- Architecture: Participate in the implementation of state management best practices and modular component architecture.
- Proactive Growth: Embrace a proactive and autonomous approach to staying updated with the latest mobile trends and solving complex architectural challenges.

Required Skills & Qualifications

- React Native Expertise: Proven experience developing and deploying mobile applications using React Native and the React ecosystem.
- Core Languages: Strong proficiency in JavaScript (ES6+) or TypeScript.
- State Management: Experience with state management libraries such as Redux, MobX, or Context API.
- Native Integration: Familiarity with integrating third-party libraries, native modules, and interacting with device hardware APIs.
- Workflow Tools: Hands-on experience with Git and issue-tracking tools (preferably JIRA).
- Language: Advanced English proficiency (reading and writing).

Nice-to-have Skills:

- Native Development: Experience with native mobile languages (Swift, Objective-C, Java, or Kotlin).
- API Knowledge: Solid understanding of RESTful architecture and JSON data handling.
- App Stores: Experience with the submission and release process for the Apple App Store and Google Play Store.
