What you need

5+ years of professional development experience with strong Swift skills, building high quality iOS apps
Deep understanding of Swift and the iOS SDK, including:

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)

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
