Mobile Application Engineer

As a Mobile Application Developer using Flutter, your role involves developing and enhancing cross-platform mobile trading applications. You will collaborate with product, design, and backend teams to deliver performant, secure, and user-friendly experiences for real-time market data, order placement, and portfolio management. Key Responsibilities: - Build and maintain Flutter mobile applications for iOS and Android, following clean architecture, SOLID principles, and Dart best practices. - Implement responsive UI components displaying real-time market data, charts, and interactive trading dashboards. - Integrate RESTful and WebSocket APIs to support live price feeds, trade execution, account updates, and notifications. - Collaborate with backend teams to define data contracts, ensure efficient serialization/deserialization, and handle offline caching and synchronization. - Optimize application performance by profiling Dart code, minimizing widget rebuilds, and leveraging platform channels for native integrations. - Write automated unit, widget, and integration tests to ensure reliability and prevent regressions. - Participate in UI/UX reviews, translating design mockups into pixel-perfect layouts and ensuring accessibility standards. - Monitor crash reports and user analytics, triage issues, and deliver timely fixes to maintain 99.999%+ uptime for mobile apps. Technical Requirements: - Proficiency in Flutter and Dart, with 2+ full lifecycle projects delivered to production. Knowledge of React Native, ReactJs, Frontend JS Frameworks/TypeScript will be desirable. - Strong understanding of widget composition, state management (Provider, Bloc, Riverpod), and responsive design. - Experience integrating RESTful APIs and WebSocket streams; knowledge of JSON, protobuf, or gRPC. - Familiarity with charting libraries (e.g., fl_chart), custom animations, and complex gesture handling. - Ability to implement secure storage for credentials, tokens, and sensitive user data. - Experience setting up CI/CD workflows for Flutter apps, code signing, and store submissions. Experience & Qualifications: - 46 years of mobile development experience, with at least 2 years focused on Flutter. - Previous work on trading, fintech, or real-time data applications is highly desirable. - Bachelors degree in Computer Science, Engineering, or equivalent. - Strong problem-solving skills, attention to detail, and a proactive approach to code quality. - Excellent communication skills and ability to work in agile, cross-functional teams. Performance Expectations: Deliver recent features and bug fixes in 12-week sprint cycles, maintaining high code coverage (> 80%). Ensure app crash rate remains below 1% and performance metrics (startup time, frame rendering) meet industry benchmarks. Collaborate effectively to release bimonthly updates with zero critical regressions.
