• Build responsive and reusable user interfaces using SwiftUI and UIKit

• Own features from technical design and development through release and post-production monitoring

• Collaborate closely with Product, Design, Backend, AI, Security, and Quality Engineering teams

• Integrate REST APIs, WebSockets, push notifications, analytics, authentication systems, and third-party services

• Improve application start-up time, rendering performance, memory usage, battery consumption, and crash rates

• Develop reliable offline experiences using local storage, caching, and data synchronisation

• Write modular, testable, and maintainable code using established architectural patterns

• Participate in code reviews, architecture discussions, sprint planning, and production troubleshooting

• Monitor application health using crash reporting, analytics, logging, and performance-monitoring tools

• Maintain security standards for user data, API communication, local storage, and application releases

• Support CI/CD pipelines, automated testing, TestFlight distribution, App Store releases, phased rollouts, and production monitoring

• Strong proficiency in Swift and the iOS SDK

• Hands-on experience with SwiftUI and UIKit

• Strong understanding of Swift Concurrency, async/await, actors, Combine, and asynchronous programming

• Experience with MVVM, VIPER, Clean Architecture, The Composable Architecture, or similar scalable architectural approaches

• Strong understanding of the iOS application lifecycle, memory management, multithreading, networking, and performance optimisation

• Experience with URLSession, Codable, Core Data, UserDefaults, Keychain, and local caching

• Experience integrating REST APIs, WebSockets, Firebase, push notifications, universal links, and deep links

• Knowledge of dependency injection, modular architecture, background processing, pagination, and data synchronisation

• Experience writing unit and UI tests using XCTest, XCUITest, or Swift Testing

• Familiarity with Git, Swift Package Manager, CocoaPods, CI/CD pipelines, App Store Connect, TestFlight, and production debugging

• Good understanding of Apple’s Human Interface Guidelines and the ability to translate Figma designs into polished iOS experiences
