• 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

Core Technical Requirements

• 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

Level Expectations SDE III

• Typically 6 to 9 years of iOS development experience
