What is a site reliability engineer?

A Site Reliability Engineer (SRE) is a professional who applies software engineering principles to infrastructure and operations problems. Their primary goal is to create scalable and highly reliable software systems, often bridging the gap between development and IT operations. SREs automate tasks, monitor system health, respond to incidents, and work to improve system reliability and performance. They also help define service level objectives (SLOs) and ensure systems meet customer expectations for uptime and availability.
