Senior Frontend Engineer

MrBeast • San Francisco, CA

About The Position

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, so you get to define a modern frontend stack from scratch instead of inheriting a tangle of old code. You're here to build customer-facing experiences that millions of people actually use. You'll design, build, and evolve the user-facing applications at the center of the MrBeast membership ecosystem. The work is fast and AI-first, in close partnership with product and design.

Requirements

• AI-Native: You're already using AI coding agents daily to multiply your output, and modern tooling is second nature.
• Deep Frontend Builder: Typically 8+ years in software engineering with serious frontend depth, building modern web apps in JavaScript and TypeScript and maintaining scalable architectures in production.
• Performance Minded: You have a real command of performance optimization, testing strategy, accessibility, and web standards, and you can prove the wins with metrics.
• Owner: You take a problem from design through production support, and you raise the bar for the engineers around you.

Nice To Haves

• Building and maintaining design systems
• Modern frameworks like React, Vue, or Angular
• Cloud-native environments and CI/CD
• A track record of leading technical initiatives across teams.

Responsibilities

• Build scalable, performant frontend architectures and reusable components for consumer apps with the potential to reach 100M+ people.
• Make core user journeys fast: page-load times and frontend latency are numbers you own and move.
• Use AI coding agents and modern tooling as the baseline for how you ship, not the exception.
• Design and implement scalable frontend architectures for complex web applications.
• Build and maintain reusable UI components and design-system integrations that other engineers ship on.
• Partner with product managers and designers to turn requirements into clean, high-quality experiences.
• Lead technical design discussions and own architectural decisions within your domain.
• Optimize for performance, accessibility, responsiveness, and usability across core flows.
• Set and enforce frontend standards and patterns, and drive their adoption across teams.
• Mentor engineers through code reviews and technical guidance, and resolve the gnarly production issues.

Benefits

• Highly competitive equity package designed for a foundational hire.
• Competitive Salary
• Generous Medical (Blue Cross Blue Shield), Dental, Vision and company-paid Life Insurance
• Company contributions to employee Health Savings Accounts (HSA)
• 401k Plan with Safe Harbor company-matching
• Flexible vacation policy and paid company holidays
• Company-provided technology package
• Relocation assistance where applicable, including travel and company-provided housing for the first 90 days
