iOS Software Engineer

ABOUT THE ROLE

A1 is building a proactive AI chat app for everyday users to bring intelligence to conversations, errands, organising and workflows. Unlike traditional chat-based applications, 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.

As an iOS Developer, AI Apps, 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.
