The skills section was a wall of 46 logos and keywords: Docker, Kubernetes, Helm, Jenkins, GitLab CI, GitHub Actions, ArgoCD, Terraform, Pulumi, Ansible, Chef, Puppet, Prometheus, Grafana, and on it went. Below it sat a single job, two years of \u201csupported deployments.\u201d We passed on it in under a minute. The candidate probably knew a good chunk of those tools. The page gave us no way to tell which ones.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">DevOps hiring has a specific shape. The people reading your resume are usually engineers themselves, or recruiters working off a list an engineer wrote, and both groups are hunting for the same signal: have you actually run something in production, broken it, and fixed it? Everything on the page should help answer that.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Start with the skills section, and make it smaller<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Hiring managers in this field read skills sections suspiciously. A long list reads as keyword stuffing. A short, grouped list reads as someone who knows where their depth sits.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Group by function, and put the tools you\u2019d be comfortable defending in a whiteboard interview first. A layout that works:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Cloud:<\/strong> AWS (EC2, EKS, IAM, S3, RDS), some GCP<\/li>\n\n\n\n<li><strong>Containers and orchestration:<\/strong> Docker, Kubernetes, Helm<\/li>\n\n\n\n<li><strong>CI\/CD:<\/strong> GitHub Actions, Jenkins, ArgoCD<\/li>\n\n\n\n<li><strong>Infrastructure as code:<\/strong> Terraform, Ansible<\/li>\n\n\n\n<li><strong>Observability:<\/strong> Prometheus, Grafana, Loki<\/li>\n\n\n\n<li><strong>Scripting:<\/strong> Bash, Python, some Go<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The phrase \u201csome GCP\u201d is doing real work there. It tells the reader you\u2019ve touched it and won\u2019t oversell it, which builds trust for the rest of the list. I\u2019d rather see an honest qualifier than a tool I\u2019ll have to probe for 10 minutes and find nothing behind.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Leave out the things every Linux user knows (vim, SSH, Git basics) unless the job ad specifically names them. Git can stay if you mention a branching strategy you\u2019ve managed, since that\u2019s a different skill from committing code.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Match the job description, too. If a posting says \u201cGitLab CI\u201d and you\u2019ve used GitLab CI, write GitLab CI, not \u201cCI\/CD pipelines.\u201d Applicant tracking systems do literal matching more often than people assume, and the recruiter running the first pass is often comparing words, not concepts.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Bullets: what changed because you were there<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Most DevOps resumes fail at the bullet level. People describe duties. \u201cResponsible for maintaining CI\/CD pipelines.\u201d \u201cWorked with Kubernetes clusters.\u201d Those sentences would fit anyone on the team, including the people who did very little.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A bullet that gets an interview names the system, what you did to it, and what got better. Numbers help when you have them, but they have to be real, because a good interviewer will ask how you measured the change.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Some before and after pairs:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Before:<\/strong> Maintained Jenkins pipelines for microservices. <strong>After:<\/strong> Moved 14 services from a shared Jenkins server to GitHub Actions with reusable workflows, which cut average build time from about 18 minutes to 7 and ended the Monday morning queue backlog.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Before:<\/strong> Managed AWS infrastructure using Terraform. <strong>After:<\/strong> Split a single 3,000-line Terraform state into per-environment modules with remote state in S3 and DynamoDB locking, so two engineers could apply changes in staging without blocking each other.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Before:<\/strong> Set up monitoring and alerting. <strong>After:<\/strong> Built Prometheus alerting rules for the payments API and routed them through Alertmanager to PagerDuty; rewrote 30 noisy alerts so on-call pages dropped to roughly one a night.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The \u201cafter\u201d versions are longer, and that\u2019s fine. Two lines per bullet is normal for this kind of role. What you\u2019re avoiding is the five-line bullet that tries to tell the whole project history.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you\u2019re struggling to turn a vague duty into something specific, an <a href=\"https:\/\/quillbot.com\/ai-resume-builder\">ai resume builder<\/a> can help with the rewriting step. I\u2019d use it as a drafting partner, not a ghostwriter. Paste in your rough notes, something like \u201cmigrated Jenkins to GitHub Actions, 14 services, builds faster, about 18 min to 7 min, reusable workflows,\u201d and ask for two or three bullet versions. Then pick the one that sounds like you and fix any detail it got wrong. These tools are good at sentence structure and at trimming filler. They know nothing about your actual systems, so every number and tool name has to come from you.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A prompt that tends to produce usable results:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Rewrite this as a resume bullet for a DevOps engineer role. Keep it under 35 words. Start with a strong verb, name the tools, and end with the measurable result. Notes: moved staging and prod to separate Terraform workspaces, before this one bad apply took down both, no incidents of that kind in 8 months since.