Builder, Amazon

• This is a role for someone who loves mobile development and wants to go deep — whether that's modern Swift and Kotlin or React Native paired with strong native fundamentals — using the latest platform APIs, clean architecture, and the kind of craftsmanship that holds up at the scale of tens of millions of users
• 3+ years of full software development life cycle, including coding standards, code reviews, source control management, build processes, testing, and operations experience
• 3+ years of professional software development experience building mobile applications
• 3+ years of native iOS (Swift/Objective-C) or Android (Kotlin/Java) development using modern tooling and architectural patterns — or 3+ years of production React Native (or comparable cross-platform) experience with working knowledge of the underlying native platforms
• Hands-on experience with modern UI frameworks (SwiftUI/UIKit, Jetpack Compose, or React Native) and modern concurrency patterns (Swift Concurrency, Combine, Coroutines, async JS)
• Solid understanding of mobile fundamentals: app lifecycle, memory and performance, networking, persistence, and testing
• Experience writing and maintaining unit and UI tests, and working within a CI/CD pipeline

Desirable

• Ring builds the apps that millions of people open every day to check on their homes, see who's at the door, and stay connected to what matters
• As a Builder on this team, you'll work on foundational user experiences that anchor the Ring app — the surfaces customers touch every time they open it, and the experiences other engineering teams build on top of
• Some of what this team owns is also central to Ring's security promise to customers, where reliability and clarity are part of the product itself
• You'll also work alongside engineers who are aggressively adopting AI across the development lifecycle, and you'll be expected to use those tools well — not as a novelty, but as a real lever to ship better software faster
• Design, build, and ship features for Ring mobile applications that millions of customers use every day
• Write high-quality, well-tested code with performance, reliability, and maintainability in mind — especially for experiences where customer trust depends on it
• Use AI-powered development tools effectively across your day-to-day work: code generation, test authoring, code review, debugging, documentation, and defect resolution
• Contribute to the evolution of the team's architecture, identifying friction points and proposing improvements
• Collaborate with product, UX, backend, and platform partners to deliver cohesive end-to-end experiences
• Help maintain operational excellence — resolving issues, fixing bugs, improving observability, and keeping CI/CD healthy
• Participate in design and code reviews, raising the bar for the team's craft
• Ship iOS and/or Android code that powers experiences used by millions of customers
• Apply modern AI-assisted workflows to write, test, review, and debug code more effectively
• Work on features where reliability, responsiveness, and clarity are part of the product itself
• Partner with backend engineers to integrate with services and real-time data flows
• Participate in technical design discussions and code reviews with experienced mobile engineers, sharpening your craft
• 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
• You'll work closely with senior leadership in an organization intentionally designed to break down the corporate org-chart barriers that slow most companies down
• Builders sit shoulder-to-shoulder with the leaders setting direction — that leadership is 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. You'll feel that influence directly in the pace, the ambition, and the access you have to the people steering the work
• We combine the ambition and speed of a startup with the scale, resources, and impact of Amazon
