## About MindSnack MindSnack is a consumer mobile app that helps people replace mindless scrolling with short, practical learning sessions. We are early-stage, fast-moving, and product-driven. We care about shipping, not meetings. ## About the Role We're looking for a full-stack mobile developer who can take ownership of the app end to end. This is not a "React Native only" role. This is not a "worked on one screen in a big team" role. You will be responsible for: - Building the app - Launching it - Maintaining it - Fixing it when it breaks If you've never shipped a live app yourself, do not apply. ## What You Will Own (End-to-End) ### Mobile App - Build and maintain the React Native app (Expo or CLI) - Write clean, scalable code using TypeScript / JavaScript - Implement UI, navigation, state management, and app logic - Optimize performance and fix production issues ### Backend - Design and build APIs using Node.js - Work with PostgreSQL (schema design, queries, migrations) - Handle auth, data flow, and integrations ### iOS & Android - Create and manage builds using: - Xcode - Android Studio - Handle: - Certificates - Provisioning profiles - Keystores - Submit apps to: - App Store Connect - Google Play Console - Manage updates, hotfixes, and store rejections ### Production Ownership - Integrate analytics, crash reporting, and monitoring - Debug real-world production issues - Ship fixes fast without hand-holding ## Mandatory Requirements (Non-Negotiable) You must have: - Built at least one live mobile app available on App Store and/or Google Play - React Native development - Backend APIs (Node.js) - Database (PostgreSQL or similar) - App Store / Play Store submission ## Proof Required Applicants must submit: - Live App Store / Play Store link(s) - A short explanation covering: - What parts you personally built - Whether you handled store submissions - Backend stack used - One production issue you fixed yourself Applications without live links will be rejected. ## Core Tech Stack - React Native (Expo or CLI) - JavaScript (ES6+) / TypeScript - Node.js - PostgreSQL - REST APIs - Git - Expo experience ## Good to Have (Not Required) - In-app purchases / subscriptions - Firebase, Sentry, or similar tools - CI/CD basics (Fastlane, GitHub Actions) - Experience scaling an app post-launch ## What This Role Is NOT - Not a corporate role - Not a feature-only role - Not a "support someone else's architecture" job - Not a place to learn basics on the job - You are expected to already know how to ship apps. ## Why Join - Full ownership of a real consumer product - Zero bureaucracy - Fast decision-making - Direct impact on users and business - Opportunity to grow into a lead / founding engineer role as the company scales ## Who Should Apply - Builders - Startup-minded engineers - Developers who enjoy responsibility - People who don't panic when production breaks If that sounds like you, apply with your live app links.
