ways to advance our core products through exploration and the application of new technologies. We work to build new solutions that have the potential to transform how users interact with Google. Our goal is to drive innovation by developing new Google products and capabilities that deliver significant impact over longer timeframes.
