Arcade AI

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.

The team is small, fast-moving, AI-native, and backed by leading minds in gaming and tech. What you'll do: This person joins a high-intensity 2-month sprint to make Arcade's game generation engine bulletproof. This is not traditional QA: the role tests, breaks, debugs, and stabilizes a complex system that turns prompts into fully playable 3D games, working directly with AI engineers and 3D systems. They will design aggressive testing strategies across the LLM to DSL to 3D engine pipeline; identify, reproduce, debug, and fix issues directly in the codebase; build automated test suites, validation pipelines, and regression systems; validate LLM outputs from Claude and Gemini for consistency, determinism, and correctness; stress-test multi-agent workflows; collaborate with AI and 3D engineers to diagnose and ship fixes quickly; and improve product quality while keeping speed high. What we're looking for: Arcade is looking for someone with a strong QA or engineering track record owning product reliability. The person can read and fix JavaScript, TypeScript, and Python; is obsessed with edge cases and breaking systems; has experience testing APIs, AI systems, game engines, or distributed systems; is comfortable with non-deterministic AI outputs; knows unit, integration, and end-to-end tests; moves fast under pressure; uses an AI-augmented technical workflow; and is 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 high-impact role in building a game creation system, extreme ownership, and work with a fast AI-native team.
