DevOps is no magic, but it can definitely look like it from the outside. In today’s corporate world, workers in innovative fields are generating new roles for themselves. The role of the DevOps Engineer is one instance of such.

There’s a lot of misconception regarding who is a DevOps Engineer – are they the person who writes the code? Or are they responsible for the work of a system engineer? 

Well! Not exactly. Through this post, I shall guide you through the roles and responsibilities of a DevOps Engineer. But first, let us know what DevOps is.

What is DevOps?

It is a combination of Development and Operations. DevOps is the blend of cultural philosophies, tools, and practices that increase an organization’s ability to deliver services and applications quickly. It helps them upgrade products faster than organizations using traditional software development and infrastructure management procedures.

This speed facilitates organizations to serve their customers better and compete more efficiently in the market.

DevOps culture is introduced to improve collaboration, communication, and agile relations between the operations and software development teams. It bridges the gap between the development and operations teams.

Sometimes, the two teams work as one team where the engineers work through the entire application lifecycle, from development to test and deployment to operations. They develop a set of skills required for both software development and operations.

Simply put, DevOps is a set of practices that combine Software Development (Dev) and IT operations (Ops), which intend to shorten the systems development life cycle and provide continuous delivery with high software quality.

Unlike popular opinions, DevOps is not:

• a combination of the Development and Operations team.
• a tool or a product.
• a separate team.
• automation.

However, it is a process that includes continuous:

• Integration
• Development
• Testing
• Deployment
• Monitoring

What is a DevOps Engineer?

A DevOps engineer is a professional who bridges software developers, system operators, and other production IT staff and supervises code releases and deployments. They require a rich set of hard and soft skills to bypass the communication barrier between software development, testing, and IT operations teams by fostering a collaborative environment.

The primary goal of DevOps engineers is to shorten the development cycle and enable releasing updates quickly.

A DevOps Engineer is truly a revival of the cloud infrastructure IT services. It is often strenuous to understand their role because they are the product of the dynamic workforce that has not yet finished evolving.

These professionals come from a multitude of IT backgrounds and begin the role in different places in their careers. Generally, their role is not as easy as it appears. It requires looking into seamless team integration and successfully and continuously deploying the code.

Furthermore, the DevOps approach to software development requires recurring, incremental changes, and engineers seldom code from scratch. However, they must understand the fundamentals of software development languages and thoroughly use the development tools to make a new code or update the existing one.

Understanding the Role of a DevOps Engineer

DevOps Engineers work in conjunction with the development team and help in coding and scripting to connect the elements of the application under development, such as software development kits (SDKs) or libraries. Further, they help integrate other components, such as messaging tools or SQL data management, to run the software release with operating systems and production infrastructure.

They should be able to manage the IT infrastructure in accordance with the supported software code dedicated to multi-tenant or hybrid cloud environments. There’s a need to have a facility for required resources, procuring the appropriate deployment model, validating the release, and monitoring performance.

Further, DevOps engineers could either be the system administrators who have moved into the coding domain or the developers who have moved into operations. Either way, it is a cross-function role that sees a huge upward trajectory in how software is developed and deployed in object-critical applications.

It isn’t rare for DevOps to be called to mentor software developers and architecture teams within an organization to educate them about how to create easily scalable software. They also work with the security teams and IT to ensure quality releases. Some DevOps teams include DevSecOps, which bids DevOps principles to drive security measures.

The DevOps Engineer is a significant IT team member who works with an internal customer. This includes software and application developers, QC personnel, project managers, and stakeholders, usually from the same organization.

They rarely work with end-users but keep a “customer first” mindset to comply with the needs of their internal clients. They are customer-service-oriented team players who can arise from a number of different work and educational backgrounds. Still, through their vivid experience, they have developed the right skill set to move into DevOps.

Responsibilities of a DevOps Engineer

Typically, the role of a DevOps engineer is as follows:

• Work with a variety of open-source tools and technologies for managing source codes.
• Deploying multiple automation tools to perfection.
• Continuous iteration of software development and testing.
• Connect to business and technical goals with alacrity.
• Analyze code and communicate descriptive reviews to development teams to ensure a marked improvement in applications and on-time completion of projects.
• Design, develop, and implement software integrations based on user reviews.
• Apply cloud (AWS, GCP, Azure) computing skills to deploy upgrades and fixes.
• Troubleshoot production problems and coordinate with the development team to streamline code deployment.
• Conduct systems tests for performance, availability, and security.
• Collaborate with team members to improve the company’s engineering tools, data security, systems, and procedures.
• Optimize the company’s computing architecture.
• Troubleshooting documentation.
• Implement automation tools and frameworks (CI/CD pipelines).
• Develop and maintain design.
• Understand the needs and difficulties of a client across development and operations.
• Formulate solutions that support business, technical strategies, and the organization’s goals.
• Develop solutions encompassing technology, process, and people for continuous delivery, build and release management, infrastructure strategy & operations, and a basic understanding of networking and security.
• Implement and recommend solutions.
• Expertise and knowledge in current and emerging processes, techniques, and tools.
• Build the DevOps practice within ThoughtWorks and drive our thought leadership externally.
• Timely identification and resolution of problems.
• Design, develop, and maintain the CI/CD tools and infrastructure to deliver Horizon Cloud Service.
