Chainguard is a venture-backed software supply-chain security company that delivers hardened, secure, production-ready builds of open source software. The company serves Fortune 500 enterprises and global leaders including OpenAI, Snap Inc., and Snowflake.
The Repository team owns the customer-facing infrastructure that serves libraries and is expanding to support containers, APKs, and other artifact types. You will join as a Senior Software Engineer to lead the architecture and implementation of core systems: package registries, APIs, and production services that securely serve artifacts at high scale and reliability.
This is an infrastructure-heavy backend role at the intersection of software engineering and production infrastructure. You will write Go services, build and operate customer-facing systems, improve reliability and performance, and shape how Chainguard Repository expands into a broader artifact platform.
Key responsibilities:
- Own technical direction for key parts of Chainguard Repository, including customer-facing registries, APIs, and serving systems
- Design, build, and operate high-availability backend services in Go that serve libraries and lay the foundation for containers, images, and APK repositories
- Lead work on scalability, reliability, observability, and load testing for production systems customers depend on directly
- Drive technical decisions around repository architecture, service boundaries, and operational patterns for artifact-serving infrastructure at scale
- Partner closely with engineers across Chainguard to create a cohesive repository experience and unlock support for more artifact types
This is an early, high-impact area for the company with significant growth potential.
REQUIREMENTS:
- 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 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; proactively identify problems, chase them down, and improve the platform before issues become bottlenecks
- Excellent communication and collaboration skills, especially in a remote environment
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
