What Is a DevOps Engineer? Job Responsibilities, Salary, Skills & Career Development [2025 Complete Guide]

"DevOps engineers make over NT$1 million annually, and salaries are still rising."

You've probably seen this statement many times on PTT or various tech communities.

But what exactly do DevOps engineers do? What skills are required? Is it really that easy to find a job?

If you're considering a career transition or want to understand what this role really looks like, this article will give you complete answers.

What Is a DevOps Engineer?

The Role of a DevOps Engineer

A DevOps engineer is the bridge connecting development teams and operations teams.

Traditionally, developers would write code and throw it to operations, who would be responsible for deployment and maintenance. The two sides worked separately, blaming each other when problems arose.

DevOps engineers emerged to break down this barrier.

This role requires:

  • Understanding development processes and code
  • Familiarity with system architecture and infrastructure
  • Building automation processes to make software delivery faster and more stable

Simply put, a DevOps engineer uses engineering methods to solve operations problems.

To understand the complete DevOps concept, refer to What Is DevOps? 2025 Complete Guide.

DevOps vs Traditional SysAdmin vs SRE

These three roles are often confused. Let's clarify the differences:

RoleCore ResponsibilityTechnical FocusMindset
Traditional SysAdminMaintain server operationsManual operations, scriptsStability first
DevOps EngineerBuild automated delivery processesCI/CD, IaC, containersAutomation first
SREEnsure system reliabilitySLO, Error BudgetReliability first

Traditional SysAdmin (System Administrator):

  • Mainly manages servers manually
  • Work includes installing software, setting permissions, backing up data
  • Skills lean toward specific operating systems (Linux, Windows Server)

DevOps Engineer:

  • Emphasizes automation and code-based infrastructure
  • Builds CI/CD pipelines, manages cloud infrastructure
  • Requires programming ability (Python, Go, Bash)

SRE (Site Reliability Engineer):

  • A role proposed by Google, implementing DevOps principles
  • More focused on system reliability and performance
  • Uses quantifiable metrics like SLO and Error Budget

For deeper understanding of the differences, refer to DevOps vs SRE vs DevSecOps Complete Comparison.

FAQ

What's the Difference Between DevOps Engineer and Backend Engineer?

Backend Engineer focuses on:

  • Developing application features
  • Designing APIs
  • Database operations
  • Business logic implementation

DevOps Engineer focuses on:

  • Building automated delivery processes
  • Managing infrastructure
  • Ensuring stable system operation
  • Optimizing developer experience

The two have overlap but different focus areas.

Can I Apply for DevOps Without Relevant Experience?

Yes, but it's recommended to:

  • Accumulate personal project experience first
  • Get cloud or Kubernetes certifications
  • Start from junior positions
  • Or transition from within your current job

Do DevOps Engineers Need to Be On-Call?

Mostly yes.

On-call rotation is a common work pattern for DevOps. When systems have issues, you need to be on standby to handle them. However, good teams will:

  • Have reasonable rotation arrangements
  • Provide on-call allowances
  • Continuously improve system stability to reduce alerts

Will DevOps Be Replaced by AI?

Not in the short term.

AI can certainly help with:

  • Automating repetitive work
  • Anomaly detection and alerting
  • Code review suggestions

But the systematic thinking, problem-solving, and cross-team collaboration abilities that DevOps requires cannot be replaced by AI currently.

On the contrary, DevOps engineers who can use AI tools will be more competitive.

Is DevOps Suitable for Women?

Absolutely!

DevOps requires technical ability and collaborative spirit, regardless of gender. The industry currently has a lower proportion of women, but this is changing. Many companies are actively promoting diverse and inclusive team cultures.


Conclusion

DevOps engineer is a challenging and opportunity-filled position.

It requires you to:

  • Continuously learn new technologies
  • Cross the boundary between development and operations
  • Solve problems with an automation mindset
  • Collaborate closely with different teams

But it also offers:

  • Competitive salary
  • Diverse career development paths
  • Direct impact on product delivery
  • Ever-growing market demand

If you enjoy solving problems, appreciate the sense of accomplishment from automation, and are willing to continuously learn, DevOps might be a great career choice for you.
