We are working with a leading online scheduling platform designed to simplify the process of coordinating meetings and events. Founded over 18 years ago, it helps individuals and teams avoid the "back-and-forth" of email scheduling by allowing users to propose multiple time slots and let participants vote on their availability.

Responsibilities of the role:

• Develop Cross-Platform Features : Build and maintain high-performance mobile features using Flutter and Dart for seamless iOS and Android experiences.
• 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.
• Proficiency with state management, dependency injection, performance profiling, and writing comprehensive unit and widget tests in Flutter.
