Job Role and Responsibilities

Key Responsibilities

• Architectural Blueprint: Design and maintain scalable, modular, and testable codebases using Clean Architecture and SOLID design principles.
• Core Feature Development: Lead by example by writing complex, high-performance features, custom widgets, and platform-specific native integrations.
• State Management & Data Flow: Implement robust state management solutions (e.g., BLoC/Cubit, Riverpod) and efficient local persistence layers.

Performance & Quality Assurance

• Performance Tuning: Monitor and optimize app rendering performance, fixing jank, reducing memory overhead, and optimizing network calls to ensure smooth 60/120 FPS frame rates.
• Code Reviews & Governance: Conduct rigorous code reviews, establish coding standards, and implement static analysis tools to maintain low technical debt.
• Testing Standards: Drive the implementation of comprehensive unit, widget, and integration testing frameworks.
• Technical Guidance: Mentor and upskill junior to mid-level mobile developers through pair programming, architectural walk-throughs, and code labs.
• Cross-Functional Synergy: Collaborate closely with Product, UI/UX, and Backend teams to scope out feature feasibility and translate product requirements into clean engineering milestones.

Required Qualifications & Technical Skills

• Experience: 6–8 years of professional software engineering experience, with at least 3–4+ years dedicated to Flutter and Dart in production environments.
• Framework Mastery: Deep understanding of the Flutter rendering pipeline, widget lifecycle, asynchronous programming, and platform channels (iOS/Android native integration).
• Architecture & Patterns: Proven experience with Clean Architecture, MVVM, BLOC and scalable folder/module structuring.
• DevOps & CI/CD: Familiarity with automated build and deployment pipelines (Fastlane, GitHub Actions, Bitrise) for Google Play and Apple App Store distribution.
• Monitoring & Tooling: Experience integrating and debugging via crash reporting and performance monitoring tools (Firebase Crashlytics, Sentry).
