Who is a DevOps Engineer? Roles, Responsibilities and Skills

A DevOps engineer, also known as a software engineer in DevOps, has become an essential part of modern software development teams. Their main responsibility is to help organizations streamline the process of software development and deployment by automating certain repetitive tasks.

While it’s not easy to pinpoint exactly what a DevOps engineer does on any given day due to the nature of their work, there are some general practices that many follow. 

What is DevOps?

DevOps is a set of principles that encourages collaboration and communication between developers and operations teams to improve the quality of software products. By working together, these two teams can identify problems faster and more accurately than ever before.

Who is a DevOps Engineer?

A DevOps engineer is a software engineer who has the responsibility of automating the software development process, from the initial coding to the deployment of an application. These professionals are responsible for managing and maintaining all aspects of their company’s infrastructure, including servers and networks. 

As such, they must be skilled in multiple areas such as automation tools (e.g., Puppet), cloud computing services (e.g., Amazon Web Services), configuration management tools (e.g., Chef), and databases (e.g., MySQL).

DevOps Engineer’s Roles and Responsibilities

1. Automating software development

DevOps engineers are responsible for automating the software development and deployment process. They push their code to a production-ready environment, which means every time someone pushes a new change to the codebase, it’s automatically tested and deployed. 

2. Testing processes

DevOps engineers also work on automating testing processes. Their goal is to minimize manual testing by using automation tools such as Selenium or Docker containers.

3. Automating the release process

DevOps engineers take things one step further by automating the release process, too. When you’re releasing large amounts of data or apps into production environments it’s critical that you can roll back changes if something goes wrong during deployment—or worse, causes damage at scale!

4. Ensuring error-free development & deployment 

Automating this process ensures that your company can recover quickly from any errors made during release day so there aren’t any lasting effects on revenue or employee productivity.

Top Core DevOps Engineer’s Skills

2. Streamline the software process

DevOps engineers help organizations streamline software development, release, and deployment processes by automating them.

3. Help improve process stability 

They are responsible for automating the software development and deployment process. This includes automating the release process, deployment process, and test process to improve efficiency and provide more stability over time.

4. Have a deep understanding of app development & operations

DevOps engineers are required to have a thorough understanding of both application development and operations. 

5. Effective communication & technical expertise

They must communicate effectively with other developers while also working well with IT staff members who may not have as much technical expertise.

DevOps Engineers Salary

DevOps engineers are a crucial part of any team that needs to create its software. They bridge the gap between your business and its technology, making sure that the two are working together seamlessly.

DevOps engineer salaries can vary greatly depending on the company and its location. A DevOps engineer’s salary in a large city like San Francisco or New York City can be several times higher than one in a smaller city, but it’s important to remember that these cities are also more expensive to live in.

The average DevOps engineer’s salary is around $105,000 per year. However, that number varies wildly depending on factors like experience, location, and industry. 

For example, if you’re looking at companies that offer cloud computing services (like Amazon Web Services), you’ll likely find engineers with much higher salaries than those working for small businesses or startups.

In general, though, most people who work as DevOps engineers make an annual salary between $100,000 and $150,000 per year based on their experience level and educational background. 

This means that even if fewer companies are willing to pay top dollar for experienced talent than there used to be (which seems likely), there are still plenty of opportunities out there for skilled professionals who want to advance their careers in this field.
