This job is no longer available. is the most popular website on the Internet. Our network has to operate at an unprecedented scale and reliability—around the world and 24/7. We oversee the web’s largest IP backbone and what is by far the biggest and most advanced cluster networking infrastructure on the planet. A huge amount of global Internet traffic depends on us, and on the technical masterminds who keep us running. Google’s NetworkArchitecture team defines and provides all manner of architectural elements, building blocks and technologies that allow Google's production networkinfrastructure to meet the needs of our nearly 1 billion users. Given the size and complexity of our network, we face a constant stream of interesting challenges. The ever-evolving set of technologies we use to take on these challenges are used by innovative and dynamic problem-solvers with expertise in all aspects of network management.

Network Architects ensure the continued enhancement of features in the Google production network. The Google network operates at scale while providing reliable service to Internet users throughout the world. The scale and complexity of Google's network generates a constant stream of interesting challenges which are solved by using an evolving set of technologies that require innovation in every aspect of networking.

In this role, your work will involve specifying the architecture and design guidelines for the Optical Network that interconnects Google’s Data Center to each other and to the internet as well as the optical connectivity between routers and transport equipment. You'll be responsible for effectively documenting and communicating these architectural guidelines through documented standards. You will also work closely with IP Architecture, Network Acquisition, Network Design, Deployment, and Operations teams to carefully consider and incorporate solutions to meet future needs.

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're always on call to keep our networks up and running, ensuring our users have the best and fastest experience possible.
