iOS Software Engineer (AI Mobile Apps)

About the role

ActAI builds proactive mobile applications that bring AI into everyday communication, coordination and collaboration with minimal prompting. As an iOS Software Engineer you own the iOS client experience: how AI feels, responds and performs in users' hands. 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 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
• Ability to work in a small, hands-on team, make collective decisions and execute independently

Required skills

• Strong understanding of async/await, concurrency and background tasks
• Solid iOS performance and memory optimization skills
• 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

The interview process involves up to four virtual or onsite interviews, followed by a prompt decision. The tech stack includes Swift, SwiftUI, SQL / noSQL, TensorFlow Lite and CoreML.
