Full-Stack Mobile Developer (React Native + Vercel + Supabase)

Role Overview

We are looking for an experienced Full-Stack Mobile Developer to own the development, deployment, and scaling of our cross-platform mobile application. You will be responsible for building a seamless frontend mobile experience while leveraging a high-performance, serverless backend architecture.

The ideal candidate has a deep understanding of mobile state management, serverless workflows, and real-time database optimization.

Core Responsibilities

Environment Architecture: Architect, implement, and maintain robust infrastructure pipelines across distinct Local, Staging, and Production environments for both frontend mobile and serverless backend layers.

Mobile Development: Design, build, and maintain high-performance, pixel-perfect cross-platform mobile apps using React Native / Expo.

Backend & APIs: Build and deploy scalable API routes, edge functions, and backend services via Vercel.

Database & Auth: Architect and optimize our relational data model, real-time sync, and authentication workflows using Supabase (PostgreSQL).

State & Data Management: Implement efficient local caching, offline support, and state management solutions.

CI/CD & DevOps: Manage automated deployment pipelines for mobile app stores (App Store/Google Play) and serverless cloud infrastructure across environments.

Technical Requirements

Environment Management: Proven experience configuring isolated multi-environment workflows (Local/Staging/Prod) across distributed architectures—specifically aligning local development DBs/emulators, preview/staging servers, and production environments.

Frontend: 3+ years of professional experience with React Native (Expo experience preferred), JavaScript/TypeScript, and modern state management (e.g., Zustand, TanStack Query).

Backend: Strong experience with Vercel (Next.js API routes or Vercel Edge Functions) and Node.js/TypeScript.

Database: Deep knowledge of Supabase or native PostgreSQL, including Row Level Security (RLS) policies, database functions, triggers, and schema migrations across environments.

App Lifecycle: Proven experience launching, updating, and maintaining live mobile apps in production with an active user base.

Testing & Tooling: Strong understanding of automated UI testing for mobile (e.g., Maestro, Detox), Git, and modern CI/CD pipelines (e.g., GitHub Actions, EAS Build).

Nice to Haves

Familiarity with native iOS (Swift) or Android (Kotlin) development for writing custom native modules.

Experience optimizing PostgreSQL performance and monitoring slow-running queries.

Pregunta(s) de postulación:

Describe a mobile app project where you managed separate Local, Staging, and Production environments across React Native, backend services, and PostgreSQL/Supabase. What tools and processes did you use to keep environments isolated and synchronized?

How many React Native apps have you personally shipped to both the App Store and Google Play, and approximately how many active users did the largest app have?

What is the most advanced work you've done with Supabase or PostgreSQL? Please include examples involving Row Level Security (RLS), database migrations, triggers, functions, or performance optimization.

Have you built and maintained backend services using Vercel (API Routes or Edge Functions)? Describe a production system you designed, including authentication, real-time data handling, and deployment workflows.
