Job description

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.

Staff Software Engineer (Repositories)

The role

If you’re excited by the idea of building the trusted front door to secure open source software, this role is for you. Chainguard’s Repository team owns the customer-facing infrastructure that serves libraries today and is laying the foundation for a unified repository experience across more artifact types over time, including containers and APKs.

We’re hiring a Staff Software Engineer to help lead the architecture and implementation of the Repository team’s core systems: package registries, APIs, and production services that securely serve artifacts to customers at high scale and high reliability.

This is an infrastructure-heavy backend role. It sits at the intersection of software engineering and production infrastructure: writing Go services, building and operating customer-facing systems, improving reliability and performance, and shaping how Chainguard Repository expands beyond Libraries into a broader artifact platform.

This is an early, high-impact area for the company.

What you'll do

• Own the technical direction for key parts of Chainguard Repository, including customer-facing registries, APIs, and serving systems that make Chainguard artifacts easy to consume securely and reliably.
• Design, build, and operate high-availability backend services in Go that serve libraries today and help lay the foundation for containers, images, and APK repositories over time.
• Lead work on scalability, reliability, observability, and load testing for production systems that customers depend on directly.
• Drive technical decisions around repository architecture, service boundaries, and the operational patterns needed to run artifact-serving infrastructure at scale.
• Partner closely with engineers across Chainguard to create a cohesive repository experience and unlock support for more artifact types over time.
• Mentor other engineers, raise the bar on design and code review, and act as a force multiplier in a fast-moving team where staff engineers are expected to own meaningful deliverables and help shape how the team works.

What we're looking for

• 8+ years of experience building and operating production backend or infrastructure systems, with clear evidence of staff-level ownership and technical leadership.
• Strong Go experience, or deep backend systems experience with the ability to ramp quickly in Go.
• Experience building or operating customer-facing infrastructure such as package registries, artifact repositories, APIs, developer platforms, or other high-scale serving systems.
• Experience deploying and managing services in production, with strong judgment around reliability, observability, performance, and operational tradeoffs.
• Comfort working across application and infrastructure layers, including service development, cloud infrastructure, and infrastructure as code tools such as Terraform.
• Strong systems instincts and curiosity: you proactively identify problems, chase them down, and improve the platform before issues become bottlenecks for customers or internal teams.
• Excellent communication and collaboration skills, especially in a remote environment where staff engineers are expected to drive alignment across teams and help turn ambiguity into momentum.

Nice to have

• Experience with package registries, artifact serving, repository products, or adjacent systems such as Docker registries, GitLab package services, Artifactory, Nexus, or similar platforms.
• Familiarity with software supply chain security concepts such as provenance, SBOMs, and trusted artifact distribution.
• Open source experience, especially in tooling, package ecosystems, or infrastructure used by developers at scale.
• Experience supporting or expanding multi-artifact repository platforms across libraries, containers, OS packages, or similar artifact types.
