Fullstack React Native Developer - Full-time - LATAM

Overview

We are building an AI companion mobile app designed for adults aged 65+. The app combines voice and text interaction, daily check-ins, and family connectivity features to help seniors stay engaged, connected, and supported.

We are looking for a Fullstack React Native Developer to execute an already-designed system. The product architecture, technical specifications, and core scaffolding are already complete, so this role is focused on implementation and delivery rather than architecture or product design.

This is a short-term, full-time contract (35–40 hrs/week) for approximately 4–6 weeks, with potential for ongoing part-time maintenance work after launch and possible involvement in a second mobile application.

Responsibilities

• Implement mobile application features using the existing technical specifications and architecture
• Build and maintain the app using React Native with Expo and TypeScript
• Integrate backend services using Firebase (Auth, Firestore, Cloud Functions, Storage)
• Implement secure API integrations using provided keys
• Configure and manage Firestore security roles
• Implement push notifications using Expo
• Integrate RevenueCat for subscriptions
• Support voice-related integrations (e.g., ElevenLabs where applicable)
• Prepare and execute builds using Expo Application Services (EAS)
• Manage and complete App Store and Google Play submissions
• Collaborate with the team to ensure successful product launch
• Focus on execution and deployment rather than system redesign
