Software Engineer, Chainguard

• 3+ 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
• 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
• 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)
• 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
• If your experience is close but doesn't fulfill all requirements, please apply. We're building the best team in technology and are focused on hiring "Chainguardians" with unique backgrounds, perspectives, and experiences

Desirable

• 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 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
• Powers AI‑driven package builds
• Provides shared services across language ecosystems (Java, JavaScript, Python/AI/ML and beyond)
• Contribute to the design and implementation of the Libraries Platform: spanning 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 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
• Contribute to design reviews, documentation, and hands-on debugging to help teammates move past blockers and reinforce our engineering culture in how we build and run the libraries platform
