Build and playtest compact games and playable scenes that test how AI systems analyze, debug, and build games.

AI companies need game developers to test AI systems on real game-development work. The project involves building compact game prototypes and playable scenes, adding realistic gameplay bugs and multi-system feature problems, and describing each request as a player, designer, or producer would.

• Set pass criteria using input sequences, expected visuals, and game states you can verify

Why this is worth your time

• Earn $25–$60 an hour equivalent, paid per accepted task
• Use your game development skills on small projects, interactive scenes, bugs, and feature implementations
• Use hands-on playtesting to check that game tasks behave consistently and can be completed
• Fully remote and flexible, no fixed shifts, no commute

Who this is for

• Have AAA, indie, solo, or serious hobby game-development experience and publicly share a portfolio, published project, game jam entry, or shipped title
• Use Unity, Godot, or Unreal at an advanced level, including debugging utilities, scene management, and editor tools
