In the book Effective DevOps by Ryn Daniels and Jennifer Davis, the existence of a specific DevOps person is questioned as:
“It doesn’t usually make much sense to have a director of DevOps or some other factors that put one person in charge of DevOps. DevOps is at its core; a cultural movement and its ideas and values need to be used throughout entire organizations in order to be real.” Some other DevOps experts partly affect with this report.
They also believe that a team a key to effectiveness. But in this clarification, a team – including developers, a class assurance leader, a code release manager, and an automation architect – work under the supervision of a DevOps engineer. So, the title of a DevOps Engineer is a questionable one. Nevertheless, DevOps engineers are still in demand in the IT labor market. Some study this person to be either a system manager who knows how to code or a developer with a system administrator’s skills.
DevOps Engineer Responsibilities
The main function of a DevOps engineer is to introduce the nonstop delivery and continuous addition workflow, which needs the understanding of the stated tools and the knowledge of several programming languages. Depending on the organization, job descriptions differ. Smaller businesses look for engineers with broader skill sets and responsibilities.
For example, the job account may need product structure along with the developers. Larger companies may look for an engineer for an exact stage of the DevOps lifecycle that will work with a sure automation tool. The basic and extensively-accepted tasks of a DevOps engineer are:
- Listing specifications and documentation for the server-side features
- Management of continuous integration and continuous deployment
- CI/CD script writing
- Performance assessment and monitoring
Moreover, a DevOps engineer should be responsible for IT infrastructure keep and management, which includes hardware, software, network, storages, virtual and remote assets, and control over cloud data storing. This expertise contributes to IT infrastructure building, works with automation platforms, and cooperates with the developers, operation managers, and system administrators, facilitating processes they are responsible for.
DevOps Engineer Skillset
While this title doesn’t require a candidate to be a system administrator or a developer, this person must have experience in both fields. When hiring a DevOps engineer, pay consideration to the following features:
Tech background: A DevOps engineer must hold a step in computer science, engineering, or other related fields. Work experience must be greater than 2 years. This includes work as a developer, scheme administrator, or one of the members of a DevOps-driven team. This is an important obligation along with an understanding of all IT operations.
Automation tool experience:
The knowledge of open source keys for testing and deployment is a must for a DevOps engineer. If you use a cloud server, make sure that your candidate has experience with such tools as GitHub, Chef, Puppet, Jenkins, Ansible, Nagios, and Docker. An aspirant for this job also must have knowledge with public clouds such as Amazon AWS, Microsoft Azure, and Google Cloud.
Programming skills: An engineer not only has to know standard tools, but also must have programming experience to cover scripting and coding. Scripting skills usually entail the knowledge of Bash or PowerShell scripts, while coding skills may include Java, C#, C++, Python, PHP, Ruby, etc., or at least some of these languages.
Knowledge of database systems: At the deployment stage, an engineer everything with data processing, which requires experience with both SQL and No SQL database models.
Communication and interpersonal skills: Although a good candidate must be well-versed in tech aspects, a DevOps expert must have strong communication talents. The Person must ensure that a team function efficiently, receives and shares feedback to support continuous delivery.

When you employ a DevOps professional, you need to define the main requirements and responsibilities that this person will bring to your team. Here are several components for a complete job posting:
- Base the requests for a candidate on automation tools and programming languages you already use in development.
- Define the technical knowledge and professional experience he/she must have to insurance the requirements for this job
- Understand, whether you need a DevOps specialist to work on a particular stage of a cycle, or if he/she should be involved in every stage of a process, product development included.
- And remember that the DevOps culture is about communication and collaboration, so find a candidate who can be a team player and team leader at the same time.
