Key Skills

What to Include on a Site Reliability Engineer Resume

• A concise summary that states your site reliability engineer experience level, strongest domain, and the business problems you solve.
• A skills section that mirrors the job description language for Kubernetes, Prometheus/Grafana, Terraform, Python.
• Experience bullets that connect site reliability engineer, SRE, infrastructure automation to measurable outcomes such as cost savings, faster delivery, better quality, or improved customer results.
• Tools, platforms, certifications, and methods that are current for software engineering roles.
• Recent projects that show ownership, cross-functional work, and a clear result instead of generic responsibilities.

Sample Experience Bullets

• Improved uptime for a high-traffic platform by building automated failover mechanisms, self-healing infrastructure, and comprehensive health checks across 40+ services. Reduced unplanned downtime and gave on-call engineers clearer recovery paths during incidents
• Reduced mean time to recovery from 45 minutes to 8 minutes by automating common runbook procedures and eliminating noisy alerts that were hiding real issues behind a wall of false positives. The on-call team's stress levels dropped noticeably after the cleanup
• Wrote the SLO framework that 15 services now use, including clear definitions of SLIs, error budget policies, and automated tracking dashboards. Each team has concrete reliability targets they review weekly and the framework has become part of the planning process
• Automated certificate rotation, capacity planning scripts, deployment rollbacks, and 12 other toil-heavy operational tasks that were previously done manually. The automation eliminated about 200 hours of repetitive monthly work across the SRE and platform teams
• Ran the chaos engineering program by designing and executing 50+ failure injection scenarios per quarter including network partitions, disk fills, and dependency outages. Discovered 30 previously unknown failure modes and fixed them before they caused real incidents
• Served as primary on-call for all production infrastructure on a weekly rotation, coordinating incident response across engineering teams and writing detailed postmortems with root cause analysis for every P0 and P1 incident. The postmortem process led to 85% of action items being completed within 2 weeks
• Managed Kubernetes clusters across 3 AWS regions handling all production workloads, performing version upgrades, node pool resizing, and troubleshooting pod scheduling issues during capacity crunches. Cluster upgrades are now zero-downtime thanks to rolling update policies
• Built Grafana dashboards and Prometheus alerting rules for 40+ services with tiered severity levels and clear escalation paths. Became the team's go-to resource for observability architecture questions and helped other teams set up their own monitoring
• Worked with development teams to define appropriate resource requests and limits for their Kubernetes deployments, right-sizing containers based on actual usage data. The effort prevented about 15 OOM-related outages per quarter and reduced overall cluster waste by 25%
• Designed the disaster recovery strategy with automated region failover, tested it quarterly through full DR drills, and maintained RPO of 5 minutes and RTO of 15 minutes. The most recent drill completed successfully with all services recovering in under 12 minutes
• Built a capacity planning model that uses historical traffic patterns and growth projections to forecast infrastructure needs 6 months ahead. The model prevented 3 capacity-related incidents by triggering preemptive scaling before traffic exceeded cluster limits
