Full Stack Engineer
MrBeast, San Mateo, CA +1
The role
We're doing an AI-first engineering rebuild for a company that already has an audience of 100M+ people. This is a zero-to-one build with no legacy constraints. You're not joining to maintain someone else's code. You're here to build the experiences that define what the Beast community can do beyond watching content, from user accounts and home page to e-commerce flows that convert at scale. You'll work across the full stack, frontend and backend, leveraging AI to ship features at a speed that wasn't possible before.
The Product
You'll be working, as part of a small and fast-moving team, on the product surfaces that every user touches: account, home page, and e-commerce. These aren't isolated features. They form the connective tissue of the entire experience, and they need to work flawlessly across a wide range of devices, network conditions, and user contexts. That means:
- 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.
