Introduction
Ask ten companies what a cloud engineer does and you'll get ten different job descriptions. One wants someone to run Kubernetes clusters. Another wants Terraform and cost reports. A third really wants a network engineer who knows AWS.
That's normal. The title covers a wide range of work, and it helps to know which version a posting means before you apply or hire.
This guide explains what a cloud engineer does day to day and how the role compares to DevOps and architecture roles. It also covers the skills employers screen for, what the pay data shows, and the realistic ways people get into the field.
TL;DR
- A cloud engineer builds, runs, and secures the infrastructure that applications use on AWS, Azure, or Google Cloud.
- The role overlaps with DevOps, SRE, and cloud architecture, so read the responsibilities in a posting, not just the title.
- Employers screen for Linux, networking, infrastructure as code, containers, scripting, and identity and access management.
- There's no BLS category for cloud engineers. The closest one, computer network architects, had a median wage of $130,390 in May 2024.
- Most people move into cloud engineering from systems administration, software development, or networking. Certifications help, but hands-on projects count for more.
What a cloud engineer does
A cloud engineer designs, builds, and maintains cloud infrastructure: networks, compute, storage, identity, and the automation that ties them together. Developers write the application.
The cloud engineer makes sure it has somewhere reliable, secure, and affordable to run.
Demand follows spending. In November 2024, Gartner forecast worldwide public cloud end-user spending of $723.4 billion in 2025, up from $595.7 billion in 2024. It also predicted that 90% of organizations will adopt a hybrid cloud approach through 2027.
Hybrid setups need engineers who understand both the cloud side and what's still running on-premises.
What a typical week looks like
The work shifts with the team, but a mid-level cloud engineer's week often includes:
- Writing or reviewing Terraform to add a new environment for a product team
- Tightening IAM policies after a security review flags broad permissions
- Debugging why a deployment fails in staging but not in development
- Adjusting autoscaling after a traffic spike pushed latency up
- Reviewing the monthly bill and shutting down idle resources
- Taking an on-call shift and writing up a short incident review
Very little of it is clicking through a console. Most of the job is code, configuration, and reading logs.
Cloud engineer vs related roles
These titles blur together in job postings. Here's how they usually differ in practice.
The last row confuses a lot of people. Our guide to hiring AWS developers and how they differ from cloud engineers covers that line in more detail.
Cloud engineer skills employers screen for
Job postings list dozens of tools, but the screening questions keep coming back to the same foundations.
Core technical skills
- Linux and operating systems. Most cloud workloads run on Linux, and troubleshooting still starts at the command line.
- Networking. Subnets, routing, DNS, load balancers, VPNs, and firewalls. Weak networking is the most common gap we see in candidates who learned cloud from certifications alone.
- Infrastructure as code. Terraform is the most widely requested tool, with CloudFormation, Bicep, and Pulumi close behind.
- Containers and orchestration. Docker, Kubernetes, and a managed service such as EKS, AKS, or GKE.
- Scripting. Python or Bash for automation, and enough Go or PowerShell to read someone else's tooling.
- Identity and access management. Least-privilege policies, roles, and federation. Misconfigured access is a common starting point for real-world breaches.
- CI/CD and monitoring. Pipelines in GitHub Actions, GitLab, or Jenkins, plus observability tools such as CloudWatch, Datadog, or Prometheus.
Depth on one cloud platform beats a surface-level tour of all three. Most employers will train a strong AWS engineer on Azure. Few will hire someone who knows a little of everything.
What changes as you get more senior
The jump from mid-level to senior is less about new tools and more about judgment. Senior engineers can explain why they chose one design over another, what it costs each month, and what happens when it fails.
Cloud engineer salary and job outlook
The U.S. Bureau of Labor Statistics doesn't track "cloud engineer" as its own occupation, so be careful with any single salary figure you see quoted. The closest official category is computer network architects.
BLS reports a median annual wage of $130,390 for computer network architects in May 2024. The lowest 10 percent earned under $79,520, and the top 10 percent earned more than $198,030.
BLS projects employment in that occupation to grow 12 percent from 2024 to 2034, much faster than the 3 percent average for all occupations.
