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.
