The role
Chainguard’s Libraries organization builds a secure, reliable factory that continuously builds, verifies, and serves open-source libraries to customers and internal teams across multiple ecosystems. You’ll join as a Staff 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
What you’ll do
- 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 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.
- 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
- 8+ 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) or strong readiness to ramp quickly.
- Proven track record building and owning developer tooling and automation (plugins, CLIs, code generators, or custom pipelines) that improve how engineers build and ship software at scale.
- Strong background in CI/CD, cloud-native infrastructure, and IaC: containers (Docker/OCI, Kubernetes), public cloud (GCP, AWS, Azure), and tools like Terraform and GitHub Actions/Argo/Tekton (or equivalents).
- Demonstrated ability to debug and resolve complex toolchain, compiler, packaging, and infrastructure failures in production, and to drive those issues to root cause and lasting fixes.
- Comfortable working across SRE / platform / DevOps style responsibilities, including reliability, observability, and performance tuning for critical services and pipelines.
- Excellent communication in a remote, distributed environment, with a bias toward documentation, clarity, and collaboration across product, infra, and security teams.
- A staff-level ownership mindset: you set technical direction, own critical outcomes, and are comfortable in an early, high-impact area where engineers help shape both the roadmap and the culture.
Nice to have
- Experience with software supply chain security: SLSA, SBOMs, sigstore, provenance, attestations, or secure-by-default packaging practices.
- Background with Linux distributions, packaging, and reproducible build systems (e.g., Alpine, Wolfi, Debian Bazel, CMake, Ninja).
- Familiarity with AI/ML packaging and infrastructure building native Python libraries and ML frameworks (e.g., PyTorch, TensorFlow) and deploying them in cloud/Kubernetes environments.
- Prior experience in SRE, platform engineering, or DevOps roles where you owned infrastructure for developer productivity, CI/CD, or large language-ecosystem codebases.
