Senior Engineer - Agents

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.

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.
