## About the role Spawn lets anyone make multiplayer games from words. Describe the game you want, and our AI companion Savi helps build the world, rules, and interactions. Seconds later, you're playing it with friends. We're a small, senior team building a custom real-time multiplayer engine, an AI-native authoring system, and the runtime that ties creation to play together. We need someone who gets excited about the chaos of making games that didn't exist 30 seconds ago feel great to play for thousands of players. As a Game Engineer at Spawn, you'll be the bridge between what AI imagines and what humans actually want to play. One week you might be building a physics engine that adapts to whatever wild mechanics an AI just invented. The next, you're optimizing WebGL rendering for 10,000 on-screen particles because the AI decided this puzzle game needs epic visual effects. You won't be handed game designs – you'll figure out how to make anything an AI generates feel magical. ## Requirements We expect experience with: - Real-time multiplayer features (even small-scale) - Graphics programming (WebGL, Three.js, shaders) - Making games feel good (physics, animations, responsiveness) ## What we offer Apply Now
