A template for engineers who build reliable, scalable infrastructure that ships fast.

← All Examples

What Does a DevOps Engineer Actually Do?

A DevOps Engineer builds and maintains the infrastructure, pipelines, and tooling that let software teams ship code fast and reliably. Day-to-day work involves maintaining CI/CD pipelines in GitHub Actions or Jenkins, managing Kubernetes clusters, writing Terraform for infrastructure-as-code, responding to production incidents, and working with developers to improve deployment reliability. You'll work inside product companies, consulting firms, financial institutions, and cloud-native startups. You report to a Head of Platform, Engineering Manager, or CTO depending on company size.

What Recruiters Look For

DevOps CVs must show infrastructure scale, automation achievements, and reliability metrics. Recruiters want to see your cloud certifications, the scale of systems you manage, and your deployment velocity improvements.

Key Skills to Include

AWS/GCP/Azure, Kubernetes, Docker, Terraform, CI/CD (GitHub Actions, Jenkins), monitoring (Prometheus, Grafana, Datadog), Python/Bash scripting, and GitOps.

Common Mistakes

Listing tools without context. Everyone uses Docker. Show that you containerised 200+ microservices reducing infrastructure costs by 35%. Quantify deployment frequency, uptime SLAs, and incident response times.

Formatting Tips

One to two pages. Use a Technical Skills section grouped by category: Cloud, Orchestration, CI/CD, Monitoring, Scripting. Include your cloud certifications prominently.

Top 5 Interview Questions — DevOps Engineer

1Walk me through how you would design a CI/CD pipeline for a microservices application.
Cover source control triggers, build stages, automated testing gates, container image builds, registry management, environment promotion, and rollback capability. Show you think about security scanning and secrets management too.
2How do you manage infrastructure as code across multiple environments?
Talk about Terraform workspaces or Terragrunt for environment separation, state backend management with remote state in S3 or GCS, and how you handle sensitive variables. Mention module reuse and drift detection.
3Describe how you have approached incident response and on-call in a previous role.
Show your alerting philosophy — alert on symptoms not causes — and describe your runbooks, escalation paths, blameless post-mortem process, and how you improved MTTR over time.
4How would you secure a Kubernetes cluster in a production environment?
Cover RBAC, network policies, pod security admission, image scanning with Trivy or Snyk, secrets management with Vault or AWS Secrets Manager, and audit logging. Show you think about the attack surface.
5Tell me about the most complex infrastructure problem you have solved.
This is your chance to show depth. Be specific about the problem, the technologies involved, your diagnosis process, and the outcome. Numbers help — latency improved by X%, cost reduced by Y%.

How to Tailor Your CV

Spotify, Cloudflare, and Monzo want deep Kubernetes expertise, strong SRE principles, and experience with high-availability systems at scale. Consultancies like Thoughtworks value breadth and the ability to upskill client engineering teams alongside delivering technical work. For banks and financial services firms like JPMorgan or Deutsche Bank, compliance, audit trail, and security hardening of pipelines are just as important as deployment automation.
