</p></div><p><strong>Principal Software Engineer, (Libraries Platform)</strong></p> <p><strong>The role:Â </strong></p> <p>At Chainguard, we think the best platform work is invisible: the libraries just appear, the builds just work, and the CVEs quietly regret their life choices.
</p> <p>Chainguard's Libraries organization runs the secure, reliable factory that continuously builds, verifies, and serves open-source libraries to customers and internal teams across multiple ecosystems.
We're expanding that factory to new inbound ecosystems, while raising the bar on how much of the remediation and build lifecycle runs without a human in the loop.
</p> <p>As a Principal Software Engineer on the Libraries Platform team, you'll set technical direction for that expansion.
This is a strategic, cross-organizational platform role: you're not just operating the existing factory, you're deciding how it generalizes to ecosystems it wasn't originally built for, and how much of the remediation pipeline - from CVE detection through patch, rebuild, verification, and release - can become fully automated rather than engineer-mediated.
Your decisions will shape the platform's architecture for years and influence how every ecosystem team builds on top of it.
