Senior Software Engineer, Docker

• 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
• Significant experience building and operating backend systems in production
• Strong programming skills in either Clojure or Go with demonstrated willingness and ability to learn the other
• Experience designing and maintaining distributed systems or microservices
• Strong understanding of cloud-native systems (AWS or GCP), APIs, and data stores
• Proven experience mentoring engineers and guiding projects from design to delivery
• Excellent communication skills in a remote, async-first environment
• A grounded, practical approach to balancing technical depth with business outcomes
• 6+ years of directly applicable experience
• Bachelor’s degree in Computer Science, Engineering, or a related field, or equivalent practical experience
• You're genuinely enthusiastic about working in whichever language you have less experience with. If you're primarily a Go engineer, you're excited to dive into Clojure and functional programming (potentially for an extended period)
• If you're primarily a Clojure engineer, you're eager to build Go expertise and expand your systems programming skills. We're looking for engineers who see learning new languages as an exciting opportunity

Desirable

• 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
• You'll thrive here if you enjoy leading by example and are genuinely curious about different programming paradigms. Success means you've improved system reliability across both Clojure and Go, contributed to architectural decisions, mentored engineers, grown your expertise in new languages, and helped shape a strong technical culture while keeping delivery front and center
• Design, build, and maintain backend systems and APIs in both Clojure and Go
• Lead small feature teams through planning, execution, and delivery
• Mentor engineers and share knowledge across the team, particularly during technology transitions
• Make pragmatic architectural decisions and contribute to long-term technical direction
• Work closely with Product, Design, and other engineering teams to deliver end-to-end value
• Improve observability, performance, and security of backend services
• Raise operational standards and take part in the paid on-call rotation
• Champion clear communication, documentation, and technical excellence
• First 30 Days
• Learn our architecture, services, and workflows in both Clojure and Go
• Pair with engineers across both stacks
• Ship your first changes to production
• Get comfortable with our CI/CD, tooling, and deployment practices
• Understand our technology evolution strategy
• First 90 Days
• Own a small project end-to-end
• Lead a feature delivery or reliability improvement initiative
• Contribute meaningfully in both Clojure and Go codebases
• Contribute to documentation, designs, and mentoring
• Build strong working relationships across Product, Design, and Engineering
• One Year Outlook
• You're a trusted technical leader in DevEx
• You're comfortable and productive in both Clojure and Go
• You've improved backend reliability, performance, and delivery velocity
• You've mentored multiple engineers and shaped team-level architecture
• You're leading significant projects and contributing to our platform evolution strategy
