The role If you’re excited by the idea of helping build the trusted front door to secure open source software, this role is for you. Chainguard’s Repositories team owns the customer-facing infrastructure that serves Libraries today and is laying the foundation for a unified repository experience across more artifact types, including containers and APKs. We’re hiring a Software Engineer to help build and operate the Repository team’s core systems: package registries, APIs, and production services that securely serve artifacts to customers at scale and with high reliability. This is an infrastructure-heavy backend role at the intersection of software engineering and production infrastructure. You’ll develop Go services, contribute to customer-facing systems, improve reliability and performance, and learn how production infrastructure supports a broader artifact platform. This is an early, high-impact area for the company. You’ll work closely with experienced engineers, take ownership of well-defined projects, and grow your ability to make effective technical decisions in a fast-moving environment. What you'll do Build and improve customer-facing registries, APIs, and artifact-serving systems that make Chainguard software easy to consume securely and reliably. Implement well-scoped projects and features from technical design through testing, rollout, monitoring, and iteration, with support from more experienced engineers. Develop and operate backend services in Go that serve Libraries today and help establish the foundation for containers, images, APKs, and other artifact types over time. Contribute to work involving scalability, reliability, observability, performance, and load testing for production systems. Participate in design discussions and help make thoughtful decisions about service boundaries, APIs, data flows, and operational patterns. Work with engineers and product partners across Chainguard to solve problems and deliver a cohesive repository experience. Review code, ask questions, share what you learn, and contribute to a supportive engineering team. Help investigate and resolve production issues, building your operational judgment and understanding of how customer-facing systems run in practice. What we're looking for 2+ years of experience building software, with some experience working on backend or infrastructure systems. Experience with Go, or strong programming experience in another language and the ability to learn Go quickly. Experience contributing to software projects from implementation through testing and release. Interest in building customer-facing infrastructure such as package registries, artifact repositories, APIs, developer platforms, or other backend systems. Familiarity with software engineering fundamentals, including testing, code review, debugging, and version control. Exposure to deploying or operating services in production, or a strong interest in developing those skills. Familiarity with cloud infrastructure or infrastructure-as-code tools such as Terraform is helpful but not required. A systems-oriented mindset and curiosity: you like understanding how things work, investigating problems, and improving your solutions over time. Clear communication and a collaborative approach, including the ability to ask for help, incorpor
