About the role

We are looking for a highly motivated Application Developer Intern to bridge the gap between high-performance mobile interfaces and robust, scalable backend systems. You will build cross-platform mobile experiences for iOS and Android using Flutter while contributing to a blazing-fast, asynchronous backend using FastAPI. If you are passionate about state management, real-time data streaming, cloud-native architecture on AWS, and delivering seamless native mobile experiences, we want you on our team.

What you'll do

• Mobile development: Build, test, and deploy responsive cross-platform applications to the Apple App Store (iOS) and Google Play Store (Android) using Flutter.
• Backend development: Design and implement scalable, asynchronous RESTful APIs and real-time services using FastAPI and Python.
• Real-time features: Implement live data streaming using WebSockets/SSE and manage push notification systems using Firebase Cloud Messaging (FCM).
• Performance optimisation: Offload heavy computations using Flutter Isolates and manage backend background workers for smooth user experiences.
• Cloud infrastructure: Deploy and maintain application infrastructure on AWS.
• AI integration (bonus): Collaborate on integrating LLM workflows and AI agents into the backend.

Flutter (iOS & Android) — what we're looking for

• Proven experience building and releasing Flutter apps for both iOS and Android, including app store deployment and platform-specific permissions.
• Hands-on FCM integration across foreground, background, and terminated app states on both platforms.
• Deep expertise in Riverpod for predictable, scalable state management.
• Strong understanding of app lifecycle events and efficient data mutation handling.
• Experience implementing Isolates to keep the UI thread unblocked during heavy computations.
• Experience bridging native iOS/Android code with Dart using Method Channels.
• Ability to craft smooth, highly interactive UIs using Flutter Animations.

FastAPI — what we're looking for

• Experience building CRUD APIs with Pydantic validation, pagination, filtering, sorting, OAuth2 authentication, and structured error handling.
• Strong grasp of Python's asyncio and multi-threading for concurrent request handling.
• Familiarity with background task management — FastAPI BackgroundTasks, Celery, or similar.
• Understanding of WebSockets and Server-Sent Events (SSE) for real-time protocols.

Infrastructure

• Hands-on experience (or strong interest in learning) AWS — EC2, ECS, Lambda, RDS, API Gateway, S3.

Nice to have

• Experience with LangGraph integrations and agentic LLM workflows.
• Familiarity with CI/CD pipelines for mobile (e.g., Fastlane) and backend deployments.

What you'll get

• Paid stipend
• Certificate of completion + recommendation letter
• Potential full-time conversion based on performance
• Opportunity to work with a modern tech stack spanning complex mobile UI engineering and advanced backend architecture
