What does a DevOps engineer do?

A DevOps engineer builds and maintains the pipelines and automation that allow development and operations teams to release software efficiently and reliably. They also manage the infrastructure that supports software development and deployment. A typical day might involve improving a deployment pipeline or investigating a service problem, alongside writing infrastructure code.

Understanding what DevOps is and how it works provides useful context for a role that connects software development with live IT operations.

What does a DevOps engineer do?

There is rarely one fixed routine for a DevOps engineer. The role sits between development and operations, with an emphasis on making the route from code to production smoother and more dependable.

Across a typical week, an engineer might improve automated delivery or review monitoring data. Responding to incidents may also form part of the job. They frequently work with developers to remove bottlenecks from the release process, although the balance changes according to the organisation and its technology.

DevOps engineer roles and responsibilities

DevOps roles and responsibilities cover several areas of technical work, often combined within the same role.

Building and running CI/CD pipelines

Continuous integration and continuous delivery (CI/CD) pipelines automate steps involved in moving code towards production. A DevOps engineer maintains these pipelines so changes are tested consistently and move towards release efficiently.

Infrastructure as code and cloud platforms

Infrastructure as code allows infrastructure to be defined through code instead of repeated manual configuration. Engineers might use tools such as Terraform alongside a cloud platform such as AWS or Microsoft Azure, depending on their employer’s environment.

Monitoring, incidents and reliability

DevOps engineers use monitoring and observability to understand how services behave in production. They may take part in on call arrangements and respond to incidents, using what happened to improve future reliability.

Security in the pipeline

Security increasingly forms part of the delivery process rather than being left until release. DevOps engineers may therefore work with automated security checks, applying DevSecOps practices to identify vulnerabilities earlier.

Skills you need to be a DevOps engineer

DevOps engineer skills often focus on tools, but the role requires broader understanding too. Technical knowledge commonly includes Linux and Git. Scripting in Python or Bash is useful, with experience of containers and cloud environments also valuable.

Coding matters, although the level varies by role. DevOps engineers frequently write scripts or configuration code rather than spending all day developing application features. As of October 2026, the Skills England occupational standard includes scripting and coding within the duties of a DevOps engineer.

Communication and collaboration are equally relevant because DevOps depends on people working across traditional team boundaries. These and other principles matter as much as individual tools, so a DevOps Foundation certification provides a broad starting point before someone specialises in particular technologies.

How to become a DevOps engineer

Understanding what DevOps engineering is helps to explain why there is no single entry route. People often move into the field from software development or systems administration. It is typical to begin qualifications with a vendor neutral Foundation course before moving on to automation and cloud platform certifications.

The Level 4 DevOps Engineer apprenticeship offers another UK route into the profession. The current standard remains available for new starts until 17 December 2026, with a revised version taking effect from 18 December.

For career development, a certification covering broad DevOps principles is a sensible first step. A cloud platform certification may follow where a particular role requires one. This builds transferable knowledge before specialising in one technology ecosystem.

DevOps engineer salaries in the UK

Indeed reported an average UK DevOps engineer base salary of £60,333 a year on 19 October 2026, based on 1,500 reported salaries. Its published range was £38,138 to £95,444, reflecting differences in experience and location, as well as the employer.

As salary figures change over time, they are better treated as a current market indicator than a guaranteed earning level.

DevOps engineer career path

The UK Government Digital and Data Profession Capability Framework maps DevOps progression from apprentice and junior roles through to senior, lead and principal positions. As responsibilities grow, engineers move from working under supervision towards greater technical leadership and responsibility for complex delivery.

Beyond this progression, platform engineering and site reliability engineering (SRE) are possible directions. DevSecOps provides another route for people particularly interested in integrating security with software delivery.

Indeed figures indicate that some later career routes attract higher average salaries. In October 2026, its UK averages were £70,025 for platform engineers and £76,654 for site reliability engineers. Senior DevOps engineer pay was also above the general DevOps engineer average. Higher pay will always depend on the position and employer, however, so deciding on a career path should involve much more than salary considerations.

If you believe a DevOps career is the right direction for you, then DevOps courses support continued development as responsibilities change, while our DevOps Engineer learning path provides a structured route through relevant skills.

DevOps engineer vs site reliability engineer

DevOps engineering often concentrates on the systems and automation supporting software delivery. Site reliability engineering focuses more directly on keeping live services dependable and applying engineering approaches to operational problems.

Neither is inherently a better career for UK job seekers. DevOps may appeal more to someone interested in delivery pipelines and infrastructure automation. SRE may suit someone drawn to production reliability and incident response.
