Who You ll Work With

SREs at Arista combine strong software and systems engineering with a passion for operating production systems at scale. As an SRE you ll be part of the team responsible for our global service fleet.

What You ll Do:

CloudVision is deployed on Kubernetes across global regions using Spinnaker for our CI/CD pipeline. Our tech stack runs on GKE, using HBase/Hadoop as main distributed database and storage layer, ElasticSearch for powering search data, ClickHouse for fast real time queries of flow data, our own Kafka-based distributed real time stream processing layer for analytics, and TensorFlow for ML analysis. Our monitoring system is built on top of Prometheus, Grafana, Loki, and other OSS tools.
As a Senior SRE, you ll be responsible for our global CloudVision service fleet. This includes:

• Build, deploy safely and incrementally and operate critical production systems with focus on scalability, reliability, observability, performance and security.
• Monitor, support and enhance product deployment experience across services.
• Build automation to remove toil and efficiently operate production systems.
• Proactively monitor, respond to, and enhance alerts and set up automated alert handling
• Create and maintain the incident response runbooks.
• Build and deploy new systems with scalability, reliability, and observability as primary requirements
• Triage platform/infrastructural issues and help Arista software engineers in their triages. Engage with 3rd party vendor support.
