About The Position

Beast Industries is a multifaceted media and entertainment company founded by Jimmy Donaldson, popularly known as MrBeast, the most watched person in the world. Renowned for revolutionizing digital content creation, Beast Industries encompasses a diverse portfolio of ventures that extend far beyond its origins on YouTube. With a mission to entertain, inspire, and create significant social impact, Beast Industries operates across various domains including digital media, philanthropy, consumer products, and innovative business initiatives. At Beast Industries, we believe in the transformative power of digital media and its potential to entertain, educate, and effect positive change. Our commitment to innovation, creativity, and philanthropy drives us to explore new frontiers, create unforgettable experiences, and build a legacy that inspires future generations.

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 design backend systems the right way from the start. You're here to build the services that power consumer products at real scale, not to keep the lights on for someone else's stack.

You'll design, build, and operate the backend systems behind the MrBeast membership ecosystem: APIs, data models, and services that have to stay fast and reliable as the audience grows. That means:
Build scalable, secure backend services and APIs that support consumer products with the potential to reach 100M+ people.
Own reliability for your systems: 99.9%+ availability, low latency, and fewer customer-impacting incidents.
Use AI coding agents and modern development practices as the default, and bring AI into the systems you build where it earns its place.

Requirements

• AI-Native: You're already using AI coding agents daily to move faster, and modern development practices are your baseline.
• Typically 7+ years in software engineering with heavy backend responsibility, designing and operating distributed systems in production.
• You've led production incidents through resolution, and you design for scale and reliability with the metrics to back it up.
• You balance short-term delivery against long-term maintainability, and you take end-to-end ownership of systems and outcomes.
• Strong grasp of APIs, databases, system design, and cloud-native architectures.

Nice To Haves

• Bonus points for event-driven architectures and messaging systems, operating services in public cloud, security and data-protection best practices, and influencing technical direction across teams.

Responsibilities

• Design and implement scalable, secure, maintainable backend services and APIs.
• Lead architecture and technical design discussions for complex initiatives.
• Own service performance, reliability, availability, and operational excellence end to end.
• Partner with product, frontend, data, and infrastructure teams to ship business outcomes.
• Drive incident response, root-cause analysis, and the long-term fixes that keep issues from recurring.
• Set and improve engineering standards and patterns, and address technical debt without stalling delivery.
• Review code and mentor engineers across the org, and optimize database, service, and infra performance.

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
