## About the role

Somewhere right now, an engineer has pushed a change and is watching a build run. What's doing that work is the Buildkite Agent — and that's what this team looks after. It’s the open-source agent that engineers around the world have running on their own machines, in their own clouds, in Buildkite’s own hosted agents, anywhere and everywhere Buildkite’s CI runs.

## What they're looking for

- Kubernetes & AWS — we run cloud-native infrastructure at scale
- Terraform — we manage infrastructure as code and value reusable, maintainable modules
- PostgreSQL — query optimisation, schema design, or running relational databases under load
- React & GraphQL — our frontend and API layer
- You've worked on developer tooling, CI/CD, or anything where your users are engineers with strong opinions
- You've written publicly about a problem you chased down — a post-mortem, a deep dive, a "why is this slow" investigation
