Write clean, maintainable, and well-documented Dart code following best practices.
Participate in technical design discussions and propose scalable solutions for features and enhancements.
Develop and maintain unit, widget, and integration tests to improve overall test coverage.
Conduct code reviews to ensure quality and share best practices within the team.
Debug and resolve production issues, optimise performance, and address regressions.
Integrate third-party SDKs and REST APIs following security and architectural standards.
Contribute to CI/CD pipeline improvements and automate release processes.
Collaborate with backend engineers on API design and system integration.
Work closely with product and design teams to translate requirements into user-friendly and high-performance interfaces.
Identify technical debt and propose practical solutions with clear impact assessment.
Requirements
Minimum 4 to 7 years of mobile development experience, with at least 2 years of hands-on Flutter development in production environments.
Strong proficiency in Flutter and Dart, including state management frameworks such as BLoC, Riverpod, or Provider, as well as navigation frameworks (GoRouter or Navigator 2.0)
Solid understanding of mobile architecture patterns such as Clean Architecture, MVVM, or layered architecture.
Experience working with real-time systems such as WebSockets, Firebase, push notifications, or location services.
Experience integrating mapping solutions such as Google Maps, Apple Maps, or Mapbox.
Familiarity with payment integrations such as Stripe, Braintree, Google Pay, or Apple Pay.
Working knowledge of iOS (Swift) and Android (Kotlin) for debugging and native module integration.
Experience writing tests across different levels, including unit, widget, and integration testing.
Familiarity with CI/CD tools such as GitHub Actions, Bitrise, or Fastlane, and app store deployment processes.
Experience with monitoring and observability tools such as Crashlytics or Firebase Performance.
Understanding of REST APIs and authentication methods such as OAuth2 and JWT.
Strong communication skills and ability to work with both technical and non-technical stakeholders.
Good to Have
Experience with Bluetooth Low Energy (BLE) integrations.
Experience in mobility, ride-sharing, or logistics platforms involving real-time systems.
Familiarity with feature flagging and controlled rollouts.
Experience with performance profiling tools such as Flutter DevTools or Xcode Instruments.
Contributions to open-source projects or personal mobile application portfolio.
Experience with offline-first architecture and local storage solutions.
