THE ROLE, IN A NUTSHELL Chainguard delivers the industry's most secure container images: minimal, zero-CVE, rebuilt daily from source. This role sits on our Package and Image Automation team, part of Sustaining Automation — the group that owns the automation underpinning our entire image factory. As we scale the number of ecosystems and images we support, this team builds and maintains the systems that keep packages and images current, tested, and building cleanly with as little manual intervention as possible. As a Senior Engineer, you'll be a hands-on contributor to a small, focused squad, designing systems and building AI-powered tooling that raise the reliability and speed of our automation.
