iOS Software Engineer

About the role

ActAI builds proactive, AI-native mobile applications for people who are not used to complex prompting, starting with an agent-first mobile communication app. 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, and performance, reliability and user trust are critical.

Key responsibilities

• 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.

Required profile

• 3+ years of iOS development experience using Swift.
• Hands-on experience integrating AI-powered features into mobile apps.
• Experience shipping and maintaining production iOS apps.
• Comfort designing for latency, partial failure and non-deterministic AI behavior.
• Strong intuition for AI UX patterns and user trust considerations.

Required skills

• Swift and SwiftUI
• Async/await, concurrency and background tasks
• iOS performance and memory optimization
• Exposure to CoreML or light on-device ML
• Familiarity with feature flags or remote configuration systems
• Knowledge of SQL / noSQL and TensorFlow Lite (on-device inference)

The interview process involves 3 to 4 virtual or onsite interviews, evaluated by the technical team, with a prompt decision once a fit is found.
