DevOps / SRE Engineer
Sample Resume & ATS Keywords
DevOps and SRE are one hiring market in practice, and recruiters search CI/CD tooling, infrastructure-as-code platforms, and reliability vocabulary (SLOs, error budgets, MTTR) as exact strings. A resume that says "managed infrastructure" without naming Terraform, Kubernetes, or the pipeline tool in use won't surface in that search — the example below shows what a keyword-complete, outcome-quantified version looks like.
All sample resume content on this page is original and illustrative — fictional candidates, realistic numbers. Use it as a pattern, not a template to copy verbatim.
Sample DevOps / SRE Engineer resume summary
What a parseable, keyword-complete professional summary looks like for this role:
DevOps / SRE Engineer with 6 years running CI/CD and infrastructure for a 60-engineer product org on AWS. Owns Terraform-managed infrastructure and a Kubernetes platform serving 400+ microservice deployments per week, with SLO-based alerting and a formal on-call rotation. Reduced MTTR 55% through incident-response tooling and holds deployment frequency at multiple times daily with a change failure rate under 3%.
Sample achievement bullets that pass ATS screening
Each bullet follows the pattern recruiters and parsers reward: exact keywords, a specific action, and a quantified outcome.
- Rebuilt CI/CD pipelines (GitHub Actions, ArgoCD) supporting 60 engineers, cutting average deploy time from 38 to 9 minutes and raising deployment frequency from twice weekly to multiple times daily.
- Migrated infrastructure for 40 services to Terraform-managed IaC across 3 AWS accounts, eliminating manual console changes and cutting environment-drift incidents to zero over 12 months.
- Defined SLOs and error budgets for 12 critical services, formalizing an on-call rotation and incident-response process that cut MTTR from 68 to 31 minutes.
- Led the postmortem process for a major outage affecting checkout, driving 9 corrective actions that prevented 2 recurrence attempts caught in staging over the following quarter.
- Containerized a legacy monolith and migrated it onto Kubernetes (EKS), enabling independent scaling that cut peak-load infrastructure cost 27%.
- Automated toil reduction for certificate rotation and secret management (Vault, Terraform), reclaiming an estimated 15 engineer-hours per month across the platform team.
- Ran chaos-engineering game days quarterly, surfacing 6 single points of failure before they caused production incidents.
- Held change failure rate under 3% for 18 consecutive months across 400+ weekly deployments by introducing progressive delivery (canary releases) via ArgoCD.

DevOps / SRE Engineer resume formatting: do this, not that
Do
- Name CI/CD tooling exactly: Jenkins, GitHub Actions, GitLab CI, ArgoCD, CircleCI — recruiters search the specific platform.
- Carry infrastructure-as-code and orchestration terms explicitly: Terraform, Ansible, Kubernetes, Docker.
- Use reliability vocabulary matched to the posting: SLOs, SLIs, error budgets, on-call, incident response, toil reduction.
- Quantify reliability outcomes: uptime improved, deployment frequency, MTTR reduced, change failure rate.
- Show ownership of both build (pipelines, IaC) and run (on-call, incident response) — postings increasingly expect both.
Don't
- Don't write "managed infrastructure" without naming the cloud, IaC tool, and orchestration platform.
- Don't report uptime without the reliability practice behind it — "improved uptime" needs an SLO, alerting, or incident-response change attached.
- Don't omit on-call and incident-response experience if you have it — it's a specific, searched SRE signal.
- Don't list every tool you've touched once — depth on the platform you actually run beats a long, shallow list.
- Don't skip deployment frequency and change failure rate — DORA metrics are now standard recruiter search terms.
