Senior Software Engineer (iOS)

• We’re building the next generation of travel and expense (T&E) technology using AI and large language models
• 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
• 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

• Learning & Development- Deep understanding of Swift and the iOS SDK, including:
• Experience with Combine or other reactive patterns, and when to prefer them vs. async/await
• Familiarity with LLM‑driven features (prompt design, integrating LLM APIs, handling latency, fallbacks, guardrails) and/or conversational UX
• SwiftUI for building production UIs; familiarity with UIKit and interoperability is a plus
• Solid understanding of JSON, REST, WebSockets, streaming APIs and robust networking layers (error handling, retries, offline support)
• Strong grasp of iOS architecture (e.g., MVVM, Clean Architecture, modularization) suitable for AI‑powered, stateful, and real‑time features
• Experience with offline storage, background processing, threading and push notifications
• Swift concurrency (async/await, Task, actors), structured concurrency, and modern GCD usage
• 5+ years of professional development experience with strong Swift skills, building high quality iOS apps
• Experience using AI development tools (e.g., Claude Code, GitHub Copilot, etc.) as part of your workflow, with good judgment about code quality and security
• Curiosity about new interaction models (chat, agents, multimodal UI, etc.)
• Track record building consumer‑facing apps; ideally you’ve shipped to the App Store and iterated from user feedback and metrics
• BS in Computer Science or related technical field
