Chainguard is the trusted source for open source. By delivering hardened, secure, and production-ready builds of all the open source software engineers and AI agents rely on, Chainguard helps organizations build faster, stay compliant, and eliminate risk.  Our customers include Fortune 500 enterprises and global industry leaders, including Anduril, Canva, Fortinet, Hewlett Packard Enterprise, OpenAI, Snap Inc., and Snowflake. Chainguard is venture-backed by leading investors, including Amplify, IVP, Kleiner Perkins, Lightspeed Venture Partners, Mantis VC, Redpoint Ventures, Sequoia Capital, and Spark Capital. The role:  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. Chainguard’s Libraries organization is building the secure, reliable factory that continuously builds, verifies, and serves open‑source libraries to our customers and internal teams across multiple ecosystems. You’ll join as a Senior Software Engineer on the Libraries Platform team, leading the architecture and implementation of the platform that powers this factory: the services, APIs, and automation that make our libraries reproducible, trustworthy, and always up to date. This is an infrastructure‑centric, platform role. You’ll work on shared services, build and packaging pipelines, and a package index that serves external customers and internal ecosystem teams. You’ll help invent and operate the platform that: Serves packages to customers at scale Automates CVE remediation and verification workflows Powers AI‑driven package builds Provides shared services across language ecosystems (Java, JavaScript, Python/AI/ML and beyond) What you’ll do: Lead the design and implementation of core components of the Libraries Platform including the services, pipelines, and package index that power secure, reproducible build, test, and distribution workflows for libraries across multiple ecosystems (Java, JavaScript, Python/AI/ML). Design and maintain automation for artifact creation, updates, and verification, including vulnerability scanning, remediation workflows, SBOM and provenance generation, and policy enforcement across our library catalog. Build toward novel patch generation. Develop and validate automation that generates security fixes — including AI-assisted patching — rather than only applying upstream patches, with the testing and verification needed to trust the result. Build and operate shared platform services such as package indexes, registry mirrors, metadata services, and orchestration tooling that serve both external customers and internal ecosystem teams. Develop internal developer tools and CLIs (often in Go) that improve how we build, test, and ship libraries at scale, including integration with build systems and CI/CD for multiple ecosystems. Drive reliability, scalability, and observability for the Libraries platform: define SLOs, build monitoring and alerting, and lead incident response and post‑incident improvements. Solve complex dependency and build issues in production environments, from toolchain and compiler problems to CI/CD flakiness and registry/package index edge cases. Partner closely with ecosystem teams (Java, JavaScript, Python/AI/ML), Platform, Delivery, Sustaining, and Security to ensure the platform meets reliability, security, and product requirements. Mentor and unblock other engineers through design reviews, documentation, and hands‑on debugging, helping to “code culture” into how we build and run our libraries platform. What we’re looking for: 5+ years designing, building, and operating infrastructure for language ecosystems or developer platforms, such as build systems, package registries, or CI/CD for widely used libraries or services.  Strong proficiency in Go (Golang) o
