Full Stack Engineer, Live & Game

Job Description

The Opportunity

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 live streaming and gaming experiences that set a new bar for the industry, from the ground up for the Beast community. You'll work across the full stack, frontend and backend, to deliver features at a speed that wasn't possible before AI, and help shape a product that millions of users will experience in real time.

The Product

You'll be working, as part of a small and fast-moving team, on one of the most technically demanding parts of the product: a live and game stack where traffic is unpredictable and user expectations are unforgiving. Workloads are bursty and correlated: fan-out events drive synchronized connection storms that stress-test every layer of the stack, from load balancers to live streaming service to stateful game servers to database write throughput. That means:

• Real-time features (video playback, messaging, leaderboards, in-game interactions) that must stay correct and fast under spike-driven load. 
• A client experience that needs to feel seamless across devices, network conditions, and concurrent user spikes. 
• Code that lives in production and gets stress-tested every time a creator moment drives a traffic surge.

What You'll Do

• Build and ship live and game features across the full stack 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 deployment, using AI-facilitated QA processes and tooling to maintain high engineering quality. 
• Write clean, reliable, and performant code with a strong sense of accountability for what you ship in production. 
• Collaborate closely with your teammates, contributing to a culture of high standards, fast iteration, and continuous learning.

Who You Are

• AI-Native: You're already burning through tokens and using AI coding agents daily to move faster. 
• Full Stack Engineer: 3+ years of hands-on experience building consumer-facing products across frontend and backend, with comfort moving between client and server as the product demands. 
• Real-Time Enthusiast: You have genuine interest or experience in live streaming, gaming, or real-time systems. You understand why latency matters and you care about the user experience under load. 
• Ownership Mindset: You take pride in what you ship, follow through on production issues, and don't consider a feature done until it's running reliably in the hands of users.

Strong software engineering fundamentals with hands-on experience in at least one backend language (Node.js, Go, Java, Rust, or equivalent) and one frontend framework. Bonus points for experience with live streaming protocols (HLS, RTMP), real-time systems (websockets, messaging, leaderboards), gaming backend services, or prior work at a consumer-scale company.
