About the Role:

Realtor.com's mobile apps help millions of people each month search for, tour, finance, and move into their next home. The Mobile Platform team owns the shared foundations, tools, and standards that let our product teams ship quickly and confidently on iOS and Android. We are looking for an exceptional Senior Staff Engineer to join our Mobile Platform team and set the technical direction for the foundations behind our consumer iOS and Android applications. The ideal candidate understands modern mobile engineering deeply on both platforms: not only Swift and Kotlin, but also how high-scale consumer apps combine native capabilities, web experiences, shared services, experimentation, and modular design. 

• You will have depth in one platform and strong working proficiency in the other.
• You will own the health, system design, quality, and evolution of the shared mobile platform that our feature teams build on.
• You have led significant mobile modernization efforts and know how to decide what should stay native, what can safely move to web-based experiences, and how the two should interact without compromising performance, reliability, security, accessibility, or customer experience.

Top Reasons to Apply:

1. Drive Mobile Modernization: Play a key role in re-architecting Realtor.com's iOS and Android applications, introducing modern, modular architectures and reducing legacy technical debt.
2. Shape the Future of AI-Powered Engineering: Work with advanced AI development agents and help establish new approaches to software delivery, testing, architecture, and code review. 
3. Influence Two Mobile Platforms: Provide cross-platform architectural leadership for both iOS and Android, collaborating with established technical leads and influencing engineering practices across Realtor.com's mobile organization.

What You'll Do:

• Set the technical direction, roadmap, and engineering standards for the mobile platform across iOS and Android.
• Help adopt cross-platform frameworks such as KMP or React Native where they make sense, respecting native conventions.
• Build and maintain the shared foundations feature teams rely on: modular design, networking, authentication, navigation, analytics, feature flags, and experimentation.
• Improve crash-free users, startup time, responsiveness, app size, observability, and release quality across both apps.
• Modernize legacy code, dependencies, build systems, testing, and release pipelines.
• Establish automated testing across unit, integration, UI, device, and end-to-end scenarios.
• Evolve CI/CD, progressive rollout, rollback, and App Store / Google Play release practices.
• Lead technical design reviews and make pragmatic decisions that balance speed, maintainability, and customer impact.
• Lead production incident response and use telemetry and customer data to improve reliability.
• Partner with feature teams and with Web, Product, Design, Analytics, and Backend teams.
• Mentor engineers and raise the technical bar across the mobile organization.

What You'll Bring:

• 10+ years of related experience.
• Bachelor's degree or equivalent experience.
• Deep expertise in one mobile platform and strong working proficiency in the other:
  iOS: Swift, SwiftUI, UIKit, Xcode, concurrency, networking, persistence, security, and performance optimization.
  Android: Kotlin, Jetpack Compose, Android SDK, Coroutines/Flow, networking, persistence, security, and performance optimization.
• Strong understanding of modern mobile design approaches.
• Meaningful experience building apps that combine native capabilities with WebViews or hybrid experiences.
• Experience modernizing large, mature consumer applications at high scale, preferably with millions of users.
• Strong knowledge of mobile observability, crash analytics, performance monitoring, experimentation, and release health.
• Experience with App Store and Google Play release management, phased rollouts, feature flags, and rapid rollback.
• Strong technical decision-making, prioritization, and mentoring skills.
• Ability to communicate effectively with both deeply technical teams and senior business and product leaders.
