Sr. Builder - Mobile; Platform), Ring

Position: Sr. Builder - Mobile (Platform), Ring
Description

Ring is redefining how millions of people interact with their homes every single day. 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. Your mastery of modern mobile development — Swift, Kotlin, React Native, the latest platform APIs, modern architectural patterns, and the tooling that surrounds them — will be instrumental in charting Ring's path toward faster iteration cycles without sacrificing the quality and performance our customers expect at scale.

The App Platform team sets the overall technical direction for mobile development across Ring and Blink. You'll be a key member of this team, making decisions that ripple across our entire mobile engineering organization.

Key job responsibilities
You will:

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

A day in the life
As a Senior Builder on the App Platform team, you will:

Shape the future of how Ring builds mobile software — your architectural and tooling decisions will define the development experience for teams across the organization

Tackle novel challenges that come with operating a large-scale production application serving millions of daily users

Experiment with and operationalize AI-powered development workflows, identifying where AI can eliminate toil, catch defects earlier, and accelerate delivery

Engage in deep technical discussions about application architecture, rendering performance, state management, and platform-specific tradeoffs with some of the best mobile engineers in the industry

Build platform capabilities and infrastructure that protect millions of homes — your work has real, tangible impact on people's sense of safety and connection

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. If you want to work on problems where your decisions matter at massive scale, and where you have the freedom to chart a genuinely new course, this is the team.

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…
