DevOps
The practice of automating how software is tested, deployed, and run, so a team can ship safely and often.
What it tells you about a developer
Good DevOps engineers are force multipliers, because their work speeds up every other developer at the company. The skill set is in structural shortage, so expect outbound-heavy searches and compensation pressure. On GitHub the tell is repositories full of workflow and configuration files.
DevOps merged two jobs that used to be separate: writing software and operating it. A DevOps engineer builds the pipelines, cloud configuration, and monitoring that let product developers deploy their own code. The title overlaps heavily with SRE and platform engineering, and the tools are the infrastructure tools: Docker, Kubernetes, Terraform, GitHub Actions.
