Quick summary
- A DevOps engineer makes the path from code to production fast, reliable and safe - through CI/CD, infrastructure-as-code, observability and cloud operations.
- The skills that matter are practical: pipelines, IaC (Terraform), containers and Kubernetes, cloud platforms, monitoring, and a strong security mindset.
- A dedicated or staff-augmented model gets you pre-vetted DevOps talent quickly - valuable, since strong DevOps engineers are scarce and expensive to recruit permanently.
A strong DevOps engineer is a force multiplier: they make every other engineer ship faster and the whole team sleep better, by turning deployment, infrastructure and monitoring from constant firefighting into something boring and reliable. This guide covers what DevOps engineers actually do, the skills that matter, what it costs, and the interview questions that reveal genuine ability.
What a DevOps engineer actually does
- Builds and maintains CI/CD pipelines so code ships safely and often.
- Manages infrastructure as code (e.g. Terraform) for repeatable, version-controlled environments.
- Runs containers and orchestration (Docker, Kubernetes) where it fits.
- Sets up monitoring, logging and alerting so problems surface early.
- Hardens security and manages secrets, access and compliance.
- Optimises cloud cost and reliability across environments.
The skills that matter
Beyond tool names, look for practical, hands-on capability:
| Area | What good looks like |
|---|---|
| CI/CD | Reliable, automated pipelines from commit to production |
| Infrastructure as code | Terraform (or similar) for repeatable environments |
| Cloud | Real depth in Azure, AWS or GCP |
| Containers | Docker and Kubernetes used appropriately, not by default |
| Observability & security | Monitoring, alerting, secrets and access done right |
Key takeaway: Beware tool-list resumes. A great DevOps engineer reaches for the simplest thing that works - not Kubernetes for every problem.
Interview questions that reveal ability
- Walk me through your ideal CI/CD pipeline - and where you'd keep it simple.
- How do you manage infrastructure so environments are repeatable and recoverable?
- When would you not use Kubernetes?
- How do you approach monitoring and on-call so issues surface before users notice?
- How do you handle secrets, access and security in a cloud environment?
- Tell me about an outage you handled - and what you changed afterwards.
What it costs and how to hire
Strong DevOps engineers are scarce and expensive to recruit permanently, and rates vary by seniority and location - senior offshore talent costs a fraction of onshore for comparable skill. Because the need often varies (intense during a migration, steadier afterwards), a dedicated or staff-augmented model is frequently the best fit: pre-vetted DevOps expertise quickly, scaled to your actual need, without a permanent hire you struggle to keep busy.

Conclusion
A good DevOps engineer turns deployment and infrastructure from a source of stress into something dependable. Hire for practical CI/CD, infrastructure-as-code, cloud and observability skills - and the judgement to keep things simple - over a long tool list. Given how scarce the talent is, a dedicated or staff-augmented model is often the smartest way to get it.
