Infrastructure Engineer Resume Tips

What recruiters look for, keywords that get past ATS, and what skills to highlight in 2026.

A Day in the Life

An Infrastructure Engineer in DevOps typically begins the day triaging overnight alerts from monitoring platforms like Datadog or PagerDuty, reviewing infrastructure drift in Terraform state files, and syncing with platform or SRE teams on ongoing incident postmortems. Midday involves hands-on work: writing or reviewing IaC modules, tuning Kubernetes cluster autoscaling policies, optimizing CI/CD pipeline runtimes, or capacity planning across multi-cloud environments. By afternoon, the focus often shifts to cross-functional collaboration — reviewing architecture proposals, documenting runbooks, mentoring developers on infrastructure self-service patterns, and grooming the backlog of reliability or cost-optimization tickets.

ATS Keywords to Include

Recruiters and hiring software scan for these — make sure they appear naturally in your resume.

Example Resume Bullets

Strong bullet points use action verbs, specific context, and measurable outcomes. Adapt these for your own experience.

• • Designed and maintained a modular Terraform codebase managing 200+ AWS resources across 4 environments, reducing provisioning time by 65% and eliminating configuration drift through enforced GitOps workflows.
• • Architected a multi-region EKS platform serving 50+ microservices with 99.97% uptime, implementing Cluster Autoscaler and Karpenter to cut compute costs by $220K annually through dynamic node rightsizing.
• • Built end-to-end CI/CD pipelines in GitHub Actions for 15 engineering teams, integrating SAST, container image scanning, and automated rollback logic that reduced failed production deployments by 40%.
• • Led migration of legacy VM-based workloads to Kubernetes, containerizing 30 services over 6 months and enabling zero-downtime deployments via blue/green strategies managed through ArgoCD.
• • Established an observability foundation using Prometheus, Grafana, and Datadog, defining SLOs for 12 critical services and reducing mean time to detection (MTTD) from 18 minutes to under 3 minutes.

Emerging Skills Worth Adding

Skills becoming highly valued in the next 2–3 years — early adoption signals forward-thinking candidates.

• → Platform Engineering — building Internal Developer Platforms (IDPs) using tools like Backstage to enable infrastructure self-service
• → eBPF-based observability and networking using Cilium or Tetragon for deep kernel-level visibility without instrumentation overhead
• → AI/ML infrastructure provisioning — managing GPU node pools, model serving infrastructure, and MLOps pipelines on Kubernetes
• → Supply chain security practices including SLSA frameworks, SBOM generation, Sigstore/Cosign image signing, and policy enforcement with OPA/Kyverno
• → FinOps integration — embedding cloud cost attribution, rightsizing automation, and Spot/Preemptible instance orchestration directly into IaC workflows
