Site Reliability Engineer (SRE)

HIGH DemandLOW AI RiskGROWING in SL· Rs.175k+ /mo

For engineers who want to be responsible for keeping systems alive at scale — SREs apply engineering discipline to reliability, treating uptime as a software problem to be solved.”

About This Role

Ensuring the reliability and uptime of large-scale web services and systems.

A Day in the Life

Site Reliability Engineers (SREs) apply software engineering principles to infrastructure and operations — building automation to reduce toil, defining and measuring service reliability (SLOs/SLIs), and ensuring production systems are available, performant, and resilient.

Define and monitor SLOs/SLIs/Error Budgets for production services
Build automation to eliminate repetitive operational toil
Respond to and lead production incidents using structured runbooks
Conduct post-mortems and implement systemic reliability improvements
Build and improve observability systems (metrics, logs, traces)
Collaborate with engineering teams on reliability design reviews
Manage capacity planning and performance testing

Work Environment

HYBRIDTeam: SMALLCASUALRemote: HIGH

Large tech company or product platform. SRE teams exist alongside development teams. On-call is a core part of the role.

Typical hours: 48h/week · WLB score 6/10 · OCCASIONAL overtime

On-call rotation is standard. Premium companies manage on-call well with clear escalation paths and respectable pager loads.
