What Is a Site Reliability Engineer (SRE)?
Site Reliability Engineers apply software engineering principles to operations problems, ensuring systems are reliable, scalable, and efficient. SREs use formal constructs like Service Level Objectives (SLOs), error budgets, and playbooks to manage reliability systematically. The role was pioneered at Google and has become essential across tech companies managing large-scale distributed systems.
What makes this role unique: Unlike traditional ops roles, SREs approach operations as a software problem—building tools, automating toil, and using error budgets to balance reliability with development velocity.
Best suited for: Engineers who enjoy systems thinking, automation, and solving complex reliability challenges at scale. Strong programming skills combined with deep infrastructure knowledge are essential.
