Guide to Hire DevOps Engineers

Who is a DevOps Engineer – and how to hire the right one?


In recent times, DevOps has emerged as an effective framework where software companies can deliver their applications quickly to their customers. As a framework, DevOps integrates application development with operations, thus optimizing the workflow between them.

As more companies adopt the DevOps framework, a DevOps Engineer can add value to their operations with their expertise. If you are looking to hire DevOps Engineers, here’s everything you need to know about what a DevOps engineer does—and how to hire the right one!

Who is a DevOps Engineer?

A DevOps Engineer is a technical expert who can introduce DevOps processes, methodologies, and tools into any software development lifecycle (SDLC).

Additionally, they also need to possess interpersonal skills to coordinate work between these two teams.

Next, let's see when organizations need to hire a DevOps Engineer.

When You May Need a DevOps Engineer

Typically, companies may hire a DevOps Engineer when they want to streamline their application development and delivery process. In the competitive of business applications, product companies want to stay ahead by releasing high-quality applications at short intervals. As they operate across multiple development environments, companies need to think about factors like productivity and scalability. This means automating manual processes that are related to product development, building, deployment, and testing. 

A DevOps Engineer can benefit your company in the following ways:

  • Implement automated processes that enable faster product development at lower costs.
