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. With your technical expertise you will manage project priorities, deadlines, and deliverables. You will design, develop, test, deploy, maintain, and enhance software solutions. Google Shopping Search Ads aims to make Google the best place for users’ purchases, price-comparison, and shopping informational needs. Our features and models impact the shopping commercial unit on google.com, often the top of the page for a shopping-related query. We also impact commercial units on image search, where users may have a more visual or in-depth shopping journey. Our mission is to improve the matches between users' queries and tasks and the product listing ads that we show. We use state of the art machine learning techniques to predict human ratings of ads and incorporate those predictions into filtering and ranking of ads.
