• Integrate Native Modules : Leverage Android (Kotlin / Java) and iOS (Swift) expertise to develop custom plugins and optimize performance.
• Optimize API Communication : Implement reliable data fetching and error handling using GraphQL and REST for backend integration.
• Enforce Code Excellence : Write clean, well-tested code and lead code reviews to reinforce mobile development best practices.
• Collaborate Cross-Functionally : Partner with Backend, Product, and Design teams to shape GraphQL schemas and technical roadmaps.
• Mentor & Lead : Support junior engineers by sharing expertise in architecture, Flutter patterns, and native integrations.

Requirements of the role :

• 5+ years of professional software engineering experience, including at least 3+ years in mobile development with a history of shipping and maintaining production apps
• Expert-level proficiency in Flutter and Dart
• Strong proficiency in a native mobile platform, preferably Android (Kotlin / Java), with bonus points for iOS experience (Swift / Objective-C)
• Significant hands-on experience integrating mobile apps with backend services via GraphQL (e.g., Apollo, GraphQL-Flutter), with a strong understanding of best practices.
• Experience applying modern mobile architecture patterns—such as Provider, Bloc / Cubit, Riverpod, MVVM, or Redux—to build scalable, maintainable apps. xcskxlj
