About the role
We need someone who has run a serious build system at a previous job, ideally a large Bazel monorepo, and wants to do it again here. Our codebase is a TypeScript monorepo, a Rust workspace, a protobuf layer that wires them together, and a growing pile of services and container images. CI works. It isn't hermetic, it isn't deterministic, and the cache hit rates are nowhere near where they should be. That's the work. You'll own the build and CI experience top to bottom. We're not religious about Bazel. If Buck2 fits better, or a simpler setup gets us 80% of the value, that's fine. The goal is local and CI builds that produce the same artifact, fast incremental feedback for every engineer, and a credible roadmap for what this looks like at 10x our current size.
