Our mobile platform blends cutting-edge AI with strong product and UX so travelers get an intelligent companion, not just another booking app. The app should understand needs, anticipate requests, and deliver personalized help through conversational UI and rich, immersive interactions. You'll work at the intersection of AI and mobile, helping define how travelers interact with this kind of product on iOS. What You'll Do: * Design and ship innovative UX patterns for conversational interfaces and AI-driven experiences on iOS * Architect and build Swift-first, production grade features using async/await, structured concurrency and modern iOS APIs * Lead implementation of context-aware experiences using behavior, preferences, and app state with an emphasis on performance and privacy * Use metrics, experimentation, and validation (analytics, A/B tests, logging) to iterate on features and improve quality over time * Turn complex AI/ML capabilities into simple, intuitive mobile interactions * Use AI tools (e.g., Claude Code / LLM-based coding assistants) to accelerate development while maintaining a high-quality, well-tested codebase * Collaborate across product, design, and backend in a fast-moving environment ## Related Videos - [SwiftUI In Production](https://www.wearedevelopers.com/videos/134-swiftui-in-production) - [From Zero to Mobile Developer in 45 Minutes With SwiftUI](https://www.wearedevelopers.com/videos/183-from-zero-to-mobile-developer-in-45-minutes-with-swiftui) - [Xcode development redefAIned](https://www.wearedevelopers.com/videos/100195-xcode-development-redefained) - [Tips and Tricks for Working with JSON](https://www.wearedevelopers.com/videos/1229-tips-and-tricks-for-working-with-json) - [Harnessing Apple Intelligence: Live Coding with Swift for iOS](https://www.wearedevelopers.com/videos/1515-harnessing-apple-intelligence-live-coding-with-swift-for-ios) - [Unsolved mysteries between Usability and Accessibility in iOS](https://www.wearedevelopers.com/videos/737-unsolved-mysteries-between-usability-and-accessibility-in-ios) ## Related Articles - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Dev Digest 118 - not a total recall](https://www.wearedevelopers.com/magazine/452-dev-digest-118-not-a-total-recall) - [A Guide to Choosing the Right Tools for App Developers](https://www.wearedevelopers.com/magazine/391-a-guide-to-choosing-the-right-tools-for-app-developers) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [Dev Digest 132 - Binging WADFlix?](https://www.wearedevelopers.com/magazine/473-dev-digest-132-binging-wadflix) - [Dev Digest 137 - AI'm not sure about this](https://www.wearedevelopers.com/magazine/485-dev-digest-137-ai-m-not-sure-about-this)
