Job description

Job Title: Java Developer (Mobile Apps)
Company: AppHouse Mobile Studio
Location: Mumbai, India
Experience: 3-5 years

About the Role:
We are hiring a Java Developer with a focus on native iOS mobile applications. Despite the title, this role is primarily iOS-focused — the Java refers to legacy backend context our team also maintains.

Key Responsibilities:
- Build native iOS apps using Swift and Objective-C with UIKit and SwiftUI
- Implement view controllers, tab bar navigation, modal presentations, and deep link routing
- Handle push notifications via APNs, CoreData persistence, and Keychain-based secure storage
- Integrate Sign In with Apple, OAuth 2.0 token flows, and biometric authentication
- Optimize iOS app launch time, memory footprint, and frame rate using Xcode Instruments
- Submit releases to the Apple App Store with proper code signing, provisioning profiles, and TestFlight beta rollouts
- Debug iOS-specific issues including memory retain cycles, Auto Layout constraint conflicts, and device compatibility
- Maintain a small Java Spring Boot backend that provides the iOS app's REST API endpoints

Required Qualifications:
- 3+ years building native iOS apps in Swift
- Familiarity with UIKit, SwiftUI, CoreData, and modern iOS app architecture (MVVM, Combine)
- Knowledge of Java Spring Boot for backend API integration
- Apple App Store submission and code signing experience
