• Build robust networking layers to integrate with REST APIs and backend services, handling authentication, error states, retries and offline scenarios.
• Implement security best practices to protect user data and credentials, including Keychain, Secure Enclave, encryption and certificate pinning.
• Implement and maintain push notifications (APNs / FCM) and background tasks.
• Collaborate with UI/UX designers, software testers, backend engineers and hardware teams to ensure app presentation and functionality meet requirements and Apple's Human Interface Guidelines.
• Write clean, testable code; review peers' code and rectify errors before app releases.
• Profile and optimize app performance, memory usage and battery consumption.
• Own and improve iOS CI/CD pipelines, code signing, provisioning profiles and TestFlight / App Store release processes.
• Monitor app reviews, crash reports and analytics to identify areas for improvement.
• Recommend and implement process and technology improvements.
• Provide training, mentorship and support to team members.

What you'll need

• Bachelor's degree in Computer Science, Engineering or a related field.
• 4+ years of experience in native iOS application development using Swift.
• Portfolio of iOS apps published on the App Store, with evidence of contributions across the full development lifecycle.
• Strong proficiency in Swift and SwiftUI, with working knowledge of UIKit and interoperability between the two.
• Practical knowledge of iOS app architecture, design, implementation and release, including MVVM, Clean Architecture and modular app design.
• Hands-on experience with RxSwift.
• Strong grasp of Swift language features, including protocols, generics, closures and higher-order functions (map, filter, reduce, compactMap).
• Dependency management with CocoaPods and Swift Package Manager, and strong troubleshooting skills for resolving dependency conflicts.
• Experience building apps that integrate with IoT devices.
• Knowledge of Bluetooth Low Energy using Core Bluetooth, including scanning, pairing, GATT services, background modes and connection reliability.
• Experience with NFC using Core NFC (tag reading/writing and NFC-based access use cases).
• Experience with Apple Wallet and PassKit, including in-app pass provisioning and mobile credential workflows.
• Solid understanding of networking: REST APIs, URLSession, asynchronous request handling, JSON parsing, authentication (OAuth, tokens) and offline storage/sync.
• Security background: Keychain, Secure Enclave, biometric authentication (Face ID / Touch ID), data encryption, certificate/SSL pinning, and awareness of OWASP Mobile Top 10.
• Good understanding of multithreading using GCD, OperationQueue and Swift Concurrency.
• Experience with background tasks and background execution modes on iOS.
• Knowledge of iOS memory management (ARC, retain cycles, weak/unowned references) and performance profiling with Instruments.
• Experience with push notifications using APNs and Firebase Cloud Messaging (FCM).
• Experience with local storage such as Core Data, Realm or SQLite.
• Familiarity with agile development techniques and CI/CD for iOS (e.g., Fastlane, GitHub Actions, Jenkins, Bitrise or Xcode Cloud), code signing and App Store Connect / TestFlight.
• Experience writing unit and UI tests using XCTest.
• Solid understanding of SDLC and agile methodologies.
• Excellent problem-solving and analytical abilities.
• Strong communication and collaboration skills.
• Ability to adapt to new technologies and learn quickly.

Nice to have
