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 the 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 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.
* Deploy new systems in a staged manner.
* Write postmortem documents and build solutions to avoid incidents from repeating.
* Plan and communicate maintenance windows on production systems.
* Work with Arista’s product development teams to identify infrastructural issues that are causing bottlenecks and limitations in their workflows. Design and implement solutions to resolve them.
* Survey and adopt best practices around infrastructure/platform to maintain secure, scalable and fault-tolerant systems.
* Implement solutions to scale the systems.
* Implement fault-tolerance and performance improvements to enhance availability.
* Study OSS design and implementation details for better triage and fix resolution.
Qualifications
* Bachelor's in Computer Science or Engineering + 5 years’ experience, MS in Computer Science or Engineering + 5 years’ experience, or equivalent work experience.
* Knowledge of one or more of Go, Python, or bash for automation workflows.
* Knowledge of Linux/UNIX administration and debugging.
* Hands-on experience operating software systems at scale (infrastructure, complex applications, etc.).
* Experience in server provisioning (storage and networking perspective).
* Strong problem solving and software troubleshooting skills.
* Experience with infrastructure-as-code.
* Desirable: experience with databases (e.g., PostgreSQL or equivalent), Docker and virtualization, monitoring stacks (Prometheus, Grafana), Artifactory/docker registry, CI/CD systems (GitLab, Spinnaker), and Terraform.
* Experience with container orchestration via Kubernetes.
