Senior iOS Developer

We are seeking an experienced, hands-on Senior iOS Developer to design, develop, and enhance high-quality, enterprise-grade mobile applications for the iOS platform.

The ideal candidate will have strong hands-on expertise in Swift, SwiftUI/UIKit, iOS SDK, modern application architecture, security, performance optimization, testing, and CI/CD. The candidate should have a proven track record of delivering scalable, maintainable, secure, and reliable production applications.

Key Responsibilities

• Design, develop, test, deploy, and maintain enterprise-grade iOS applications using Swift, SwiftUI, UIKit, and iOS SDK.
• Develop reusable, scalable, maintainable, and testable mobile components following modern iOS development standards.
• Build intuitive and responsive user experiences supporting different device sizes, accessibility, Dynamic Type, localization, and iOS platform conventions.
• Develop and maintain applications using SwiftUI and UIKit, including interoperability between both frameworks.
• Implement complex navigation, routing, Deep Links, and Universal Links.
• Design asynchronous workflows using Swift Concurrency, including async/await, Tasks, actors, MainActor, structured concurrency, and task cancellation.
• Apply modern architecture and design patterns such as MVVM, MVC, Coordinator, Clean Architecture, dependency injection, and modular design.
• Design applications with clear separation between presentation, business/domain logic, networking, persistence, and platform services.
• Integrate applications with REST APIs, JSON-based services, and enterprise backend platforms using URLSession, Codable, or equivalent technologies.
• Build reliable networking components with authentication, authorization, error handling, pagination, retries, caching, timeouts, request cancellation, and offline support.
• Implement secure authentication and authorization, including secure management of credentials, access tokens, refresh tokens, and application sessions.
• Secure sensitive application data using iOS Keychain and appropriate encryption and data-protection practices.
• Implement local persistence and caching using Core Data, SwiftData, UserDefaults, file storage, and Keychain, based on application requirements.
• Optimize application startup time, responsiveness, memory, CPU, battery, networking, and UI rendering performance.
• Use Xcode, Instruments, Memory Graph, crash reports, logs, and telemetry to identify and resolve memory leaks, retain cycles, crashes, and performance bottlenecks.
• Troubleshoot complex production issues, perform root-cause analysis, and implement sustainable corrective solutions.
• Develop and maintain unit, integration, and UI tests using XCTest and related frameworks.
• Design testable components using dependency injection, abstractions, mocks, and separation of concerns.
• Participate in code reviews, technical design reviews, architecture discussions, and security reviews.
• Support and improve CI/CD pipelines, automated builds, testing, code-quality checks, packaging, and deployment processes.
• Manage iOS certificates, provisioning profiles, entitlements, code signing, build configurations, application identifiers, and release configurations.
• Support application distribution through development, QA, TestFlight, and App Store environments.
• Manage internal and third-party dependencies using Swift Package Manager or approved alternatives.
• Collaborate with Product, UX/UI, Backend, QA, Security, DevOps, and other engineering teams.
• Provide technical guidance and mentorship to junior and mid-level developers.
• Contribute to architecture decisions, technical documentation, coding standards, reusable frameworks/components, and long-term technical strategy.
• Own features and technical initiatives from requirements and design through implementation, production deployment, monitoring, and ongoing support.

Required Skills & Qualifications

• 7+ years of software development experience, with significant hands-on experience developing and supporting production iOS applications.
• Strong proficiency in Swift and iOS SDK.
• Strong production experience with SwiftUI and/or UIKit, including integration between SwiftUI and UIKit.
• Strong understanding of Swift concepts including protocols, generics, closures, value/reference semantics, optionals, error handling, extensions, and memory ownership.
• Strong knowledge of Swift Concurrency, including async/await, Tasks, actors, MainActor, structured concurrency, cancellation, thread safety, and race-condition prevention.
• Strong understanding of ARC, memory management, retain cycles, weak/unowned references, and application object lifecycle.
• Strong understanding of the iOS application and scene lifecycle, UI lifecycle, navigation, state management, and background/foreground behavior.
• Strong understanding of SwiftUI state and data flow and appropriate state ownership and lifecycle management.
• Experience developing complex interfaces, reusable components, and navigation flows using SwiftUI and/or UIKit.
• Experience implementing Deep Links and Universal Links.
• Strong experience integrating RESTful APIs and JSON-based backend services.
• Strong knowledge of URLSession and Codable, including authentication, error handling, retries, caching, timeout management, request cancellation, and connectivity considerations.
• Experience with Core Data, SwiftData, UserDefaults, file storage, and Keychain.
• Strong understanding of mobile application architecture, including separation of concerns, dependency injection, state management, modularization, reusable components, and testability.
• Experience with MVVM, MVC, Coordinator, Clean Architecture, or similar architectural patterns.
• Strong understanding of secure mobile application development, including Keychain, secure token storage, authentication lifecycle, encryption, network security, sensitive-data protection, and secure logging.
• Experience with OAuth 2.0 and OpenID Connect is highly desirable.
• Experience with Face ID, Touch ID, and LocalAuthentication.
• Strong experience with Xcode, XCTest, Git, Instruments, Memory Graph, crash diagnostics, and iOS debugging/profiling tools.
• Experience diagnosing and resolving memory leaks, retain cycles, crashes, threading issues, performance bottlenecks, and main-thread blocking.
• Experience developing unit, integration, and UI tests and designing applications for automated testability.
• Experience with CI/CD, automated builds, testing, application signing, certificates, provisioning, entitlements, and deployment.
• Experience with TestFlight and App Store release processes.
• Experience with Swift Package Manager and dependency management.
• Familiarity with push notifications, analytics, telemetry, crash reporting, feature flags, and application monitoring.
• Understanding of iOS accessibility, localization, Dynamic Type, privacy, and Apple platform design considerations.
• Strong production troubleshooting and root-cause analysis skills.
• Experience participating in code reviews and technical architecture/design discussions.
• Demonstrated ability to mentor developers and promote engineering best practices.
• Excellent problem-solving, ownership, communication, and cross-functional collaboration skills.

Preferred Experience

• Experience building enterprise-scale iOS applications.
• Experience working with secure and highly regulated mobile applications.
• Experience modernizing or migrating existing UIKit applications toward SwiftUI and modern Swift Concurrency.
• Experience working in Agile/Scrum development environments.
