Principal Software Engineer, Developer Tools (US West Coast)

Principal Software EngineerDocker seeks a Principal Software Engineer to define the technical vision and architecture for our internal Developer Tools team. This is a rare opportunity to establish how software is designed, built, shipped, and operated at Docker. With the addition of AI we are modernizing our SDLC and building the mechanisms that make the right way the easy way for every engineer.You'll own the technical strategy across four interconnected pillars:Platform Engineering & Self-Service: Design and build the internal developer platform that empowers teams across Docker to unblock themselves, rapidly scaffolding, prototyping, deploying, and operating their own services and tools.CI/CD & Build Systems: Define Docker's technical approach to continuous integration, delivery, and build infrastructure. Establish architectural standards for pipeline tooling, GitOps deployment patterns, build substrate, and release engineering.As Principal Software Engineer, you'll partner with engineering leadership across Docker, principal engineers, Security, Infrastructure, and the service teams to author the SDLC tenets that underpin all of this work, and build the mechanisms those tenets run through.Reporting to the Sr Manager of Developer Tools, you'll collaborate closely with engineering leadership across Docker, product engineering teams, platform teams, and ultimately customers as internal tools evolve into product offerings.What Would Make Someone Successful in This RoleYou're a technical leader who excels at the intersection of developer experience, platform engineering, and systems design. You think in platforms and golden paths, building once and enabling dozens of teams to move faster. You have strong opinions on what makes developer tools great: invisible by default, indispensable once adopted, and measurable in the workflows engineers already use.You have deep experience across the breadth of the developer tooling stack, CI/CD, build systems, observability infrastructure, and developer platforms, and working knowledge of LLM integration and AI agent development. You understand the nuances of internal platforms: designing for adoption, not mandate; plugging into existing workflows before standing up new ones; and earning trust through data before expanding scope.You have exceptional judgment on when to build custom solutions versus integrate existing tools, and you're comfortable navigating a rapidly evolving landscape across both AI and developer infrastructure. You balance technical excellence with pragmatism, shipping iteratively while maintaining high quality bars. Most importantly, you lead through influence and mentorship, elevating the entire engineering organization's technical capabilities.ResponsibilitiesTechnical Leadership & Architecture:Define the long-term technical vision and architecture for Docker's developer tooling platform spanning platform engineering, CI/CD, and AI-powered toolsLead authoring of SDLC tenets in partnership with other principal engineers, Security, and Infrastructure and build the mechanisms those tenets bind to (design gates, code review gates, pipeline standards, visibility)Establish architectural patterns, technical standards, and best practices across the developer tooling stackDesign highly available, scalable infrastructure for hosting developer tools, agents, and platform servicesDrive technical decisions on tooling choices, provider strategies, build/deploy substrate, and agent orchestration frameworksPartner with Senior Manager and product leadership to align technical architecture with business objectives and productization opportunitiesSystems Design & Implementation:Architect and build Docker's internal developer platform, the self-service substrate enabling teams to scaffold, deploy, and operate services with minimal frictionDesign and implement CI/CD and build infrastructure that supports Docker's SDLC tenets and GitOps deployment patternsEstablish reliability, security, and performance standards across developer tooling including SLOs, monitoring, incident response, and cost managementDesign integration points between developer tools and existing infrastructure (CI/CD pipelines, observability platforms, deployment systems)Strategic Impact & Innovation:Evaluate emerging technologies across developer tooling, platform engineering, AI/LLM, and agent frameworks to inform Docker's technical strategyDefine and enforce the golden path, the concrete, left-to-right walkthrough of how Docker builds software, and identify where tooling closes gaps vs. where human process doesDrive technical standards for measuring developer tool effectiveness: adoption metrics, productivity gains, pipeline performance, and developer satisfactionLead cross-functional technical discussions influencing company-wide developer tooling architectureDefine technical approach for productizing successful internal developer tools into customer-facing offeringsLeadership & Mentorship:Mentor senior and staff engineers on platform engineering, CI/CD patterns, design, and AI/LLM integrationLead design reviews and technical decision-making across all developer tooling workFoster culture of technical excellence, experimentation, and rapid prototyping within the Developer Tools teamServe as primary technical contact and thought leader for developer tooling across Docker's engineering organizationCollaborate with platform teams (Infrastructure, Security, Agentic Platform, Supply Chain Security) to establish shared technical standards and integration patternsThis role may require participation in an on-call rotation to provide support outside of standard business hours, including evenings, weekends, and holidays, as needed.QualificationsRequired:10+ years software engineering experience with 3+ years in Staff or Principal Engineer rolesBachelor's degree in Computer Science, Engineering, or a related field, or
