Site Reliability Engineer Resume Summary Examples

SRE I (BS Computer Science, 2025; one-year SRE rotation at AWS) with hands-on production experience across EKS, Terraform, Prometheus, and PagerDuty. During my AWS rotation I owned the on-call rotation alongside a senior SRE for an 18-service compute team handling 4K req/sec at peak; participated in 6 P2 and 1 P1 incident response calls; co-authored 2 blameless postmortems with action items closed within SLA. Comfortable in Go and Python, the Linux internals expected at AWS SRE level (kernel namespaces, cgroups, network namespaces, eBPF basics via Cilium docs), and the SLO/error-budget vocabulary from the Google SRE Book curriculum the team ran me through. Targeting an SRE I or SRE II role on a hyperscaler-tier infra team.

Junior SRE (MS Computer Science, 2025; year-long graduate SRE program at a top-5 US bank) with focused experience in regulated production environments.
