DevOps vs SRE vs Platform Engineer: Roles, Skills and Salary Compared

DevOps engineers, Site Reliability Engineers (SREs) and Platform Engineers all use Linux, CI/CD, containers, Kubernetes, cloud and infrastructure as code. What differs is what they are measured on.

A DevOps engineer automates the path from commit to production: CI/CD pipelines, container builds, Kubernetes deployments, Terraform for infrastructure, and the release process. It is the most common entry role and the one most freshers and career switchers start with.

Site Reliability Engineering started at Google as "what happens when you ask a software engineer to run operations". SREs define SLIs and SLOs, run on-call, lead incident response and post-mortems, and write software to remove repetitive operational work (toil). Strong observability skills, Prometheus, Grafana, logging and tracing, matter more here than anywhere else.

Platform engineers build the internal developer platform: self-service templates, golden paths, shared Kubernetes clusters, CI/CD building blocks and developer portals such as Backstage. Their customers are the company's own developers.

Starting out or switching careers? Aim for DevOps engineer. It has the most openings and teaches the foundations the other two build on.

Enjoy debugging production and owning reliability? Grow into SRE after one or two years.

Enjoy building tools and APIs for other engineers? Grow into platform engineering.

All three share the same foundation, which is why our DevOps roadmap is the right starting point whichever you choose. Salaries are broken down further in the DevOps engineer salary guide.
