How to Hire a DevOps Engineer
Learn how to hire a DevOps engineer with our complete guide covering infrastructure skills, CI/CD expertise, and cloud platform evaluation.
The short answer
Hiring a DevOps Engineer comes down to verifying proficiency with cloud platforms such as aws, google cloud, or microsoft azure, experience with containerization technologies like docker and orchestration with kubernetes and infrastructure as code skills using terraform, cloudformation, or pulumi before you commit interview time. The process below runs 4 stages, screens on evidence rather than résumé claims, and scores every candidate against the same criteria.
- Watch for: Relies heavily on manual processes and shows resistance to automation
- Watch for: Cannot explain infrastructure decisions in terms of business impact or cost tradeoffs
- Score on: Depth of cloud platform expertise and infrastructure design skills
- Score on: Automation mindset demonstrated through CI/CD and IaC proficiency

DevOps engineers bridge the gap between software development and IT operations, enabling teams to deliver software faster and more reliably. As companies accelerate their release cycles and adopt cloud-native architectures, skilled DevOps professionals have become indispensable. Hiring the right DevOps engineer can dramatically improve deployment frequency, system reliability, and team productivity.
Why this role matters
DevOps engineers directly impact business velocity by automating deployment pipelines, reducing downtime, and enabling rapid iteration. Their work ensures that infrastructure scales efficiently with business growth and that incidents are detected and resolved quickly. Without strong DevOps practices, engineering teams waste significant time on manual processes and firefighting production issues.
Where to find candidates
- LinkedIn with targeted searches for DevOps, SRE, and platform engineering titles
- GitHub and GitLab profiles showcasing infrastructure-as-code and automation projects
- DevOps-focused communities like DevOps Subreddit, HashiCorp forums, and CNCF Slack
- Cloud provider certification directories for AWS, GCP, and Azure certified professionals
- Tech conferences like KubeCon, DevOpsDays, and local infrastructure meetups
Skills to look for
Red flags
- Relies heavily on manual processes and shows resistance to automation
- Cannot explain infrastructure decisions in terms of business impact or cost tradeoffs
- Lacks experience with version control for infrastructure configurations
- No familiarity with monitoring, alerting, or incident response procedures
- Siloed mindset that treats operations as separate from development concerns
The interview process
- 1
Technical Screening Call
A 45-minute call with a senior engineer to evaluate foundational knowledge of Linux systems, networking, and cloud services. Include scenario-based questions about handling deployments, scaling infrastructure, and responding to production incidents.
- 2
Infrastructure Design Exercise
Ask the candidate to design a production-ready deployment architecture for a given application, including load balancing, auto-scaling, database management, and disaster recovery. Evaluate their ability to make cost-effective, scalable, and secure design choices.
- 3
Hands-On Technical Assessment
Provide a practical exercise such as writing a Terraform module, building a CI/CD pipeline, or debugging a container orchestration issue. Assess their ability to write clean infrastructure code, troubleshoot effectively, and document their work.
- 4
Collaboration and Culture Interview
Conduct a behavioral interview focusing on cross-team collaboration, incident management experiences, and their approach to balancing speed with reliability. Include questions about mentoring, knowledge sharing, and handling pressure during outages.

Common questions
What is the difference between DevOps and SRE?
DevOps is a broad cultural and technical approach to unifying development and operations, while Site Reliability Engineering is a specific discipline that applies software engineering principles to infrastructure and operations problems. SRE roles tend to be more focused on reliability, SLOs, and error budgets.
Which cloud certifications should I look for in a DevOps engineer?
AWS Solutions Architect, AWS DevOps Engineer Professional, Google Cloud Professional DevOps Engineer, and Azure DevOps Engineer Expert are the most valued certifications. However, practical experience and demonstrated skills should weigh more heavily than certifications alone.
How do I assess a DevOps candidate's automation skills?
Ask them to walk through infrastructure they have automated in the past, review their public repositories for IaC examples, and include a practical exercise where they write automation code. The quality and maintainability of their code matters as much as whether it works.
