Job Description

Senior Flutter Software Engineer

IDT BY INDET GROUP

• Design and build high-performance features in Flutter/Dart, while maintaining and extending the native calling stack — SIP clients, audio handling, CallKit/ConnectionService integration — in Kotlin and Swift. • Own features end-to-end within our feature-first clean architecture: Bloc/Cubit state management, repositories, immutable state, and 90%+ unit-test coverage on business logic. • Work at real scale: a melos-managed monorepo with 100+ packages, strict dependency hierarchy, code generation (freezed / json_serializable), and shared design system. • Ensure reliability of a real-time product: monitor releases with Crashlytics and analytics pipelines, investigate call-quality and stability issues, and drive performance optimization. • Contribute to the overall architecture and technical strategy of our mobile platform — from package design to migration of legacy patterns to the current architecture. • Collaborate closely with product managers, backend engineers, QA, and designers as part of a cross-functional product team. • Improve our engineering toolchain: GitHub Actions CI/CD, automated store/TestFlight releases, diff-coverage gates, and code-quality automation.

Job Requirements

  • 5+ years of experience building large-scale mobile apps, including 3+ years with Flutter.
  • Strong proficiency in Flutter/Dart with deep understanding of the ecosystem: Bloc/Cubit (or comparable state management), asynchronous programming and isolates, code generation, and dependency injection.
  • Hands-on experience with native mobile development (Kotlin/Android and/or Swift/iOS) and integrating native code with Flutter via platform channels.
  • Solid understanding of mobile architecture patterns (clean architecture, modularization), performance optimization, and security best practices.
  • Strong testing culture: unit and bloc testing with mocked collaborators, deterministic tests, working under coverage gates.
  • Experience with the full mobile app development lifecycle — from concept to production and post-release monitoring — including Git, CI/CD pipelines (e.g., GitHub Actions), code signing, and deployment automation to the App Store and Google Play.
  • English: Upper-Intermediate or higher.
