Travel & expense made easy.
The Role
Build and ship Swift-first iOS features that surface AI/LLM-driven conversational and context-aware experiences. Architect performant, privacy-conscious apps using modern concurrency, SwiftUI, networking (REST/WebSockets/streaming), offline storage, background tasks, and analytics-driven iteration. Collaborate with product, design, and backend teams and use AI-assisted development tools while maintaining high code quality and testing standards.
Summary Generated by Built In

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 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

What We're Looking For: 

  • 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
    • SwiftUI for building production UIs; familiarity with UIKit and interoperability is a plus
    • Experience with 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 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, etc.) as part of your workflow, with good judgment about code quality and security
  • Familiarity with LLM‑driven features (prompt design, integrating LLM APIs, handling latency, fallbacks, guardrails) and/or conversational UX
  • 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
The posted pay range represents the anticipated low and high end of the compensation for this position and is subject to change based on business need. To determine a successful candidate’s starting pay, we carefully consider a variety of factors, including primary work location, an evaluation of the candidate’s skills and experience, market demands, and internal parity.
For roles with on-target-earnings (OTE), the pay range includes both base salary and target incentive compensation. Target incentive compensation for some roles may include a ramping draw period. Compensation is higher for those who exceed targets. Candidates may receive more information from the recruiter.
