We are looking for a highly skilled and engaged Flutter Developer to play a pivotal role in the development of our flagship mobile and web video streaming application. You will be responsible for building new features, refining existing ones, and ensuring our application is robust, scalable, and a delight to use.

Project is a sports-media platform where content is curated by athletes, verified by the source. No noise. No trolls. Just real-time updates, exclusive content, and insider access—all in one place.

You will be deeply involved in architectural decisions, from managing real-time socket connections and data streams to implementing complex, animated user interactions. The ideal candidate is a problem-solver who thinks deeply about state management and isn't afraid to tackle unique challenges like low-level networking video streaming strategies.

Key Responsibilities:

* Develop and maintain high-quality, responsive, and performant features for our web, iOS and Android video streamign applications using Flutter.
* Architect and implement scalable and maintainable state management solutions using Riverpod and code generation patterns.
* Build complex, fluid, and profiessional user interfaces with custom animations, gestures, and `Hero` transitions.
* Integrate with our extensive Firebase backend, including Firestore, Firebase Auth, Cloud Functions, and Storage.
* Implement and manage features for video and audio streaming, including playback controls, background audio, and camera integration.
* Collaborate on building and maintaining a clean, testable codebase with a strong emphasis on dependency injection and separation of concerns.
* Work with GetStream to integrate live video streaming into the application.
* Troubleshoot and debug complex issues across the full technology stack, from the UI down to the networking layer.

Required Skills & Experience:

* 3+ years of professional experience building and shipping web and mobile applications with Flutter.
* Deep expertise in Riverpod for state management. You should be able to discuss the nuances of different Notifiers, using `ref.listen` for side-effects, and structuring a multi-provider architecture.
* Strong experience with the Firebase ecosystem (Auth, Firestore, Storage, Cloud Functions).
* Proven ability to implement complex and custom UI/UX, including animations, `DraggableScrollableSheet`, `BackdropFilter`, and custom `GestureDetector` logic.
* Experience with declarative navigation using `go_router`.
* Proficiency with modern Dart, including `async/await`, Streams, and code generation tools like `freezed` and `build_runner`.
* A strong understanding of clean architecture principles and a passion for writing testable code.

Nice to Have:

* Familiarity with video/audio packages like `video_player` and `just_audio`.
* Experience implementing in-app purchases (IAP), specifically with `purchases_flutter` (RevenueCat).
* Interest or experience in integrating with Generative AI platforms (e.g., Google Genkit, Firebase Vertex AI).
* A disciplined approach to testing, with experience using `flutter_test`, `mockito`, or `mocktail`.

We offer:

• Competitive salary, long-term employment;

• Honest attitude, individual approach, stability, and keeping promises;

• Flexible schedule, possibility to partially work from home or remotely;

• Personal Development Plan;

• English lessons;

• Support in the war-situation;

• Yoga classes 2 times per week;

• Personal Time Off (Kid’s activities, Car maintenance, Doctor appointment, etc.);
