Site Reliability Engineer (SRE)
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
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.
