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.

Responsibilities

• Design and ship innovative UX patterns for conversational interfaces and AI-driven experiences on iOS
• 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
• 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.,
• across product, design, and backend in a fast-moving environment

Requirements

• LLM‑based coding assistants) to accelerate development while maintaining a high‑quality, well‑tested codebase
• 5+ years
• of professional development experience with strong Swift skills, building high quality iOS apps
• Deep understanding of
• Swift
• 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
• Combine
• or other reactive patterns, and when to prefer them vs. async/await
• Strong grasp of
• iOS architecture
• (e.g., MVVM, Clean Architecture, modularization) suitable for AI‑powered, stateful, and real‑time features

Solid understanding of

• REST, WebSockets, streaming APIs and robust networking layers (error handling, retries, offline support)
• offline storage, background processing, threading and push notifications
• Curiosity about
• new
• interaction
• models
• (chat, agents, multimodal UI, etc.)
• Experience using
• (e.g., Claude Code, GitHub Copilot, etc.) as part of your workflow, with good judgment about code quality and security

Track record building

• consumer‑facing apps;
• ideally you’ve shipped to the App Store and iterated from user feedback and metrics

Preferred

• LLM‑driven features
• (prompt design, integrating LLM APIs, handling latency, fallbacks, guardrails) and/or conversational UX
