About The Position

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.

Requirements

• 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

Nice To Haves

• Bachelor's degree in computer science or equivalent
• Demonstrated adoption of AI-powered development tools and practices (AI-assisted coding, automated test generation, intelligent code review, AI-driven debugging)
• Experience building features or surfaces that other teams integrate into or extend
• Experience working on user experiences with strict reliability, latency, or correctness requirements
• Experience with modern navigation, state management, and complex UI composition at scale
• Experience integrating cross-platform frameworks (React Native, Flutter, Kotlin Multiplatform) into existing native applications
• Performance optimization experience for resource-constrained environments (battery, memory, network)
• Experience with REST APIs, real-time/event-driven services, or push-based architectures

Responsibilities

• 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

Benefits

• health insurance (medical, dental, vision, prescription, Basic Life & AD&D insurance and option for Supplemental life plans, EAP, Mental Health Support, Medical Advice Line, Flexible Spending Accounts, Adoption and Surrogacy Reimbursement coverage)
• 401(k) matching
• paid time off
• parental leave
