Job Description

Flutter Mobile Developer

Only Spanish-speaking candidates will be considered

We are launching a social app and are looking for a Flutter developer who will take ownership of the entire mobile application, from backend integration to store release and ongoing product evolution.

The backend is already largely implemented, so the focus will be on efficient integration, performance, and delivering a strong user experience.

What you’ll do

• Develop and maintain the mobile application in Flutter for iOS and Android.

• Integrate existing REST APIs and work closely with the backend.

• Implement push notifications using Firebase.

• Build real-time chat features using WebSockets.

• Integrate maps: Apple Maps (iOS) and Mapbox or similar (Android).

• Implement social login (Apple, Google, etc.).

• Integrate payments with Stripe.

• Develop an admin panel and booking management system connected to the app.

• Handle app publication on the App Store and Google Play.

• Ensure app stability, performance, and a high-quality user experience.

Design & UI

We have a base design, but it needs to be refined and improved during development.

Depending on your experience with frontend/UI, this responsibility may be shared, delegated, or assumed by you directly. This aspect is important for the product’s evolution.

Requirements

• Proven experience building mobile applications with Flutter released in production.

• Strong knowledge of Dart and the Flutter ecosystem.

• Understanding of clean architecture principles, modular and scalable code.

• Experience with state management and clear separation between UI and business logic.

• Ability to build a maintainable, consistent codebase across iOS and Android.

• High level of autonomy, technical judgment, and product mindset.

What we offer

• 100% remote work.

• Flexible schedule.

• Budget to be defined based on experience, technical skills, and level of responsibility assumed.

• Contribute to a product designed to grow and evolve over time.
