Arcade AI is hiring an AI Engineer Intern for agentic systems and 3D on a 2-month freelance mission, with a path to full-time Founding Engineer.

Role: AI Engineer Intern - Agentic Systems & 3D. Location: San Francisco & Paris, Remote / Hybrid. Contract: 2-month freelance mission with path to full-time Founding Engineer. About Arcade: Arcade is building the future of game development: instant, accessible, and magical. Its mission is to let anyone create and publish a game in seconds, with no code and no blockers. Arcade is creating a platform where game creation feels like play, where ideas become playable worlds instantly, and where AI, real-time engines, and agentic workflows make creative game building available to billions of new creators. The team is small, fast-moving, AI-native, and backed by leading minds in gaming and tech. What you'll do: This person builds the robust, scalable brains behind Arcade's automated game creation workflow. They architect and deploy advanced AI pipelines and multi-agent systems that turn prompts into fully playable 3D games. They own AI infrastructure on GCP/Vertex while working hands-on with game logic and 3D rendering engines. They will design and implement multi-agent systems that generate complete games from logic scripting to scene design; create DSL architectures to translate unstructured LLM reasoning into deterministic playable 3D environments; handle context management, multi-turn memory, and fine-tuning via Vertex AI; integrate and orchestrate Claude and Gemini for tool use and planning; deploy, manage, and scale AI applications on GCP; and connect AI outputs to real-time rendering engines. What we're looking for: Arcade is looking for someone with a proven track record building production-ready LLM and agentic applications, strong GCP/Vertex AI expertise, and experience with Three.js, WebGL, WebXR, or a willingness to dive deeply into 3D scene graphs, spatial reasoning, and game logic. They should have shipped systems with frontier models like Claude and Gemini; be skilled in context optimization, strict JSON enforcement, and function calling; use a heavily AI-augmented workflow; build fast in small teams; and be perfectly fluent in written and spoken English. What Arcade offers: A competitive freelance rate for the initial 2-month contract, a path to full-time Founding Engineer with founding team equity, a defining role in reshaping how games are built and played, extreme autonomy, and work with a fast AI-native team.
