Original job description

Description

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 the App Platform team, you'll write the iOS and Android code that the rest of Ring's mobile engineering organization depends on - the SDKs, frameworks, and tooling that dozens of feature teams build on top of.

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. 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.

Key job responsibilities

You Will

Build and maintain native iOS and/or Android platform components - SDKs, shared libraries, architectural primitives, and developer tooling - used by feature teams across Ring
Write high-quality, well-tested code with performance, reliability, and maintainability in mind
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 Ring's mobile architecture, identifying friction points and proposing improvements
Help maintain and improve CI/CD pipelines, build systems, and automated testing infrastructure for the mobile platform
Partner with feature teams to ensure platform components are easy to adopt, well-documented, and fit their real-world needs
Collaborate with backend, product, and UX partners to deliver cohesive end-to-end experiences

A day in the life

As a Builder on the App Platform team, you will:

Ship iOS and Android code that powers features used by millions of customers
Apply modern AI-assisted workflows to write, test, review, and debug code more effectively
Dig into performance, memory, and battery characteristics of the Ring app and find opportunities to make it better
Work closely with feature teams as a platform partner - helping them adopt new APIs, debug tricky integration issues, and ship with confidence
Participate in technical design discussions and code reviews with experienced mobile engineers, sharpening your craft

About The Team

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.

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.

Basic Qualifications

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

Preferred Qualifications

Working knowledge of both iOS and Android platforms, or experience bridging React Native with native modules
Experience adopting AI-powered development tools (AI-assisted coding, test generation, code review, debugging) in real production work
Experience contributing to shared libraries, SDKs, or platform components used by other teams
Experience with performance profiling and optimization on mobile devices
Exposure to streaming video, real-time communication (WebRTC, HLS, RTSP), or connected device protocols (Bluetooth, local network)
