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.Success in This Role Looks LikeYou'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.ResponsibilitiesDesign, build, and maintain backend systems and APIs in both Clojure and GoLead small feature teams through planning, execution, and deliveryMentor engineers and share knowledge across the team, particularly during technology transitionsMake pragmatic architectural decisions and contribute to long-term technical directionWork closely with Product, Design, and other engineering teams to deliver end-to-end valueImprove observability, performance, and security of backend servicesRaise operational standards and take part in the paid on-call rotationChampion clear communication, documentation, and technical excellenceQualificationsRequired:Significant experience building and operating backend systems in productionStrong programming skills in either Clojure or Go with demonstrated willingness and ability to learn the otherExperience designing and maintaining distributed systems or microservicesStrong understanding of cloud-native systems (AWS or GCP), APIs, and data storesProven experience mentoring engineers and guiding projects from design to deliveryExcellent communication skills in a remote, async-first environmentA grounded, practical approach to balancing technical depth with business outcomes6+ years of directly applicable experienceBachelor’s degree in Computer Science, Engineering, or a related field, or equivalent practical experience.Strong Plus:Production experience with both Clojure and GoExperience with Datomic, event-driven architectures, or KafkaExperience working through technology migrations or in polyglot environmentsFunctional programming background (if coming from Go) or systems programming background (if coming from Clojure)Critical mindset: 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.What to ExpectFirst 30 DaysLearn our architecture, services, and workflows in both Clojure and GoPair with engineers across both stacksShip your first changes to productionGet comfortable with our CI/CD, tooling, and deployment practicesUnderstand our technology evolution strategyFirst 90 DaysOwn a small project end-to-endLead a feature delivery or reliability improvement initiativeContribute meaningfully in both Clojure and Go codebasesContribute to documentation, designs, and mentoringBuild strong working relationships across Product, Design, and EngineeringOne Year OutlookYou're a trusted technical leader in DevExYou're comfortable and productive in both Clojure and GoYou've improved backend reliability, performance, and delivery velocityYou've mentored multiple engineers and shaped team-level architectureYou're leading significant projects and contributing to our platform evolution strategyDocker considers sponsorship on a case-by-case basis based on business needs.We use Covey as part of our hiring and / or promotional process for jobs in NYC and certain features may qualify it as an AEDT.
