Outline Your Requirements First ‒ DevOps Engineers Responsibilities 

Before we move on to the DevOps engineering hiring process, let’s define who this person is and what DevOps actually means. The term is coined out of the two words ‒ “development” and “operations”. A DevOps engineer is a person who is skilled in both. It’s a versatile expert whose main function is to help different development teams improve specific parts of code and enable companies to improve their platforms based on what they already have. 

Interestingly, DevOps as a job title is kind of made up by the industry, which means that there is no step-by-step process on how to undertake this career. Whether or not someone can apply for DevOps position depends on their skills and experience with coding and working in different teams.

In short, DevOps engineer is someone who:

• Understands the Software Development Life Cycle (SDLC).
• Has a solid grasp of different automation testing tools for developing continuous integration and continuous delivery (CI/CD) pipelines.
• Can successfully manage the entire DevOps team.

So what are the main responsibilities of DevOps engineer?

Let’s take a closer look at each. 

Application and Infrastructure Planning, Testing and Development

DevOps engineer’s job is to fill the immediate business needs. In their day-to-day, DevOps look at the individual functions of the cloud environment and write code to scale them. To pull it off, a person needs to be able to write small snippets of code in several languages. They also must be skilled in testing, and big-picture planning (integrations and additions across many systems). 

Maintaining CI/CD Pipelines

DevOps engineers are responsible for building a CI/CD pipeline and making sure that all the processes, people, and tools work in sync. They can spot areas of improvement and optimize the pipeline on the go. When DevOps engineer does the job well, the team can continuously test without hampering overall speed.

Automation Implementation

Automation is the reason why organizations hire CI/CD engineers in the first place. DevOps are responsible for its implementation and their job is to boost the efficiency of both engineering and IT. Meanwhile, companies can focus on more strategic tasks. 

Ensuring Security 

DevOps engineer’s job is to support the users of the infrastructure they develop. The best way to ensure safety is to build reliable software, to begin with. Writing secure code that will be protecting the cloud against hackers and viruses is a valuable skill for a DevOps engineer. 

Ongoing Monitoring

Collecting data and understanding how to act on it effectively is crucial for every organization. That’s why DevOps engineers monitor their apps and infrastructure to detect and oversee the blind spots, observe them, and troubleshoot possible issues. 

What are the Most Important Skills for DevOps? 

Clearly, the skillset required for such professionals is far above the average. In one of the surveys conducted by DevOps Institute for their Enterprise DevOps Skills Report, C-suite executives, managers, and individual contributors were asked to rate the importance of the different skill categories for their DevOps team members.  

Take a look at the results. 

The expectations are generally pretty high, but they vary slightly based on the desired experience level.

Hiring DevOps Engineers: 3 Ways to Go 

When it comes to hiring a DevOps engineer, there are three popular options: freelance websites, recruiting agencies, and outsourcing companies. Let’s review all three in detail.

Hiring Freelancers 

Freelancer platforms like Upwork, Freelancer.com, YouTeam, Toptal are very popular when it comes to finding specialists in the IT sector. The principle behind these platforms is the same. You set up an account, create a job post, choose a freelancer (or a team of freelancers), and start a contract. 

Pros of hiring a freelancer:

• Much cheaper rates;
• Reviews from previous clients; 
• Wide range of specialists;
• Great for minor changes and short-term projects.  

Cons of hiring a freelancer:

• No guarantees;
• No formal contract signed;
• Possible language barrier;
• Different time zones;
• Management complexities causing more harm than good. 

Working with Recruiting Agencies 

Another widely used option is partnering with recruitment agencies. Here’s how it works. You let the agency know what positions you’d like to fill and they provide the recruitment services to the extent that you prefer, from identifying qualified people to conducting interviews and candidates selection. The cost of their assistance may vary based on their service model:

• Executive search ‒ the employer pays an up-front fee for assistance filling a role
• On-demand recruitment ‒ flexible support at an hourly rate
• Recruitment process outsourcing ‒ the employer entrusts the entire recruiting function to the agency.

Pros of working with recruitment agencies 

• More time for important strategic tasks; 
• Access to more qualified candidates.

Cons of working with recruitment agencies 

• The cost of recruiting;
• Lack of control;
• Indirect candidate access;
• Potential communication issues.

Hiring a DevOps Engineer through IT Companies 

This is probably the best option for projects of any size and budget. It’s less expensive than hiring in-house employees, but just as reliable.

Pros of hiring dedicated DevOps engineers through IT companies

• Cost-effectiveness; 
• Guaranteed expertise and reliability; 
• Dedicated manager for each project; 
• General team experience and quality work.

Cons of hiring DevOps engineers through IT companies

• Different time zones;
• Possible language barrier. 

Outsourcing individual experts or even the entire teams through IT companies is super convenient. They are not only qualified but have all the necessary technology in place. All you need is to share the details of your project and cooperate along the process. Sounds like a plan, isn’t it? But make no mistake, there are still some pitfalls to beware. 

The truth is, finding the right outsourcing company can be a challenge. You’ve probably heard all these urban legends about the worst outsourcing experience. However, if you take this process seriously, your project will end up in good hands. To find a reliable IT company, go beyond Google search. Places like Clutch will help you find accurate information about each team and referrals from colleagues will encourage you to make the best choice.  

Our company also provides team extension services. Here’s how it works in Relevant Software.

Next, we assemble the team, select the best-suited experts, show you CVs, invite you to perform the final interview, and smoothly integrate into your ongoing project.