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Projects matter more than you\u2019d think<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For anyone with under three years of experience, the projects section often carries the resume. Even senior people benefit from one or two, especially if their day job sits on a proprietary platform they can\u2019t show anyone.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The project needs to look like infrastructure, not like a tutorial. \u201cDeployed a to-do app on Kubernetes\u201d is what a course gives you. Hiring managers have seen it hundreds of times. A project that stands out usually has one of three qualities: it runs continuously, it solves an operational problem, or it shows a decision you had to make and defend.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Some project ideas that tend to land well:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>A homelab with real uptime.<\/strong> A small k3s cluster on two or three cheap machines or Raspberry Pis, managed with Ansible, with Prometheus and Grafana watching it. Mention how long it\u2019s been running and one thing that broke. \u201cDisk on node two filled with container logs after six weeks; added log rotation and a disk usage alert\u201d is more convincing than any feature list.<\/li>\n\n\n\n<li><strong>A full pipeline for a real app.<\/strong> Take any small open source application and build the whole path: tests in CI, container build, image scanning with Trivy, push to a registry, deploy via ArgoCD to a cluster, with a rollback you\u2019ve actually tested.<\/li>\n\n\n\n<li><strong>Infrastructure as code with environments.<\/strong> A Terraform repo that stands up a VPC, an EKS or GKE cluster, and a database across dev and prod workspaces, with a README that explains why you structured modules the way you did.<\/li>\n\n\n\n<li><strong>A cost or reliability fix.<\/strong> If you ran something on a personal AWS account and noticed the bill creeping, write up what you changed. Cost work is underrated on junior resumes.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">On the resume itself, give each project two or three lines and a link to the repository. Put the link where the reader can find it fast. And make the repository presentable before you send anything: a README with an architecture diagram (even a rough one), setup steps, and a short \u201cwhat I\u2019d change next\u201d section. That last part shows judgment, which is a big piece of what interviewers are testing.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>A sample project entry<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Self-hosted CI\/CD platform<\/strong> (GitHub link) Built a GitOps setup for a three-service Python app: GitHub Actions runs tests and builds images, Trivy blocks images with critical CVEs, ArgoCD syncs to a k3s cluster. Wrote a rollback runbook and tested it by deliberately shipping a broken release.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That last sentence about deliberately breaking things gets more interview questions than anything else in the entry, in my experience, because it\u2019s what working engineers do.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Certifications: which ones get noticed<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Certifications are a contested topic in DevOps circles. Some engineers dismiss them completely. Many hiring pipelines, especially at consultancies, managed service providers and large enterprises, still use them as a filter, and some partner programs require a certain number of certified staff. So they matter for getting past the first screen, even if they matter less once you\u2019re talking to an engineer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The ones that come up most often in job postings:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Certification<\/th><th>What it signals<\/th><th>Who it fits<\/th><\/tr><\/thead><tbody><tr><td>CKA (Certified Kubernetes Administrator)<\/td><td>You can operate a cluster under time pressure; the exam is hands-on<\/td><td>Anyone targeting Kubernetes-heavy roles<\/td><\/tr><tr><td>CKAD (Certified Kubernetes Application Developer)<\/td><td>Comfort deploying and debugging workloads<\/td><td>Developers moving toward platform work<\/td><\/tr><tr><td>AWS Certified DevOps Engineer Professional<\/td><td>Deep AWS automation and deployment knowledge<\/td><td>Mid-level engineers in AWS shops<\/td><\/tr><tr><td>AWS Solutions Architect Associate<\/td><td>Broad AWS literacy<\/td><td>A common first cloud cert<\/td><\/tr><tr><td>Microsoft Azure DevOps Engineer Expert (AZ-400)<\/td><td>Azure pipelines and governance<\/td><td>Enterprise and Microsoft-centric employers<\/td><\/tr><tr><td>HashiCorp Terraform Associate<\/td><td>Baseline IaC knowledge<\/td><td>Juniors; a light but recognised signal<\/td><\/tr><tr><td>Google Professional Cloud DevOps Engineer<\/td><td>SRE practices on GCP<\/td><td>GCP-focused teams<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">If you have budget and time for one, the CKA probably gives the best return for most people, partly because the exam is performance-based and interviewers know it can\u2019t be passed by memorising question banks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">List certifications in their own short section with the year earned. Don\u2019t put them at the top of the page unless you have very little work experience; for experienced engineers, they belong after experience and projects. If a cert has expired, either renew it or drop it. An expired cert from 2019 suggests you stopped keeping up.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One more thing about certifications: if you\u2019re currently studying for one, you can list it as \u201cin progress, exam scheduled for December.\u201d Only do that if the exam really is booked.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Layout and length<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">One page if you have under about five years of experience. Two pages after that, if the second page carries real weight. Nobody in hiring has ever complained that a junior candidate\u2019s resume was too short.