About the job

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.

A Retrieval Engine takes a user's search query, first finding relevant documents and then ranking them by importance. Document retrieval is performed either through traditional methods (e.g., looking up words in an inverted index) or by converting queries and documents into embeddings and finding relevant documents via nearest neighbor search.

Responsibilities

• Improve Google's core search engine for flexibility, customizability, and efficiency.
• Develop code that scales to the world's largest search engine and is as efficient as possible.
• Write code that scales demands while remaining flexible for quick iteration and experimentation.
