Job description

Meet the Team

Cisco ThousandEyes is a Digital Experience Assurance platform that empowers organizations to deliver flawless digital experiences across every network—even the ones they don’t own. Powered by AI and an unmatched set of cloud, internet, and enterprise network telemetry data, ThousandEyes enables IT teams to proactively detect, diagnose, and remediate issues before they affect end-user experiences. ThousandEyes is deeply integrated across the Cisco technology portfolio, delivering AI-powered assurance insights within Cisco’s Networking, Security, Collaboration, and Observability portfolios. Our distributed Site Reliability Engineering team of approximately nine engineers owns the availability, latency, performance, efficiency, monitoring, emergency response, and capacity planning of the platform while partnering closely with application development teams. We believe in operations, infrastructure, and everything as code, creating a collaborative and pragmatic environment where engineers can manage large-scale systems that receive hundreds of millions of messages per hour.

Your Impact

Design and operate large-scale, highly available distributed systems that allow the ThousandEyes platform to process a constantly growing volume of telemetry data. Use AI Tooling to write high-quality code and automated solutions that enable fast, reliable releases, reduce operational expense, and allow our infrastructure and platforms to scale thoughtfully across regions. Evaluate the scalability, resiliency, performance, and security of production services, including testing high-availability and disaster-recovery measures and addressing potential single points of failure. Troubleshoot complex issues across infrastructure and platform services, participate in the on-call rotation and incident-management process, and turn root-cause findings into lasting reliability improvements. Collaborate with application development teams and other stakeholders to meet internal Service Level Objectives and customer-facing Service Level Agreements while improving the tools, frameworks, platforms, and automation used throughout the service lifecycle.
