About the role

iOS Developer (AI-focused)

Own the iOS client experience, specifically how AI feels, responds, and performs for users. This is a hands-on role building a production-grade iOS app where AI interactions are central to the product experience.

Responsibilities

  • Build and maintain production iOS applications using Swift and SwiftUI.
  • Integrate AI-powered features via backend APIs.
  • Design AI interaction UX patterns, including:
    • Loading states
    • Streaming responses
    • Retries and fallbacks
  • Optimize for performance, memory usage, and battery efficiency.
  • Capture user signals/feedback to support AI evaluation and iteration.
  • Collaborate with backend and ML engineers on API design and system behavior.
  • Ensure high App Store quality, stability, and production reliability.

Requirements

  • 3+ years of iOS development experience with Swift.
  • Hands-on experience integrating AI-powered features into mobile apps.
  • Strong knowledge of async/await, concurrency, and background tasks.
  • Solid iOS performance and memory optimization skills.
  • Experience shipping and maintaining production iOS applications.
  • Comfort designing for latency, partial failure, and non-deterministic AI behavior.
  • Exposure to CoreML or other lightweight on-device ML.
  • Familiarity with feature flags / remote configuration systems.
  • Strong intuition for AI UX patterns and user trust considerations.

Outcomes

  • Stable, smooth, reliable real-world iOS usage.