That range is wide, and it maps roughly to seniority. In practice, these factors move cloud engineer pay the most:
- Specialization. Security and Kubernetes platform skills tend to pay more than general infrastructure work.
- Location. Pay bands often anchor to where the engineer lives, even for remote roles.
- Industry. Finance and other regulated industries pay more for engineers who can handle compliance.
- Employment type. Contract rates look higher per hour, but they don't include benefits or paid time off.
Treat salary sites as rough guides. Their numbers come from self-reported data and job titles that don't always match the actual work.
How to become a cloud engineer
Few people start as cloud engineers. Most arrive from an adjacent role, and the path depends on where you're starting.
Certifications: useful, not sufficient
Certifications help your resume get past filters, especially for contract roles where recruiters screen quickly. Common starting points include:
- AWS Certified Solutions Architect Associate, from AWS Certification
- Microsoft's Azure Administrator (AZ-104), through Microsoft Credentials
- Google's Associate Cloud Engineer
A certification shows you studied the material. It doesn't show you can fix a broken deployment at 2 a.m. Pair it with a project.
If AWS is your target, our older guide to building a career in cloud computing with AWS walks through the AWS training path in more detail.
Build one project you can explain
Pick something small and finish it. For example, a three-tier web app deployed with Terraform, running in private subnets behind a load balancer.
Give it a CI/CD pipeline, basic monitoring, and a short README that explains your design choices and monthly cost.
Interviewers will ask why you made each decision. A project you can defend line by line is worth more than five tutorials you followed.
Contract vs full-time cloud engineer jobs
A lot of cloud work is project-based: a data center migration, a move from one cloud to another, a security remediation with a deadline. Companies often fill those roles on contract rather than hiring permanently.
Our guide to IT contract staffing services explains why employers use that model.
For engineers, contract work can mean faster exposure to different environments and higher hourly rates. The trade-off is less stability and gaps between projects.
If you're weighing it, our comparison of W-2, C2C, and 1099 contract types explains how pay and employer responsibilities differ.
One pattern we see often: resumes that say "AWS experience" get fewer interviews than ones that name specific services and results. "Migrated 40 EC2 workloads to ECS with Terraform, cut compute cost by a third" gives a recruiter something to match against a requirement. "Worked on AWS cloud infrastructure" doesn't.
Final thoughts on becoming a cloud engineer
The cloud engineer title covers a lot of ground, so start by deciding which version of the job you want: infrastructure, platform, networking, or security.
Then build depth in one cloud and in the foundations that don't change between providers, such as Linux, networking, IAM, and infrastructure as code.
If you're hiring, apply the same logic in reverse. Write the posting around the work, not the title, and screen for the foundations before the tool list.

FAQs
What does a cloud engineer do?
A cloud engineer designs, builds, and maintains the infrastructure that applications run on in AWS, Azure, or Google Cloud. That includes networks, compute, storage, access controls, and the automation that manages them. Most of the work happens in code and configuration rather than in a web console.
Is a cloud engineer the same as a DevOps engineer?
Not quite, although the roles overlap and some companies use the titles interchangeably. Cloud engineers focus on the infrastructure itself, while DevOps engineers focus on how code gets built, tested, and released. On smaller teams, one person often does both.
Do you need a degree to become a cloud engineer?
Many employers list a bachelor's degree in computer science or a related field, but hands-on experience often matters more in screening. People without degrees commonly get in through systems administration or support roles, then move into cloud work. A portfolio project and a certification help make that case.
Which cloud certification should I get first?
Pick the platform most common in the jobs you want. AWS Solutions Architect Associate, Azure Administrator (AZ-104), and Google Associate Cloud Engineer are all common starting points. Build a real project on the same platform so you can talk about it in interviews.
How long does it take to become a cloud engineer?
For someone already in IT or development, a focused move into cloud often takes six months to a year of study and hands-on work. Starting from scratch usually takes longer, because networking and Linux fundamentals come first. Timelines vary with how much time you can put in each week.
Is cloud engineering a good career?
Demand is steady, because cloud spending keeps growing and most companies now run hybrid environments. The work also changes quickly, so it suits people who like learning new tools. Specializing in security, platform engineering, or cost management can open more senior roles over time.
