How long should a DevOps engineer resume be?+
One page for most engineers; two only if you have roughly 8+ years or led large platform initiatives. Recruiters skim for a few seconds, so front-load delivery and reliability metrics and keep it single-column so ATS parses cleanly.
Which certifications matter most for DevOps roles?+
The Certified Kubernetes Administrator (CKA), HashiCorp Terraform Associate, and an AWS certification (Solutions Architect Associate or DevOps Engineer Professional) carry the most weight. List them near the top and repeat the underlying skills in your bullets — the cert plus demonstrated use is what convinces recruiters.
How do I write a DevOps resume with no professional DevOps title yet?+
Lead with what you have automated. A homelab Kubernetes cluster, Terraform modules on GitHub, and a CI/CD pipeline for a personal project all demonstrate the core skills. Quantify them — nodes managed, minutes saved per deploy — the same way you would paid work.
Should I list every tool I've touched?+
No. Prioritize the stack named in the job description and the tools you can discuss under pressure. A focused list — one cloud, Kubernetes, Terraform, your CI/CD tool, and your observability stack — beats a 40-item keyword wall you can't defend in an interview.
