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.
As an ML Engineer on the Travel Ads team, you will be at the forefront of integrating highly relevant travel ads into AI Overviews/AI Mode and web search experiences. You will bridge the gap between generative AI and core ads infrastructure. You will build and optimize the deep learning models powering ads ranking and retrieval alongside integrating LLMs.
You will leverage user intent and contextual signals to deliver ads that feel like a natural, helpful extension of the user's travel planning journey. This is a unique opportunity to apply your expertise in recommendation/search system and deep learning technology (Adbrain, TensorFlow, JAX) to scale features, drive significant business impact, and shape the future of travel discovery.
Google Ads is helping power the open internet with the best technology that connects and creates value for people, publishers, advertisers, and Google. We’re made up of multiple teams, building Google’s Advertising products including search, display, shopping, travel and video advertising, as well as analytics. Our teams create trusted experiences between people and businesses with useful ads. We help grow businesses of all sizes from small businesses, to large brands, to YouTube creators, with effective advertiser tools that deliver measurable results. We also enable Google to engage with customers at scale. ****
