About the Role
Site Reliability Engineering (SRE) is what you get when you treat system operations as a software engineering problem. The mission of the Site Reliability Engineering team is to ensure uninterrupted service for Klaviyo customers and act as a force multiplier for Klaviyo product teams to deliver better software faster.
The SRE team builds foundational backend services as well as tooling and automation to allow product teams to release and scale their software reliably and predictably. SREs are team players who embed themselves within product teams as needed to advance the architecture and performance of software systems and train their peers in topics such as debugging distributed systems, building self-healing applications and eking out every drop of performance possible.
As a Site Reliability Engineer you will own foundational Klaviyo services and make a big impact on the productivity of our product engineering teams.
