A Site Reliability Engineer (SRE) is a role that focuses on ensuring the reliability, availability, and performance of complex software systems and infrastructure. SREs bridge the gap between traditional software development and operations teams, combining their expertise to build and maintain scalable, reliable, and efficient systems.
SRE takes the tasks that have historically been completed manually by operations teams, and instead gives them to SRE engineers who use software and automation to ensure software applications remain reliable and are highly scalable. A Site Reliability Engineer is responsible for how code is deployed, configured, and monitored, as well as the availability, latency , change management, emergency response and capacity management of services in production.
