You can work on a developer-first platform at the centre of modern software delivery. You can build the next generation of software supply chain trust and provenance infrastructure.
You will build systems that give organisations complete traceability from source code to deployed artifact. It's not just where an artifact came from, but how it was built, what went into it, and where it was used downstream.
You will build infrastructure that captures, validates, and exposes build provenance and attestation data across CI/CD pipelines and artifact ecosystems.
This role offers significant greenfield engineering work, giving you the opportunity to shape how supply chain security and artifact traceability systems are designed from the ground up.
