# Full Stack Engineer, App Framework & E-Commerce

- **Company:** MrBeastYoutube, LLC
- **Location:** San Francisco, CA, United States
- **Experience:** Experienced
- **Contract:** Permanent contract
- **Skills:** Artificial Intelligence, Swift (Programming Language), Backend, Kotlin, React Native, Front End Software Development
- **Published:** September 4, 2026
- **Apply:** https://startup.jobs/full-stack-engineer-app-framework-e-commerce-mrbeast-8771906

## About the Role

* AI-Native: You're already burning through tokens and running coding agents daily to multiply your output.
 * Full Stack Engineer: 3+ years of hands-on experience building consumer-facing products across frontend and backend, with a strong eye for design principles and user experience.
 * Performance Obsessed: You notice when something feels slow, you know how to find the bottleneck, and you have a track record of moving the numbers - crash rates, render latency, load times, checkout conversion.
 * Product Minded: You care about why you're building something, not just how. You use data and A/B experiment results to inform your decisions and push back when the approach doesn't make sense.

Hands-on experience with at least one mobile or frontend framework (React Native, Swift, Kotlin, or equivalent) and one backend language. Bonus points for e-commerce or marketplace experience, familiarity with modern AI coding tools and AI-facilitated development processes, and prior work at a consumer-scale company.

## Description

* User-facing surfaces (account flows, home page, checkout, and purchase experiences) that must be fast, reliable, and conversion-optimized across devices.
 * A frontend that feels seamless whether a user is on a flagship iPhone or a mid-range Android on a slow network.
 * An e-commerce flow where performance directly impacts revenue: every second of load time and every friction point in checkout has a measurable cost.

What You'll Do

 * Build and ship user-facing features across account, home page, and e-commerce surfaces using AI coding tools, contributing to a velocity that redefines what a small engineering team can deliver.
 * Take ownership of your features end to end, from development through release, using AI-facilitated QA processes and tooling to maintain high engineering quality.
 * Care about performance - page load times, checkout conversion, crash rates, and render latency are numbers you track and actively work to improve.
 * Collaborate closely with your teammates, contributing to a culture of high standards, fast iteration, and continuous learning.
