Senior Builder, Amazon

• Experience as a mentor, tech lead or leading an engineering team
• 7+ years of programming with at least one software programming language experience
• 7+ years of leading design or architecture (design patterns, reliability and scaling) of new and existing systems experience
• 7+ years of non-internship professional software development experience
• 7+ years of professional software development experience building mobile applications
• 5+ years of deep native iOS (Swift/Objective-C) or Android (Kotlin/Java) development, with working knowledge of the other platform — or equivalent depth building production mobile apps with React Native or a comparable cross-platform framework, with strong familiarity with at least one underlying native platform
• Demonstrated experience building and operating applications at large scale (millions of daily active users)
• Experience designing and implementing modern mobile architectures (e.g., MVVM, MVI, Clean Architecture, unidirectional data flow) using current platform tooling (SwiftUI/UIKit, Jetpack Compose, Coroutines, Combine, etc.)
• Strong command of the full mobile SDLC including CI/CD, automated testing, release management, and production monitoring
• Experience leading technical initiatives that span multiple teams or influence organizational engineering practices

Desirable

• As a Senior Builder on the App Platform team, you won't just write code — you'll set the technical direction for one of the most widely-used connected device applications in the world
• Native mobile is the foundation our customers rely on, and we need engineers with deep iOS or Android expertise — ideally both, or equivalent depth in a cross-platform framework like React Native — to architect what comes next
• This is a role for someone who sees AI not as a buzzword but as a fundamental shift in how software is built, tested, shipped, and maintained
• You'll champion an AI-powered software development lifecycle across the mobile organization, influencing how hundreds of engineers build applications
• Your mastery of modern mobile development — Swift, Kotlin, React Native, the latest platform APIs, modern architectural patterns, and the tooling that surrounds them — will be instrumental in charting Ring's path toward faster iteration cycles without sacrificing the quality and performance our customers expect at scale
• The App Platform team sets the overall technical direction for mobile development across Ring and Blink
• You'll be a key member of this team, making decisions that ripple across our entire mobile engineering organization
• Define and drive the technical strategy for Ring's mobile architecture, balancing development velocity with the performance and reliability customers expect from a home security product
• Champion AI-powered development practices across the mobile organization — from AI-assisted code generation and automated testing to intelligent code review and predictive quality assurance
• Architect mobile solutions that serve tens of millions of daily active users on iOS and Android
• Establish frameworks, SDKs, tooling, and best practices that accelerate feature development, improve code quality, increase testability, strengthen observability, and streamline the path from idea to production
• Drive continuous improvement in CI/CD pipelines, automated testing strategies, modularization, and release engineering for large-scale codebases
• Mentor and influence engineers across the organization, raising the bar for mobile development practices and fostering a culture of technical excellence and experimentation
• Partner with product, UX, backend, and infrastructure teams to deliver cohesive features that span the full stack of Ring's connected device ecosystem
• Shape the future of how Ring builds mobile software — your architectural and tooling decisions will define the development experience for teams across the organization
• Tackle novel challenges that come with operating a large-scale production application serving millions of daily users
• Experiment with and operationalize AI-powered development workflows, identifying where AI can eliminate toil, catch defects earlier, and accelerate delivery
• Engage in deep technical discussions about application architecture, rendering performance, state management, and platform-specific tradeoffs with some of the best mobile engineers in the industry
• Build platform capabilities and infrastructure that protect millions of homes — your work has real, tangible impact on people's sense of safety and connection
• Ring's App Platform team is the technical backbone of our mobile development organization
• We own the cross-cutting concerns — architecture, tooling, frameworks, performance, and developer experience — that enable dozens of feature teams to ship high-quality software to tens of millions of users
• We combine the ambition and speed of a startup with the scale, resources, and impact of Amazon
• If you want to work on problems where your decisions matter at massive scale, and where you have the freedom to chart a genuinely new course, this is the team
• You'll work closely with senior leadership every day
• Ring is intentionally structured to break down the corporate org-chart barriers that slow teams down — builders sit shoulder-to-shoulder with the leaders setting direction, and decisions happen in the room rather than three layers up
• That leadership is deeply hands-on, actively reshaping how we think about AI in software development, and shaped by a vision that has redefined what neighborhood safety looks like for communities around the world
• As a Senior Builder on App Platform, you won't just receive that vision — you'll help carry it forward into how Ring builds mobile software
