About the job
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.
Responsibilities
- 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
Qualifications
Minimum
- 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
Preferred
- Bachelor's degree in computer science or equivalent
- Experience building mobile platform SDKs, shared libraries, or developer tooling consumed by other engineering teams
- Demonstrated adoption of AI-powered development tools and practices (AI-assisted coding, automated test generation, intelligent code review, AI-driven debugging)
- Experience integrating cross-platform frameworks (React Native, Flutter, Kotlin Multiplatform) into existing native applications, or operating hybrid native + cross-platform architectures at scale
- Experience with monorepo tooling, modularization strategies, or build system optimization (Bazel, Gradle, SwiftPM, Tuist) for large mobile codebases
- Experience with streaming video, real-time communication protocols (WebRTC, HLS, RTSP), or media playback at scale
- Experience with connected device ecosystems (IoT, Bluetooth, local network protocols, device pairing/provisioning)
- Performance optimization experience for resource-constrained environments (battery, memory, network)
