There’s often confusion around the question: What exactly does a DevOps Engineer do? Are they developers who also manage infrastructure? Or system engineers who’ve picked up coding? Not quite. In this article, we dive into the roles and responsibilities of a DevOps Engineer. But first, let’s clarify what DevOps actually is.
What Is DevOps?
DevOps is a software development strategy that bridges the gap between developers (Dev) and system operators (Ops). It enables organisations to rapidly launch new features and seamlessly integrate customer feedback into the product.
Key benefits include:
- Fewer software bugs
- Faster turnaround on fixes
- An end to the limitations of the traditional waterfall model
DevOps relies heavily on development, testing and deployment technologies, forming the backbone of automated CI/CD pipelines. Here are some well-known DevOps tools:
- Git & GitHub – Source code management
- Ansible – Configuration management & deployment
- Docker – Containerisation platform
- Kubernetes – Container orchestration
- Jenkins – Automation server for building CI/CD pipelines
- Selenium – Automated testing
- Puppet & Chef – Configuration management & deployment
- Splunk & ELK – Continuous monitoring
What Does a DevOps Engineer Do?
A DevOps Engineer understands the full software development lifecycle and is proficient with automation tools used to build digital pipelines (CI/CD). They’re either developers who’ve expanded into deployment and operations, or system administrators who’ve learned scripting and programming to support the development side. This dual skillset allows them to improve test planning, deployment strategies, and operational reliability.
DevOps Roles and Specialisations
The DevOps domain is broad, and several specialised roles exist within it:
- Automation Expert – Responsible for tool orchestration and process automation
- Software Developer / Tester – Develops and rigorously tests application code
- Release Manager – Oversees releases and ensures post-release stability
- Security Engineer – Monitors and enforces application and infrastructure security
- Quality Assurance – Ensures the product meets defined quality standards
- DevOps Evangelist – Drives adoption and alignment of DevOps principles across teams
