Site Reliability Engineer - Ireland

As a Site Reliability Engineer at Arista Networks, you'll be responsible for managing the global CloudVision service fleet, which involves building CI/CD pipelines, improving operational processes through automation, and ensuring system security and disaster recovery. You'll also play a pivotal role in leading postmortems and being part of a global on-call team, making this a challenging yet rewarding position.

To qualify for the Site Reliability Engineer position at Arista Networks, you should hold a BS/MS degree in Computer Science or a related field, along with at least 4 years of software engineering experience. Familiarity with distributed databases, SaaS environments, and various technologies like Kubernetes and Prometheus will also enhance your application.

Advancing your career as a Site Reliability Engineer at Arista Networks involves continuing to improve your skills in software and systems engineering, gaining experience with our tech stack, and actively participating in innovative projects. The inclusive environment at Arista allows for growth, and your contributions are valued, which can lead to more opportunities within the company.

Site Reliability Engineers at Arista Networks work with an impressive tech stack that includes Kubernetes, HBase/Hadoop, ElasticSearch, ClickHouse, and TensorFlow, among others. This sophisticated environment allows you to utilize the latest tools and technologies to enhance the performance and reliability of our services.

At Arista Networks, you can expect a work culture that values diversity of thought and encourages creativity and innovation. The collaborative environment promotes open communication, and you'll find yourself part of a supportive team dedicated to achieving excellence and maintaining high standards in all our projects.

The CI/CD lifecycle is crucial for a Site Reliability Engineer as it allows for seamless integration and continuous deployment of services. By streamlining code updates and automating deployment processes, we ensure faster delivery of new features while minimizing system downtime, leading to better product reliability.

Disaster recovery planning is vital in the Site Reliability Engineer role. I would explain my previous experience, highlighting projects where I developed recovery strategies, established backup processes, and conducted regular drills to test our recovery procedures, ensuring quick restoration of services.

When it comes to incident management, I believe in a blameless postmortem approach. After an incident occurs, I focus on analyzing the root causes, systematically documenting findings, and collaborating with the team to implement preventative measures to enhance overall system reliability.

Essential tools for monitoring and maintaining systems include Prometheus for metrics collection, Grafana for visualization, and various logging and alerting tools. I would explain how I leverage these tools to gain insights into system performance, diagnose issues promptly, and ensure operational excellence.

In the event of a significant outage, I would first ensure all key stakeholders are informed while mobilizing the on-call team for immediate investigation. Once the cause is identified, I'd implement fixes and communicate updates to both stakeholders and the affected users, followed by a thorough review and documentation of the incident.

For capacity planning, I utilize historical data and key service indicators to project future resource needs. By analyzing traffic patterns and application usage, I can make informed decisions tailored to the service's growth trajectory while ensuring that we remain prepared for unforeseen traffic spikes.

I once identified a repetitive manual testing procedure that delayed deployment times. By automating this process with CI/CD tools, I reduced testing time significantly, which improved deployment efficiency and reliability, demonstrating the importance of automation in a Site Reliability role.

I have extensive experience working with Kubernetes to manage our containerized applications. I leverage Kubernetes for its scalability and reliability features, ensuring seamless deployment and orchestration of microservices in a cloud environment, which is essential for a Site Reliability Engineer.

Security in cloud-based applications is a top priority. I follow best practices such as regular vulnerability assessments, employing feature flags, and adhering to a solid incident response strategy, ensuring that security measures are integrated into the entire development pipeline.

I am drawn to the Site Reliability Engineer position at Arista Networks because of your commitment to innovation and excellence. I admire your diverse work culture, the use of cutting-edge technology, and the impact I could have on a globally recognized service like CloudVision. I am excited about the prospect of contributing my skills to such a dedicated team.
