About this role
Senior DevOps Engineer, CI/CD Platform (Developer Experience)
Hey there, Kubernetes people!
Why this role exists
Hundreds of developers push to a large Ruby on Rails monorepo, and every push lands on a runner fleet that the Developer Experience team builds, runs and keeps fast.
That fleet is self-hosted Kubernetes on bare metal in European datacentres, in the low hundreds of machines, running ephemeral GitHub Actions runners that peak above a thousand concurrent pods. We own all of it: the hardware, the clusters, the runner images, the caches and the delivery pipelines on top. We add nodes by hand rather than letting an autoscaler do it, so capacity planning is genuinely part of the job.
The leverage is unusual. Shave a minute off the average build and every engineer in the company gets that minute back, several times a day.
