Expect to get together quarterly for intense in-person working sessions called “surges.” learn more about working at Coinbase. Coinbase's Developer Infrastructure group builds the tools and platforms that every Coinbase engineer relies on to build, test, ship, and operate software. Our teams collectively own the path from commit to production — scalable CI and build infrastructure, the platform that moves code safely to production, and the test infrastructure that gives engineers fast, trustworthy signals. We're hiring Software Engineers across several teams in the group, and you'll be matched to the one that best fits your strengths and interests. Wherever you land, you'll help build and operate foundational platform services used by all of Coinbase engineering, where a single improvement compounds across thousands of engineers. This is high-leverage systems work at a financial-grade reliability and security bar. What you'll do: - Build, ship, and help operate features and components of core developer-infrastructure services — spanning CI and build systems, deployment orchestration, and test infrastructure — that are fast, reliable, and secure by default at Coinbase scale. - Contribute to improvements in the metrics every engineer feels: build and CI wall time, deploy speed and safety, and test feedback time and flakiness. - Own well-scoped components end to end — from implementation through testing, rollout, and monitoring — and participate in your team's on-call rotation. - Write high-quality, well-tested, observable code, and build for production from day one. - Collaborate with engineering teams across Coinbase (your customers) to understand pain points and translate them into concrete platform improvements. - Contribute to technical design discussions for team projects, and independently drive your own work items to completion. - Grow your impact by sharing knowledge, giving thoughtful code reviews, and raising the quality bar around you. Required Skills and Experience: - 2+ years building and operating production software, with solid fundamentals in distributed systems and proficiency (or a strong ability to ramp) in a language like Go (or similar). - A track record of shipping backend or platform features that other engineers or services depend on, with ownership from implementation through production. - Good operational instincts — you care about reliability, security, and observability, and you write code with production in mind. - Clear communication and the ability to drive scoped projects to completion with limited guidance and collaborate effectively across a team. - A customer-focused mindset: you measure success by the impact your systems have on other engineers. - Exposure to a developer infrastructure or platform domain: CI/CD, build systems, deployment/release tooling, test infrastructure, or developer productivity engineering. - Experience with Kubernetes, AWS, GitHub Actions, Terraform, or containers (Docker/OCI). - Experience with observability and performance tooling (e.g., Datadog) to measure and improve system behavior. - Utilizes generative AI responsibly, maintaining human oversight to deliver business-ready outputs and drive measurable improvements in workflow efficiency, cost, and quality.
