Who is DevOps engineer?
DevOps engineers are a group of influential individuals who encapsulates depth of knowledge and years of hands-on experience around a wide variety of open source technologies and tools. They come with core attributes which involve an ability to code and script, data management skills as well as a strong focus on business outcomes. They are rightly called “Special Forces” who hold core attributes around collaboration, open communication and reaching across functional borders.
DevOps engineer always shows interest and comfort working with frequent, incremental code testing and deployment. With a strong grasp of automation tools, these individuals are expected to move the business quicker and forward, at the same time giving a stronger technology advantage. In nutshell, a DevOps engineer must have a solid interest in scripting and coding, skill in taking care of deployment automation, framework computerization and capacity to deal with the version control system.
Qualities of a DevOps Engineer
Collated below are the characteristics/attributes of the DevOps Engineer.
What exactly DevOps Engineer do?
DevOps is not a way to get developers doing operational tasks so that you can get rid of the operations team and vice versa. Rather it is a way of working that encourages the Development and Operations teams to work together in a highly collaborative way towards the same goal. In nutshell, DevOps integrates developers and operations team to improve collaboration and productivity.
The main goal of DevOps is not only to increase the product’s quality to a greater extent but also to increase the collaboration of Dev and Ops team as well so that the workflow within the organization becomes smoother & efficient at the same time.
DevOps Engineer has an end-to-end responsibility of the Application (Software) right from gathering the requirement to development, to testing, to infrastructure deployment, to application deployment and finally monitoring & gathering feedback from the end users, then again implementing the changes. These engineers spend more time researching new technologies that will improve efficiency and effectiveness.They Implement highly scalable applications and integrate infrastructure builds with application deployment processes.
Let us spend some time in understanding the list of most important DevOps Engineers’ roles and responsibilities.
1) The first and foremost critical role of a DevOps Engineer is to be an effective communicator i.e Soft Skills. A DevOps Engineer is required to be a bridge between the silos and bring different teams together to work towards a common goal. Hence, you can think of DevOps Engineers as “IT Project Managers”. They typically work on a DevOps team with other professionals in a similar role, each managing their own piece of the infrastructure puzzle.
2) The second critical role of DevOps Engineer is to be Expert Collaborators. This is because their role requires them to build upon the work of their counterparts on the development and IT teams to scale cloud programs, create workflow processes, assign tenants and more.
3) Thirdly, they can be rightly called “Mentors” as they spend most of the time in mentoring and educating software developers and architecture teams within an organization on how to create software that is easily scalable. They also collaborate with IT and security teams to ensure quality releases.
Next, they need to be a “customer-service oriented” individuals. The DevOps Engineer is a customer-service oriented, team player who can emerge from a number of different work and educational backgrounds, but through their experience has developed the right skillset to move into DevOps.
The DevOps Engineer is an important IT team member because they work with an internal customer. This includes QC personnel, software and application developers, project managers and project stakeholders usually from within the same organization. Even though they rarely work with external customers or end-users, but they keep close eye on a “customer first” mindset to satisfy the needs of their internal clients.
Not to miss out, DevOps engineer holds broad knowledge and experience with Infrastructure automation tools. A key element of DevOps is automation. A lot of the manual tasks performed by the more traditional system administrator and engineering roles can be automated by using scripting languages like Python, Ruby, Bash, Shell, Node.js. This ensures a consistent performance of manual tasks by removing the human component and allowing teams to spend the saved time on more of the broader goals of the team and company.
Hence, a DevOps engineer must possess the ability to implement automation technologies and tools at any level, from requirements to development to testing and operations.

Skills that DevOps engineer need to have
If you’re aiming to land a job as a DevOps engineer in 2018, it’s not only about having a deep specialized skill but understanding how a variety of technologies and skills come together.One of the things that makes DevOps both challenging to break into is that you need to be able to write code, and also to work across and integrate different systems and applications. Based on my experience, I have finalized on the list of top 5 skill sets which you might require to be a successful DevOps engineer:
#1 - SysAdmin with Virtualization Experience
Deployment is a major requirement in devops role and ops engineer are good at that , All is needed is a deployments automation engine(chef ,puppet ,ansible) knowledge and its use-cases implementations . Nowadays , most of public clouds are running multiple flavors of virtualization so a must have 3 – 5 years of virtualization experience with VMware, KVM, Xen, Hyper-V is required along .
#2 - Solution Architect Role
Along with deployments or virtualization experience, understanding and implementation of all the hardware technologies in breadth is a must like storage and networking. Nowadays there is a very high-demand for people who can design a solution that scales and performs with high availability and uptime with minimal amount of resources to feed on (Max utilization) .
#3 - A Passionate Programmer/API Expertise
#4 - Integration Skillset around CI-CD tool
A DevOps engineer should be able to use all his expertise to integrate all the open source tools and technique to create an environment that is fully automated and integrated. The goal should be for zero manual intervention from source code management to deployment state, i.e. Continuous Integration, Continuous Delivery and Continuous Deployment.
#5 - Bigger Picture & Customer Focus
While the strong focus on coding chops makes software engineering a natural path to a career in DevOps, the challenge for candidates who are coming from this world is that they need to be able to prove that they can look outside their immediate team and project. DevOps engineers are responsible for facilitating collaboration and communication between the Development and IT teams within an organization, so to succeed in an interview, you’ll need to be able to demonstrate your understanding of how disparate parts of the technical organization fit and work together.
