Senior Builder, Amazon

• Experience as a mentor, tech lead or leading an engineering team
• 7+ years of non-internship professional software development experience
• 5+ years of programming with at least one software programming language experience
• 5+ years of leading design or architecture (design patterns, reliability and scaling) of new and existing systems experience
• 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 shipping and operating features 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

Desirable

• Ring is redefining how millions of people interact with their homes every single day
• As a Senior Builder on this feature team, you'll own and evolve some of the most foundational user experiences in the Ring app — the surfaces customers touch every time they open it, and the experiences other engineering teams build on top of
• When you ship here, the impact compounds across the entire app
• This team also owns experiences that sit at the heart of Ring's security promise to customers — the kind of work where reliability, latency, and clarity aren't nice-to-haves, they're the product
• We need senior engineers with deep iOS or Android expertise — ideally both, or equivalent depth in a cross-platform framework like React Native — who can navigate that bar and raise it
• This is also a role for someone who sees AI as a fundamental shift in how software is built, tested, shipped, and maintained
• You'll champion AI-powered development practices on the team and influence how engineers across Ring apply them to feature work
• Lead the technical design and delivery of foundational user experiences that millions of customers use every day, and that other Ring teams build their features on top of
• Own the architecture, quality, and long-term health of the surfaces this team is responsible for — making decisions that balance velocity, reliability, and scale
• Champion AI-powered development practices on the team — code generation, automated testing, intelligent code review, AI-assisted debugging — and help raise the bar for how the broader org applies them
• Set the bar for performance, reliability, and craft on experiences where customers expect responsiveness and trust at all times
• Partner closely with product, UX, backend, and platform teams to deliver cohesive end-to-end experiences across Ring's connected device ecosystem
• Mentor and grow the engineers around you — through design reviews, code reviews, pairing, and technical leadership
• Drive operational excellence: observability, on-call response, defect resolution, and continuous improvement of CI/CD and testing for your surfaces
• Shape the technical direction of experiences that anchor the Ring app and that other teams depend on — your decisions ripple far beyond your own surface area
• Tackle hard problems at the intersection of UX, performance, and reliability for features that customers rely on for their sense of safety
• Operationalize AI-powered workflows in your own development and across the team, identifying where AI can eliminate toil and accelerate delivery
• Engage in deep technical discussions about architecture, state management, navigation models, and platform-specific tradeoffs with experienced mobile engineers
• Build features and infrastructure that protect millions of homes — your work has real, tangible impact on people's sense of safety and connection
• This team owns foundational user experiences that anchor the Ring app and that many other teams build features into. We hold ourselves to a high bar because the experiences we own are the ones customers see most often and rely on most heavily — including the moments when Ring's security promise is on the line
• 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, you won't just receive that vision — you'll help carry it forward into how Ring builds mobile software
