Company Overview

At IAI Solutions (https : //www.iaisolution.com/), we create innovative software solutions that transform how businesses operate. We are seeking a skilled Mobile App Developer with a passion for building robust, high-performance cross-platform applications. If you have hands-on experience in Flutter and Dart and enjoy solving complex problems in real-time audio/video scenarios, we want you on our team.

Position Summary

We are looking for a Mobile App Developer with 23 years of professional mobile app development experience - at least 12 years of which must be dedicated to Flutter and Dart for cross-platform applications. The ideal candidate will be well-versed in state management using Riverpod (or similar frameworks), comfortable integrating WebRTC for real-time audio/video, and capable of handling end-to-end mobile app lifecycles (from UI design to App Store/Play Store submission). You should enjoy working on streaming/chat-style features, be adept at managing permissions and device integration (camera, microphone), and have a keen eye for responsive UI/UX design in Flutter.

Key Responsibilities

• Develop, maintain, and optimize cross-platform mobile applications using Flutter and Dart, ensuring clean architecture and modular code.
• Implement and manage complex app state using Riverpod (e.g., StateProvider, FutureProvider, AsyncNotifier) or similar frameworks (Provider, Bloc, GetX).
• Integrate WebRTC (via flutter_webrtc) for real-time audio/video functionality, including peer-to-peer streaming, signaling (Firebase/WebSocket), and handling STUN/TURN servers.
• Build responsive, user-friendly interfaces in Flutter, designing video grids, call controls, and other UI components that adapt seamlessly across various screen sizes.
• Handle real-time UI updates for dynamic states such as mute/unmute, participant joins/leaves, and other call-related events.
• Configure and debug iOS builds in Xcode and Android builds in Android Studio, including provisioning profiles, signing certificates, and deployment pipelines.
• Manage App Store (iOS) and Play Store (Android) submission processes : prepare provisioning profiles, handle versioning, and ensure compliance with store guidelines.
• Integrate RESTful APIs and/or WebSocket connections for server communication, handling JSON payloads and ensuring efficient data parsing and error handling.
• Manage device permissions (camera, microphone, network) using packages like permission_handler, ensuring a smooth user experience and handling permission-related edge cases.
• Write unit tests and widget tests for UI components and business logic; debug cross-platform and WebRTC issues in both Xcode and Android Studio.
• Implement basic security measures and privacy compliance (e.g., encryption for media streams, GDPR/CCPA requirements) to
  
  

protect user data and adhere to regulatory standards.

• Collaborate closely with designers, backend engineers, and QA teams to define requirements, review code, and deliver end-to-end features on schedule.
• Stay updated with the latest Flutter/Dart releases, WebRTC enhancements, and mobile-app-related best practices; share knowledge and mentor junior developers as needed.
• Assist in troubleshooting live production issues, perform root-cause analysis, and release timely hotfixes or updates.
