DevOps Engineer Job Description

Key skills

Responsibilities

• • Design, provision, and maintain cloud infrastructure using infrastructure-as-code practices
• • Build and operate CI/CD pipelines that support fast, safe deployments with automated rollbacks
• • Manage Kubernetes clusters, namespaces, resource quotas, and deployment strategies
• • Implement secrets management, certificate rotation, and least-privilege IAM policies
• • Set up and maintain observability: dashboards, alerting, log aggregation, and SLO tracking
• • Drive incident response processes, lead post-mortems, and implement remediation plans
• • Reduce developer toil by automating repetitive operational tasks
• • Partner with security to perform infrastructure audits and remediate findings

Requirements

• • 3+ years of hands-on cloud infrastructure experience on AWS, GCP, or Azure
• • Strong Terraform or equivalent IaC experience with production-grade module design
• • Operational experience running containerized workloads in Kubernetes in production
• • Demonstrated ability to build and maintain CI/CD pipelines for multiple services
• • Solid Linux fundamentals and ability to write maintainable shell or Python automation scripts
• • Experience designing alerting and on-call runbooks for production systems

Nice to have

• • Hands-on experience with service mesh technologies such as Istio or Linkerd
• • Knowledge of FinOps practices and cloud cost optimization tooling
• • Familiarity with GitOps workflows using ArgoCD or Flux
• • Certifications in a major cloud platform (AWS Solutions Architect, GCP Professional, etc.)

What to look for in a great DevOps Engineer

The best DevOps engineers think in systems: they anticipate failure modes, design for graceful degradation, and instrument everything so problems surface before users notice. Look for candidates who can describe a real on-call incident in detail — what they detected, how they diagnosed it, what they fixed, and what they changed afterward. Strong DevOps engineers also think about developer experience: they measure CI pipeline duration, champion fast feedback loops, and treat infrastructure as a product that internal teams depend on. Automation instinct — reaching for scripts and IaC rather than clicking through cloud consoles — is a non-negotiable signal.

Interview questions to ask a DevOps Engineer

Ask the candidate to walk through how they would design the infrastructure for a new microservice from scratch — including deployment, scaling, networking, secrets, and observability. This exercises the full breadth of the role in one scenario. Ask how they would debug a latency regression that appeared after a deployment; good answers mention canary deployments, metric diffs, and rollback procedures. Include a question about how they have reduced toil on a previous team — look for evidence of automation and systems thinking. Ask about a security incident or near-miss and how they improved controls afterward.

Where to source DevOps Engineers

Cloud provider communities (AWS re:Post, Google Cloud Community, Azure Tech Community) and Kubernetes-focused Slack workspaces surface active practitioners. Conference talks and blog posts from platforms like SRE Weekly and The Ops Community are good signals of expertise depth. LinkedIn searches combining specific IaC tools with cloud certifications help qualify candidates quickly. Internal referrals from your existing infrastructure team are high-value. For senior hires, look for engineers who have presented at KubeCon, DevOpsDays, or similar events — public contributions in this domain correlate well with practical depth.
