About ActAI
There are over 5 billion users using basic applications today such email, notes, tasks, calendar and they're not AI-native. Our mission is to build proactive applications for anyone in the world, who are not used to complex prompting. We aim to bring intelligence to conversations, errands, organising and workflows, with minimal to no prompting. Our first application is an agent-first mobile communication app. We believe building applications that users use daily for communication, coordination and collaboration needs will help integrate AI into their lives. The net effect is to eliminate misinformation, achieve low coordination costs, enable high quality tasks and collaboration at scale with minimal or little prompting. Role
Build and maintain production iOS applications using Swift and SwiftUI
Develop interfaces for messaging, real-time communication and AI-powered features
Integrate backend APIs, including streaming responses, asynchronous operations and error handling
Implement local storage, push notifications, background tasks and data synchronisation
Optimise application performance, startup time, memory usage and battery consumption
Implement analytics, crash reporting and monitoring to identify and resolve production issues
Work with backend, ML and design teams to develop, test and release new features
Requirements
3+ years of iOS development experience using Swift, with applications shipped to the App Store
Strong understanding of SwiftUI, UIKit, iOS SDK and application lifecycle
Experience with Swift concurrency, async/await, background processing and asynchronous data handling
Experience integrating REST APIs, managing local data and handling network failures
Understanding of iOS architecture patterns, state management and memory management
Experience profiling and optimising application performance using Xcode Instruments
Strong debugging skills and experience maintaining production iOS applications
Nice to Have
Experience building messaging, chat or real-time communication applications
Experience integrating LLM, speech, vision or other AI-powered APIs
Experience with Core ML or on-device machine learning
Experience with feature flags, remote configuration or automated iOS release pipelines
