How to become a Site Reliability Engineer in India

A site reliability engineer applies software engineering to operations: defining SLOs, spending error budgets deliberately, running incident response, and automating away the repetitive work that keeps production upright. In India the role sits with product engineering rather than IT, owning on-call rotations, blameless postmortems, observability and capacity planning for services that must not go dark. To get there: Ability to write real code in Go, Python or Java, not only glue scripts, master skills like SLOs & error budgets, Incident response, Prometheus & Grafana, Kubernetes, gain experience through internships or projects, and apply to roles that match your level.

An error budget is the unreliability an SLO permits — a 99.9% monthly target allows roughly 43 minutes of failure. Teams spend that budget on risky releases and migrations. Once it runs out, the standing agreement is that feature work pauses and reliability fixes take priority, turning an argument about caution into a number both sides accepted in advance.

DevOps names a culture and a set of practices for collaboration between development and operations. Reliability engineering is a specific implementation with measurable rules: service-level objectives, error budgets, a cap on toil, and formal incident and postmortem processes. DevOps says close the gap; this discipline supplies the yardsticks for whether it actually closed.

On-call rotations usually run a week at a time with a primary and secondary responder, and paging tied to symptom-based alerts rather than to every metric. The responder acknowledges, stabilises and escalates as needed while communicating status, and someone else digs into root cause. Healthy teams track page volume and treat repeated night alerts as bugs.

Reliability engineers arrive by two routes: backend developers who grew interested in how systems behave under real traffic, and infrastructure specialists who learned to write proper software. Both must close the other half. Indian interviews typically cover coding, Linux and networking debugging, system design under failure, and a scenario about running a live outage.
