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 Repositories team owns customer-facing infrastructure that serves Libraries and is building a unified repository experience across multiple artifact types including containers and APKs. This is an infrastructure-heavy backend role at the intersection of software engineering and production infrastructure. You will 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 where 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. Key responsibilities: - 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 and establish the foundation for containers, images, APKs, and other artifact types - 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 Requirements: - 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, incorporate feedback, and work effectively in a remote environment Nice to have: - 5+ years of experience building and operating production backend or infrastructure systems - Strong Go experience, or deep backend systems experience with the ability to become productive in Go quickly - Experience owning backend or infrastructure projects from design through production operation - Experience building or operating customer-facing infrastructure such as package registries, artifact repositories, APIs, developer platforms, or other high-scale serving systems - Strong judgment around reliability, observability, performance, security, and operational tradeoffs - Experience deploying and managing services in production, including familiarity with cloud infrastructure and infrastructure-as-code tools such as Terraform - Strong systems instincts and curiosity: you proactively identify problems, investigate root causes, and improve the platform before issues become bottlenecks - Excellent communication and collaboration skills, particularly in a remote environment where engineers are expected to work across teams and turn ambiguity into progress
