Software Engineer (Libraries Platform)
Overview
Chainguard is the trusted source for open source, delivering hardened, secure, and production-ready builds of open source software.
Job Description
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. Chainguardās Libraries organization is building the secure, reliable factory that continuously builds, verifies, and serves openāsource libraries to our customers and internal teams across multiple ecosystems.
Responsibilities
- - 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 ā including AI-assisted patching ā 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 postāincident 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 handsāon debugging, helping to ācode cultureā into how we build and run our libraries platform.
Required Skills
- - 3-5 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) 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, cloudānative 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.
- - An ownership mindset: you set technical direction, own critical outcomes, and are comfortable in an early, highāimpact area where engineers help shape both the roadmap and the culture.
Benefits
- - Flexible & Remote-First Culture: Work remotely with team meetup opportunities, bi-annual destination summits, and a monthly stipend for coworking spaces, phone and internet costs.
- - Our Approach to Equity: Receive stock options upon hire and promotion. Plus, you can participate in secondary offerings and have 10 years to exercise your options.
- - 100% Covered Health Insurance: We cover 100% of your health, vision and dental insurance premiums for you and your dependents.
- - ā Flexible Time Off: Take the time you need ā to do our best work, we need to recharge and reset.
- - 18 Weeks Paid Parental Leave: We offer 18 weeks for birthing parents and 12 weeks for non-birthing parents, with the option to use it all at once or throughout your child's first year.
About the company
Chainguard believes engineering teams should move at the speed of innovation with confidence that every line of code is secure. The company protects open source software from what can go wrong, enabling teams to focus on building what matters. Securing the open source supply chain is Chainguardās mission. Teams are often told they must choose between speed, security, and scalability when building on open sourceāachieving all three is seen as impossible. Chainguardās co-founders rejected that trade-off. With decades of experience building foundational projects like Kubernetes, Sigstore, and Distroless, they recognized that these priorities are not in conflict but part of the same system.
