You have built pipelines that reduced deploy times from hours to minutes, managed infrastructure at scale, and eliminated entire classes of production incidents. Yet the ATS scoring your resume does not know any of that — it only sees whether your resume contains the exact tool names and platform vocabulary the posting requires.
DevOps job postings are more tool-specific than almost any other engineering role. The same pipeline competency built on GitHub Actions versus Jenkins scores differently against a posting that names one but not the other. This is the specific, avoidable gap that filters out strong DevOps candidates.
CI/CD tools are separate ATS keywords: GitHub Actions, Jenkins, CircleCI, GitLab CI, Tekton, and ArgoCD are each independent. Writing "CI/CD pipeline experience" scores zero against any of them. Cloud platforms must also be specific: AWS, Azure, and GCP are not interchangeable keyword searches.
Within cloud platforms, service names matter: EKS, ECS, EC2, Lambda, RDS, S3 (AWS); AKS, Azure DevOps, ACR (Azure); GKE, Cloud Run, Cloud Build (GCP). A DevOps role at an AWS shop may specifically filter for EKS and Lambda — writing 'AWS experience' covers none of those.
Are your CI/CD tools and cloud services named specifically in your resume?

Kubernetes vocabulary is a hard filter at most modern DevOps roles: Kubernetes (not just K8s — both), Helm, kubectl, namespaces, RBAC, HPA, Ingress controllers, service mesh (Istio, Linkerd). If the posting specifies any of these, they must appear in the resume.
IaC tools are another frequent hard filter: Terraform, Ansible, Pulumi, CloudFormation, Chef, Puppet. Monitoring stack vocabulary also matters: Prometheus, Grafana, Datadog, PagerDuty, ELK/EFK stack. Name every tool in your stack.

The DevOps candidate who names every tool they have used outperforms the one who relies on category descriptions — even if their actual pipeline depth is identical. Specificity is the differentiator that ATS systems reward.

The most common reason is category language. "CI/CD experience" scores zero against GitHub Actions, Jenkins, or CircleCI — each is a separate ATS keyword. Cloud platforms must also be specific (AWS vs Azure vs GCP) and individual services named.
List both. "Kubernetes" and "K8s" are different strings to an ATS. Use "Kubernetes (K8s)" in your skills section so both forms appear — each can match a separate search.
Terraform, Ansible, Pulumi, CloudFormation, and Helm are the most common IaC keywords in DevOps job postings. List every tool you have used in production — each is an independent ATS filter.
