DevOps, SRE & Platform Engineer Resume: 50+ ATS Keywords That Get You Shortlisted

DevOps, SRE, and Platform Engineering postings share a huge vocabulary but each has its own emphasis: DevOps leans CI/CD and automation, SRE leans reliability and incident response, Platform Engineering leans internal tooling and developer experience. Mixing them up costs you Job Title Alignment (10% of your score). Here's how to keyword each correctly.

Cloud infrastructure (baseline for all three)

AWS, GCP, Azure, EC2, S3, VPC, IAM, Kubernetes, Docker, containerization, serverless, Lambda, load balancing, auto-scaling, multi-region, high availability.

Infrastructure as code

Terraform, CloudFormation, Pulumi, Ansible, Helm charts, GitOps, ArgoCD, configuration management.

CI/CD (core DevOps)

Jenkins, GitHub Actions, GitLab CI, CircleCI, build pipelines, artifact management, deployment automation, blue-green deployment, canary releases, rollback strategy.

Reliability & observability (core SRE)

SLIs/SLOs/SLAs, error budgets, incident response, on-call, postmortems, root cause analysis, Datadog, Prometheus, Grafana, PagerDuty, distributed tracing, chaos engineering, capacity planning.

Developer experience (core Platform Engineering)

Internal developer platform (IDP), self-service infrastructure, golden paths, service catalog, developer tooling, Backstage, platform-as-a-product, reducing cognitive load.

Security & compliance overlap

Secrets management (Vault), least-privilege IAM, SOC 2, vulnerability scanning, container security, network policies.

Quantify uptime and speed, not just tools

Weak: "Managed Kubernetes clusters and CI/CD pipelines." Strong: "Reduced deployment time from 45 to 6 minutes by rebuilding CI/CD on GitHub Actions; cut P1 incidents 35% by introducing SLO-based alerting across 40 services." Numbers on MTTR, uptime %, deploy frequency, and cost savings are exactly what hiring managers scan for after the ATS passes you through.

Title-match tip

If the posting says "Site Reliability Engineer" and your last title was "DevOps Engineer," don't silently rewrite your title — instead mirror the posting's language in your summary line and bullets ("reliability," "on-call," "error budgets") so both the ATS keyword match and the Job Title Alignment category pick up the overlap honestly.
