About the Role
We are developing the next generation of travel and expense (T&E) technology, leveraging AI and large language models. Our mobile platform integrates advanced AI with strong product and UX design to provide travelers with an intelligent companion, moving beyond a simple booking app. The application aims to understand user needs, anticipate requests, and offer personalized assistance through conversational UI and rich, immersive interactions. You will play a key role at the intersection of AI and mobile, helping to shape how travelers engage with this product on iOS.
Responsibilities
- 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, focusing on performance and privacy.
- Utilize metrics, experimentation, and validation (analytics, A/B tests, logging) to iterate on features and enhance quality.
- Translate complex AI/ML capabilities into simple, intuitive mobile interactions.
- Employ AI tools (e.g., Claude Code, LLM-based coding assistants) to accelerate development while maintaining a high-quality, well-tested codebase.
- Collaborate with product, design, and backend teams in a fast-paced environment.
Requirements
- 5+ years of professional development experience with strong Swift skills, building high-quality iOS apps.
- Deep understanding of Swift and the iOS SDK, including Swift concurrency (async/await, Task, actors), structured concurrency, and modern GCD usage.
- Proficiency with SwiftUI for building production UIs; familiarity with UIKit and interoperability is a plus.
- Experience with Combine or other reactive patterns, and understanding when to use them versus async/await.
- Strong grasp of iOS architecture patterns (e.g., MVVM, Clean Architecture, modularization) suitable for AI-powered, stateful, and real-time features.
- Solid understanding of JSON, REST, WebSockets, streaming APIs, and robust networking layers (error handling, retries, offline support).
- Experience with offline storage, background processing, threading, and push notifications.
- Curiosity about new interaction models (chat, agents, multimodal UI, etc.).
- Experience using AI development tools (e.g., Claude Code, GitHub Copilot) in your workflow, with good judgment regarding code quality and security.
- Familiarity with LLM-driven features (prompt design, integrating LLM APIs, handling latency, fallbacks, guardrails) and/or conversational UX.
- Track record of building consumer-facing apps; ideally, you have shipped to the App Store and iterated based on user feedback and metrics.
