Mobile Developer (iOS + Android)

Role Overview

You will be part of a small engineering team responsible for rebuilding the existing mobile app using modern native frameworks (SwiftUI or Kotlin/Jetpack Compose). The project includes upgrading the UI layer, replacing deprecated libraries, improving performance, and integrating with REST APIs, push notification services, and Azure-hosted backend systems.

Responsibilities

iOS (SwiftUI)

Rebuild existing Objective-C / UIKit components using SwiftUI (iOS 17+)

• Migrate networking, notifications, and background tasks to modern APIs
• Integrate with external services including Firebase, Azure API endpoints, and a custom backend queue
• Implement multilingual UI rendering and dynamic layout adjustments
• Handle offline caching, thread-safe data flows (async/await), and performance optimization
• Follow WCAG accessibility requirements (Dynamic Type, VoiceOver, color contrast)

Android (Kotlin / Jetpack Compose)

• Rewrite the existing Java 8 codebase using Kotlin + Jetpack Compose
• Replace EOL or deprecated third-party libraries with official AndroidX/Google libraries
• Implement push notifications using Firebase Cloud Messaging
• Integrate with REST APIs and Azure backend endpoints
• Build multilingual UI support with locale-specific rendering
• Ensure background delivery, Doze mode compatibility, and battery-optimized behaviors

Shared Responsibilities

Participate in code reviews and technical planning

• Work with REST/JSON APIs and authentication flows
• Implement reusable components and maintain consistent design patterns
• Write automated tests and assist with QA/debug cycles
• Document architecture, modules, and integration workflows
• Collaborate with PM and engineering lead in weekly sprints

Required Skills

For iOS Developers

4+ years of iOS development

Strong knowledge of REST APIs, error handling, and retry logic

• Ability to optimize for performance, memory usage, and battery constraints
• Experience integrating SAST/DAST feedback into code fixes
• Familiarity with GitHub Actions or CI/CD pipelines
• Understanding of accessibility best practices
• Strong communication and ability to work independently on tight timelines

Nice to Have

Experience working with multilingual or localization-heavy apps

• Azure API integration experience
• Experience with emergency/push notification–heavy apps
• Familiarity with Everbridge API (not required)
• Knowledge of Redux/Composable architecture patterns (Android) or MVVM (iOS)
