Full Job Description

COMPANY A1 is building a proactive AI smart assistant for everyday users to bring intelligence to conversations, errands, organising and workflows. Our product focuses on achieving high reliability for long-running workflows, persistent context, and real-world task completion. The system must handle multi-step reasoning, interact with external tools, and remain reliable despite non-deterministic model behavior. ROLE As an iOS Software Engineer, you own the iOS client experience, how AI feels, responds, and performs in users’ hands. This is not a thin integration role. You will build a production-grade iOS application where AI interactions are central to product experience, and performance, reliability, and user trust are critical.   FOCUS - Build and maintain iOS applications using Swift and SwiftUI. - Integrate AI-powered features through backend APIs. - Design UX patterns for AI interactions, including loading states, streaming responses, retries, and fallbacks. - Optimize performance, memory usage, and battery efficiency. - Capture user signals and feedback to support AI evaluation and iteration. - Collaborate closely with backend and ML engineers on API design and system behavior. - Maintain high App Store quality, stability, and production reliability.   IDEAL EXPERIENCES - 3+ years of iOS development experience using Swift. - Hands-on experience integrating AI-powered features into mobile apps. - Strong understanding of async/await, concurrency, and background tasks. - Solid iOS performance and memory optimization skills. - Experience shipping and maintaining production iOS apps. - Comfort designing for latency, partial failure, and non-deterministic AI behavior. - Exposure to CoreML or light on-device ML. - Familiarity with feature flags or remote configuration systems. - Strong intuition for AI UX patterns and user trust considerations.   OUTCOMES - Stable, smooth, and reliable real-world use iOS applications. - Performance is optimized: responsive, low-late
