What is a site reliability engineer?

Site Reliability Engineers (often abbreviated as SREs or Site R) are professionals who combine software engineering and systems administration skills to ensure that large-scale, highly complex systems are reliable, scalable, and efficient. They focus on automating operations tasks, monitoring system health, responding to incidents, and improving infrastructure through code. SREs often work closely with development and IT teams to balance the need for rapid software delivery with the stability and reliability of production systems.
