Senior (iOS) Software Engineer

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.

What You'll Do: 

• Design and ship innovative UX patterns forconversational interfaces and AI-driven experiences on iOS
• Architect and buildSwift-first, production grade features usingasync/await, structured concurrency and modern iOS APIs
• Lead implementation ofcontext-aware experiencesusing behavior, preferences, and app state with an emphasis on performance and privacy
• Usemetrics, experimentation, and validation (analytics, A/B tests, logging) to iterate on features and improve quality over time
• Turncomplex AI/ML capabilities into simple, intuitivemobile 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

What We're Looking For: 

• 5+ years of professional development experience with strongSwift skills, building high quality iOS apps 
• Deep understanding ofSwift and the iOS SDK, including:
• • Swift concurrency (async/await, Task, actors), structured concurrency, and modern GCD usage
  • SwiftUI for building production UIs; familiarity with UIKit and interoperability is a plus
  • Experience withCombine or other reactive patterns, and when to prefer them vs. async/await
• Strong grasp ofiOS architecture (e.g., MVVM, Clean Architecture, modularization) suitable for AI‑powered, stateful, and real‑time features
• Solid understanding ofJSON,REST, WebSockets, streaming APIs and robust networking layers (error handling, retries, offline support)
• Experience withoffline storage, background processing, threading andpush notifications
• Curiosity aboutnewinteractionmodels (chat, agents, multimodal UI, etc.)
• 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
• Familiarity withLLM‑driven features (prompt design, integrating LLM APIs, handling latency, fallbacks, guardrails) and/orconversational UX
• Track record buildingconsumer‑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
