Job description

WeWe are looking for a highly accountable Flutter Developer who will take ownership of cross-platform architecture across Mobile (Android/iOS), Web, and Desktop applications.

You will work in an AI-first development environment, where tools like Cursor, ChatGPT, and AI-assisted debugging are mandatory in daily workflow.

You are responsible not just for building apps — but for ensuring scalability, performance, structured architecture, release stability, and long-term maintainability.

Core Ownership

You Are Accountable For

• Cross-platform architecture stability
• State management consistency
• API integration reliability
• Performance optimization
• Version release discipline
• Preventing production-level crashes
• Maintaining UI/UX consistency across devices

If build failures, performance issues, or architectural mistakes impact delivery, it falls under your review responsibility.

Technical Responsibilities

• Develop and maintain Flutter applications for:
  • Android
  • iOS
  • Web
  • Windows/macOS (if required)
• Implement scalable project architecture
• Manage structured state management (Provider / Riverpod / Bloc or similar)
• Integrate and validate REST APIs
• Handle authentication flows
• Manage local storage and caching
• Ensure responsiveness across screen sizes
• Optimize app performance and reduce rebuild overhead
• Fix memory leaks and lifecycle issues
• Validate release builds before deployment

Web & Desktop Complexity

• Handle Flutter Web rendering issues
• Optimize performance for browser environments
• Manage responsive layouts for large screens
• Ensure cross-browser compatibility
• Address desktop input handling (keyboard/mouse events)
• Maintain consistent behavior across platforms

Operational & Delivery Responsibility

• Break down features into structured development tasks
• Provide realistic effort estimations
• Maintain clean folder structure and documentation
• Follow strict Git version control practices
• Validate builds before sharing with QA
• Support production deployment process
• Maintain release notes and change logs
• Identify architectural risks early

AI-Integrated Responsibilities

• Use AI tools (Cursor, ChatGPT, AI debugging assistants) daily
• Use AI for:
  • Widget refactoring
  • State management structuring
  • Performance optimization suggestions
  • Code review assistance
  • Bug analysis
• Improve development productivity using AI without compromising quality

AI usage is mandatory. Manual-only workflow is not acceptable.

Required Skills

• Strong knowledge of Flutter and Dart
• Experience building multi-platform apps
• Clear understanding of app architecture
• Strong knowledge of state management
• Experience integrating REST APIs
• Strong debugging skills
• Knowledge of Git workflows
• Strong understanding of UI responsiveness
• Experience using AI development tools like Cursor (Mandatory)
• Good communication skills
• Candidate must be from Kerala

Good to Have

• Firebase experience
• Experience with desktop app builds
• Knowledge of performance profiling tools
• CI/CD understanding
• Experience publishing apps to Play Store / App Store

What This Role Is Not

• Not just UI development
• Not limited to screen implementation
• Not limited to fixing small bugs

This is a multi-platform ownership role requiring structured thinking, discipline, and delivery accountability.
