The fastest CI for AI workflows at scale nothing else survives. Leading software teams across industries have standardized on Buildkite for CI and orchestration. Backed by General Catalyst.
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

It's a critical repo to own. The team sits at an exciting intersection — deeply technical infrastructure work on one side, the fast-moving world of AI agents on the other, and our own agent sandwiched in the middle. It's the piece everything else leans on, so the details count. The people relying on you are your fellow engineers shipping their own features.
The systems you'll look after can't be paused or casually restarted. We need to constantly iterate...
