Software Engineer - iOS

Devsinc is looking to hire a skilled Software Engineer – iOS to build scalable, secure, and enterprise-grade mobile applications. In this role, you will develop, maintain, and optimize high-performance native iOS applications using Swift, Objective-C, Foundation Framework, UIKit, and SwiftUI.

The ideal candidate has at least 2 years of post-graduation professional experience in iOS development, with expertise in modern iOS architectures, RESTful APIs, performance optimization, and the complete application lifecycle, from development to App Store release.

Responsibilities

• Design, develop, test, deploy, and maintain high-performance native iOS applications using Swift and Objective-C, delivering scalable, secure, and production-ready solutions.
• Architect and implement robust iOS applications using MVVM, MVC, Clean Architecture, and the Coordinator Pattern, ensuring modularity, reusability, maintainability, and testability.
• Build responsive and reusable user interfaces using SwiftUI, UIKit, Auto Layout, adaptive layouts, animations, custom UI components, and design systems for seamless experiences across iPhone and iPad.
• Design and integrate scalable networking layers by consuming RESTful APIs, handling JSON serialization, OAuth/JWT authentication, pagination, error handling, retry mechanisms, and secure communication using URLSession, Combine, or Swift Concurrency (async/await).
• Implement local persistence and offline capabilities using Core Data, SQLite, UserDefaults, or similar frameworks, optimizing data synchronization, caching, and state management.
• Develop advanced mobile features including Push Notifications (APNs/FCM), Deep Linking, Universal Links, background tasks, location services, camera integration, Face ID/Touch ID, permissions handling, and Keychain storage.
• Optimize application performance by resolving issues related to memory management, concurrency, startup time, rendering, battery usage, networking, and responsiveness using Instruments, Xcode Profiler, and Debug Navigator.
• Write unit and UI tests using XCTest, contribute to CI/CD workflows, and improve application quality and release stability.
• Integrate third-party SDKs for analytics, crash reporting, authentication, payments, mapping, messaging, and other platform services while ensuring security and maintainability.
• Contribute to CI/CD pipelines, release management, code signing, provisioning profiles, TestFlight distributions, and App Store releases, following engineering best practices.

Requirements

• Bachelor's degree in CS, SE, or a related field, with a minimum of 2 years of post-graduation professional experience in native iOS development.
• Strong proficiency in Swift and Objective-C, including generics, ARC, concurrency, asynchronous programming, memory management, debugging, error handling, and performance optimization.
• Proven experience designing scalable iOS applications using MVVM, MVC, Clean Architecture, and the Coordinator Pattern, with strong knowledge of SOLID principles, dependency injection, modular architecture, reusable components, and application lifecycle management.
• Hands-on experience building responsive and reusable user interfaces using SwiftUI and UIKit, including Auto Layout, adaptive layouts, custom UI components, animations, navigation, accessibility, reusable design systems, and support for iPhone and iPad.
• Experience integrating RESTful APIs using URLSession, Combine, or Swift Concurrency, including JSON serialization, OAuth/JWT authentication, pagination, request/response lifecycle, retry mechanisms, and secure networking.
• Experience implementing local persistence and offline capabilities using Core Data, SQLite, UserDefaults, caching strategies, data synchronization, and advanced iOS features such as Push Notifications (APNs), Deep Linking, Universal Links, background tasks, Face ID/Touch ID, location services, camera integration, permissions handling, and Keychain Services.
• Strong understanding of multithreading, Grand Central Dispatch (GCD), Xcode Instruments, crash analysis, profiling, and application performance optimization.
• Proficiency with Git, Swift Package Manager (SPM) or CocoaPods, code reviews, branching strategies, Agile/Scrum workflows, and writing unit/UI tests using XCTest to ensure code quality and maintainability.
• Experience with GraphQL, Firebase (Analytics, Crashlytics, Cloud Messaging, Remote Config), and CI/CD tools such as GitHub Actions, Bitrise, or Jenkins is a plus.
• Experience with Fastlane, RxSwift, cloud platforms (AWS, Azure, or GCP), and the App Store release process (TestFlight, code signing, provisioning profiles, and release management) is a plus.
