Site Reliability Engineer (SRE)
Keep systems reliable, secure, and scalable.
What is a Site Reliability Engineer (SRE)?
Site Reliability Engineer (SRE) focuses on Design and build solutions in the field.. You design infrastructure, manage reliability, and ensure systems stay available under load. The work blends automation, monitoring, and operations.
An SRE day mixes coding and operations: you write automation, manage IaC, tune monitoring, and run deploys; you also review recent incidents, update runbooks, and respond to on-call pages. Much time goes to reducing repeatable toil—turning ad-hoc fixes into tested playbooks—so when alerts arrive you act from instrumentation and rehearsed procedures rather than guesswork.
