Founding Engineer Intern (Mobile/Full stack)

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.
