Imagine a Java ecosystem where builds are reproducible, dependencies are trustworthy, and the factory just hums. We’re hiring a Staff Software Engineer for Chainguard’s Libraries organization, focused on the Java ecosystem. You’ll contribute to the technical direction for our Java libraries factory: secure, reliable, automated build and packaging pipelines that produce high-quality Java artifacts for customers and internal teams. This is an infrastructure-focused role. You’ll build systems and tooling used by many engineers, directly supporting Chainguard Libraries, one of our major product lines.

What You’ll Do

  • Own architecture and direction for Java ecosystem infrastructure, enabling secure, reproducible build, test, and distribution workflows for Java libraries and SDKs.
  • Design and maintain automation for building, updating, validating, and publishing Java artifacts, including vulnerability scanning, remediation, SBOMs, and provenance.
  • Build internal developer tools (Gradle/Maven plugins, CLIs, code generators) that improve how we build and maintain Java packages at scale.
  • Integrate deeply with Gradle and Maven and artifact repositories, solving complex dependency and module-resolution issues in large codebases and mono-repos.
  • Collaborate with product and engineering leadership to shape the Java libraries roadmap and deliver on key business outcomes for Chainguard Libraries.
  • Mentor and unblock other engineers through design reviews, documentation, and hands-on debugging of build and infrastructure issues.
  • Partner with Platform, Delivery, Sustaining, and Security to ensure Java pipelines and services meet reliability and security expectations.

Core Experience

  • 8+ years working in Java or similar ecosystems on build systems, packaging, or developer tooling, ideally on platform/infra or ecosystem teams.
  • Proven experience building and owning Gradle/Maven plugins, CI/CD automation, or internal frameworks/tools for Java libraries or services.
  • Deep familiarity with Gradle and Maven for building and packaging libraries (multi-module builds, dependency graphs/BOMs, publishing to registries).
  • Strong background in orchestrating large codebases or mono-repos and fixing dependency and build failures in production environments.
  • Comfortable working with infrastructure code and tooling (e.g., Go-based systems, Terraform, CI/CD), alongside deep Java expertise.
  • Demonstrated ability to debug toolchain, compiler, and packaging issues at scale and drive them to resolution.
  • Experience with cloud-native environments: containers (Docker/OCI, Kubernetes), public cloud (GCP, AWS, or Azure), and modern CI/CD systems (e.g., GitHub Actions, Argo, Tekton, or similar).
  • Excellent communication in a remote, distributed setup.
  • Comfortable working across product, infra, and security, and mentoring peers at senior levels.
  • A staff-level ownership mindset: you define direction, own critical outcomes, and thrive in an early, high-impact area where engineers help set the roadmap.

Nice to have

  • Open source contributions in the Java ecosystem (libraries, build tools, packaging, or related infrastructure).
  • Experience building and distributing widely used libraries, SDKs, or runtimes.
  • Familiarity with software supply chain security: SLSA, SBOMs, sigstore, provenance, attestations.
  • Prior work in SRE, platform engineering, or DevOps roles tied to Java, developer productivity, or CI/CD pipelines.
  • Exposure to Linux distribution and packaging ecosystems or reproducible build systems (e.g., Alpine, Wolfi, Debian, Bazel, Nix).