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The order I\u2019d use for most people:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Name, location (city is enough), email, GitHub, LinkedIn<\/li>\n\n\n\n<li>Two-line summary (optional, and only if it\u2019s specific)<\/li>\n\n\n\n<li>Skills, grouped<\/li>\n\n\n\n<li>Experience<\/li>\n\n\n\n<li>Projects<\/li>\n\n\n\n<li>Certifications<\/li>\n\n\n\n<li>Education<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Career changers coming from sysadmin, QA, or support roles can swap experience and projects, putting the DevOps work first. If you came from a support background, keep that job on the page; incident handling and talking to frustrated users are part of on-call life, and many teams value it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Avoid two-column templates with skill bars (\u201cKubernetes: 80%\u201d). Percentages mean nothing to a reader, and column layouts sometimes scramble when an ATS parses them. A plain single-column layout with clear headings works everywhere.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For the summary, skip adjectives. \u201cPassionate, results-driven DevOps engineer\u201d is noise. Something like \u201cPlatform engineer with three years running EKS clusters for a fintech app; most recent work on cost reduction and alert hygiene\u201d gives the reader a reason to keep going.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Common mistakes I keep seeing<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Listing every tool from every tutorial.<\/strong> Covered above, but it remains the most frequent problem. Cut anything you couldn\u2019t explain for five minutes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>No numbers anywhere.<\/strong> You don\u2019t need a metric on every bullet. You need a few, and they need to be honest. Build time, deployment frequency, number of services, cost per month, alert volume, recovery time after an incident: pick the ones you actually tracked.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Hiding the GitHub link.<\/strong> If your projects carry your application, the link should be in the header and next to each project. Pinned repositories on your GitHub profile should be the ones you\u2019d want discussed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Copy-paste from the job ad.<\/strong> Matching keywords is good. Pasting whole requirement sentences into your bullets is obvious and reads badly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Generic AI phrasing.<\/strong> This one is newer. Recruiters now see many resumes where every bullet starts with \u201cSpearheaded\u201d or \u201cOrchestrated\u201d and ends with \u201cdriving efficiency.\u201d If you use an <a href=\"https:\/\/quillbot.com\/ai-resume-builder\">ai resume builder<\/a> or any writing assistant, read the output out loud and replace any phrase you wouldn\u2019t say in a stand-up meeting. Keep the structure it gives you; swap the vocabulary for your own.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Ignoring the cover note.<\/strong> Many applications have a short text box. Two sentences about why this specific team\u2019s stack interests you will often be read before the resume is.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Tailoring for different DevOps roles<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cDevOps engineer\u201d covers a lot of jobs. A posting for a site reliability engineer leans toward observability, incident response, SLOs and error budgets. A platform engineer posting leans toward internal developer tooling, Kubernetes, and self-service infrastructure. A \u201cDevOps engineer\u201d role at a 20-person startup may mean you\u2019re also the person who fixes the office Wi-Fi.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Keep a master resume with every bullet you\u2019ve ever written, then build a version per role type. For an SRE role, lead with your incident and monitoring bullets. For a platform role, lead with the CI\/CD and IaC work. The changes might be small, perhaps reordering four bullets and swapping the summary, but the reader\u2019s first impression changes a lot.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When you\u2019re applying to a company that publishes engineering blog posts, read two of them. If they write about migrating to ArgoCD and you\u2019ve done that, move that bullet to the top.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>FAQ<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Should I include a home lab if I already have DevOps work experience?<\/strong> Only if it shows something your job doesn\u2019t. If you work in an AWS-only shop and the homelab runs bare-metal Kubernetes, it fills a gap. Otherwise the space is better spent on work bullets.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>How do I describe work done under NDA?<\/strong> Describe the system\u2019s shape without names: \u201ca payments platform handling card transactions for a regional bank\u201d is fine. Interviewers understand confidentiality.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Do I need a degree listed?<\/strong> List it if you have one. Plenty of DevOps engineers don\u2019t, and a strong projects section and a CKA cover most of the same ground for many employers.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Before you hit send<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Print the resume, or open it as a PDF on your phone, and read only the first third of the page. That\u2019s roughly what gets read on a first pass. If that section doesn\u2019t show a specific system you\u2019ve run and a specific result you produced, move something up. Then check every link works while logged out of GitHub, because private repositories make a surprisingly common dead end.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A few years ago I helped a friend screen applicants for a junior platform role, and one resume stuck with me.
