About the Role:

We’re looking for a Senior Software Engineer, Design Systems - Mobile to help build and evolve the native mobile foundations of Realtor.com’s design system. You’ll create reusable UI components, design tokens, documentation, and tooling that help our iOS and Android teams deliver consistent, accessible, and performant experiences.

This is a hands-on engineering role for someone who treats a shared UI library as a product. Your users are the engineers and designers building Realtor.com’s mobile experiences. You’ll work closely with design-system designers and mobile product teams to turn design intent into reliable, well-crafted components that are easy to adopt and maintain.

We’re looking for deep production expertise in either iOS with Swift and SwiftUI or Android with Kotlin and Jetpack Compose, along with the ability to collaborate across both platforms. You’ll lead implementation work in your strongest platform and partner with counterpart engineers on shared foundations, component behavior, and adoption. Experience with iOS is highly preferred. We do not expect expert-level proficiency in both stacks.

Top Reasons to Apply:

A strong mobile design system helps teams spend less time rebuilding UI and more time solving problems for consumers and customers. Your work will make consistent, accessible experiences easier to deliver across iOS and Android, while preserving the native behavior people expect on each platform.

1. Greenfield Development: Opportunity to build new iOS components as Realtor.com modernizes its applications.
2. Company-Wide Impact: Components developed by this engineer will be used across multiple product engineering teams.
3. Specialized Engineering Ownership: Become the primary iOS design systems engineer on a small, experienced team with significant ownership and visibility.

What You'll Do:

• Build and maintain native UI components on your primary platform, with clear APIs, sensible defaults, composable behavior, and well-defined states.
• Partner with designers to translate Figma specifications into production-ready components, resolving interaction details, motion, adaptive layouts, and edge cases together.
• Evolve design-token and theming foundations for color, typography, spacing, shape, and other shared styles, including support for light and dark appearances.
• Collaborate with iOS, Android, and web counterparts on shared design intent while respecting platform-specific conventions, navigation, gestures, and accessibility behavior. Prioritize a coherent experience rather than identical implementations.
• Build accessibility into components from the start, including screen-reader semantics, scalable text, focus behavior, sufficient touch targets, and support for reduced motion.
• Strengthen quality through unit, UI, screenshot or snapshot, accessibility, and consumer-integration testing. Validate behavior across supported OS versions, screen sizes, and device configurations.
• Profile and improve component performance, including rendering, scrolling, memory use, and unnecessary UI updates, while keeping library dependencies and application-size impact manageable.
• Own changes from technical design through implementation, documentation, release, and adoption. Maintain stable APIs, versioning, deprecation plans, and migration guidance for consuming teams.
• Create interactive component catalogs, previews, examples, and usage documentation that help engineers and designers evaluate components and use them correctly.
• Help teams incrementally adopt shared components in existing applications, including interoperability with UIKit or Android Views where needed on your primary platform.
• Review contributions, support consuming teams, and mentor engineers. Use feedback to prioritize improvements and distinguish reusable foundations from product-specific UI.

What You'll Bring:

• 5+ years of professional software-development experience, with substantial hands-on experience building and shipping native mobile applications.  Bachelor's degree or equivalent experience.
• Deep expertise in at least one native UI stack:
  iOS: Swift and production SwiftUI experience, including state and data flow, composition, layout, and interoperability with UIKit.
  Android: Kotlin and production Jetpack Compose experience, including state management, composition, recomposition, layout, and interoperability with Android Views.
• Direct experience building or maintaining a design system or shared UI library used by multiple product teams, not only consuming a UI framework.
• Strong judgment in component API design, reusable abstractions, theming, and separation of presentation from application-specific business logic.
• Practical accessibility experience on your primary platform, including VoiceOver and Dynamic Type on iOS, or TalkBack, semantics, and font scaling on Android.
• Experience testing mobile UI components and diagnosing rendering or interaction problems using native tooling.
• Experience distributing and versioning shared libraries through your platform’s tooling, such as Swift Package Manager or Gradle/Maven, with automated build and release workflows.
• The ability to partner closely with designers, identify gaps in specifications, and explain implementation trade-offs constructively.
• The ability to independently scope and deliver work, communicate risks and dependencies, and support engineers who depend on your code.
• Curiosity about the other mobile platform and a willingness to learn its conventions, review shared specifications, and collaborate on cross-platform decisions.
