Senior Software Engineer (Repository)

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 Senior 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.

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.

5+ years of experience building and operating production backend or infrastructure systems, with clear evidence of senior level ownership.

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
