Site Reliability Engineer (SRE) - Engineering Productivity

Who You’ll Work With

Arista Networks is looking for world-class Site Reliability Engineers passionate about driving systems reliability and scalability to provide the best possible development experience for our 2000+ person engineering team. You will be part of a fast paced, high caliber team building the internal systems and infrastructure used to build the routing and switching products driving the industry's largest data center networks. 

Arista’s Software Engineering team runs at a scale rarely found - TBs of source control, 60GB work trees with 1000s of developer branches in flight at any given time, over 400K daily build/test jobs and over 150 homegrown and cloud native services running on a 60 node Kubernetes cluster.  Operating these systems takes vigilance, responsiveness to alerts, and a steady stream of updates and bug fixes to keep things running smoothly and efficiently as well as to increase our ability to monitor, understand and visualize them. The SRE role will cover all aspects of our software development infrastructure, and may include monitoring, responding to, and enhancing alerts, working to unify and standardize our alerts, fine tuning code for scalability and performance, debugging problems and the addition of new features. You will own your projects from definition to deployment and customer interactions, and you will be responsible for the quality of everything you deliver. 

Working in Engineering Productivity (EngProd), you will collaborate and work with other engineers to design, build, scale, and operate the systems that the rest of Arista’s development teams use.  The EngProd team uses industry-standard systems like Ansible, Jenkins, Kubernetes, Grafana, Gerrit, MySQL, ElasticSearch, Google Cloud, and Redis and also internal systems that we’ve built from the ground-up to automate CI/CD, testing, analysis, and visualization.
