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.
The Replication team (also known as Placer team) owns Placer product and CNS2 Asynchronous Replication area, currently being under active development.
Placer is a low-overhead system service that manages replication of and access to sets of CNS files.
CNS is Google's internal, cluster-level, exabyte-scale filesystem. Used by teams like Youtube, BigQuery and Search. It is a critical building block of Google services. CNS2 is a new generation of CNS with a location-agnostic namespace, native data replication, transparent tiering and flexible regional placement policies, among other features.
Behind everything our users see online is the architecture built by the Technical Infrastructure team to keep it running. From developing and maintaining our data centers to building the next generation of Google platforms, we make Google's product portfolio possible. We're proud to be our engineers' engineers and love voiding warranties by taking things apart so we can rebuild them. We keep our networks up and running, ensuring our users have the best and fastest experience possible.
