About the Job

Google Cloud's software engineers develop the next-generation technologies that change how billions of users connect, explore, and interact with information and one another. 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 Cloud's needs with opportunities to switch teams and projects as you and our fast-paced business grow and evolve. You will anticipate our customer needs and be empowered to act like an owner, take action and innovate. 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.

The mission of our team is to deliver reliable, efficient, and high-performance end-to-end network communication stacks, making it easy to build distributed systems at Google. Stubby is a battle-tested Google internal Remote Procedure Call (RPC) stack which integrates with a variety of tools and services, and is widely used at Google. gRPC is an RPC stack which was google-developed as open source, and serves as a bridge between Cloud and Google Prod. Our team is responsible for the Stubby and gRPC RPC stacks in Google production (predominant source of Google network traffic).
