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.

About The Role At MrBeast, we build global digital experiences that bring together content, commerce, community, and interactive entertainment. We're launching mobile competitions at a scale no one has attempted — imagine a million players competing in a live elimination bracket where one winner takes the prize. Nothing about that works unless every player trusts the game is fair.

We're looking for a Senior Game Security & Integrity Engineer to own that trust. You'll protect our games, players, tournaments, prize economies, and supporting infrastructure from cheating, fraud, abuse, and exploitation. This is a hands-on builder role: secure game and tournament architecture, automated detection at massive scale, and rapid response when adversaries adapt.

You'll partner with gameplay, platform, mobile, data, fraud, and security teams to design protections across mobile clients, backend services, APIs, and real-time telemetry — and you'll help set the integrity foundation for prize competitions watched by hundreds of millions of people.

If you enjoy adversarial problems where the attacker has real money on the line, this role is for you. What You'll Do Tournament & Competition Integrity Design the integrity architecture for large-scale synchronous competitions: server-authoritative scoring, verifiable game outcomes, and tamper-evident result pipelines. Detect and prevent score injection, result forgery, replay attacks, and clock/latency manipulation in real-time brackets. Build defenses against multi-accounting, collusion, account sharing, and Sybil attacks on qualification and elimination rounds.

Define fairness controls for prize-bearing events, including anomaly review workflows before payouts are released.

Mobile Game Security & Anti-Cheat Design client-side and server-side controls to detect bots, automation, input replay, memory manipulation, code injection, and modified or repackaged app clients. Implement and operate device attestation (Apple App Attest / Device Check, Google Play Integrity), root/jailbreak detection, emulator detection, and device fingerprinting. Evaluate and integrate commercial mobile app-hardening / RASP and anti-cheat capabilities where appropriate. Server-Side Integrity Partner with gameplay engineers to make server-authoritative validation the default for critical game logic, scoring, and transactions.

Review APIs, Web Socket services, and real-time protocols for tampering, replay, authorization, and abuse risks. Develop reusable security controls for rate limiting, session integrity, and transaction validation. Fraud & Abuse Prevention Build systems to detect account takeover, payment and payout fraud, chargeback abuse, account farming, promotion abuse, and virtual-asset laundering. Protect prize disbursement: eligibility verification, geo/age restrictions on prize competitions, and coordination with KYC and payments teams on winner payouts.

Collaborate with fraud, finance, legal, data, and player-support teams to investigate coordinated abuse and reduce losses. Translate abuse patterns into durable product controls and detection logic. Telemetry & Detection Engineering Develop security services, automation, and internal tooling (Python and/or Type Script). Build…
