Senior Software Engineer, Backend Systems

At Docker, we make app development easier so developers can focus on what matters. Our remote-first team spans the globe, united by a passion for innovation and great developer experiences. With over 20 million monthly users and 20 billion image pulls, Docker is the #1 tool for building, sharing, and running apps—trusted by startups and Fortune 100s alike. We’re growing fast and just getting started. Come join us for a whale of a ride! The Developer Experience (DevEx) team builds the systems and experiences that help millions of developers build, secure, and ship software with confidence. We power critical parts of Docker Scout and Hardened Images, enabling developers and enterprises to understand and improve their software supply chains. We're expanding our backend engineering group to strengthen the systems behind Docker's proprietary content and security capabilities. DevEx operates a polyglot backend infrastructure with significant systems in both Clojure and Go. We're actively evolving our technology strategy: while we maintain sophisticated Clojure-based architecture serving 20M+ users, we're working to consolidate around Go where it makes strategic sense and building new ownership capabilities in Go. What this means for you: In the immediate term, you'll likely work more in Clojure than Go, and this may continue for a sustained period. Over time, the balance will shift. We need engineers who are genuinely excited about working across both languages - learning deeply where you have gaps and contributing to thoughtful evolution of our platform. As a Senior Software Engineer, you'll guide technical design, lead feature delivery, mentor engineers, and help shape our engineering culture through this transition. You'll work with event-driven patterns, distributed systems, and cloud-native infrastructure while helping us evolve our stack pragmatically. This role suits someone who enjoys solving deep technical problems, values working across multiple technologies, and wants to grow their expertise while supporting others through change.
