tl;dr: We're building a 3D first-person adventure game where an AI companion is the core of the game. Think MiSide with LLMs, but truly integrated with gameplay, not just a RP chatbot.

About Us

Here at Spellbrush, we're passionate about making a good anime game.

We also happen to be the world's leading generative AI studio—we're the team behind niji・journey.

Our mission is simple: use AI to bring characters to life and push the boundaries of narrative-driven games.

What We’re Building

We’ve developed an in-house LLM storytelling system that blends AI, story, and gameplay—going far beyond shallow “chat-only” experiences.

The result is an AI companion who cooperates with you in puzzles, remembers across worlds, and changes how each chapter unfolds.

We’re looking for a strong Unity engineer who loves 3D story-driven games. You’ll join our lead Unity dev, who has spent the past 5 years building interactive anime avatars, to grow our working prototype into a full game.

About The Role

You will join a small but extremely talented team to define a new kind of video game experience. You'll work alongside top otaku minds in the industry, including the creator of Warudo and Cytoid, a Google Deepmind veteran behind Project Astra, and top-tier AI researchers.

As an early member of this team, you will have significant artistic and research freedom to shape what could become the next-generation LLM-driven storytelling experience.

Why You'll Love Working With Us

Impact and Ownership: As an early team member, you'll have the opportunity to push the boundaries of what's possible at the intersection of the AI, anime, and video game industry.

A World-Class Team: You'll work directly with some of the best AI researchers and engineers in the world in a small, mighty, and fast-paced team.

We are seeking individuals who ideally are fans of anime and the anime aesthetic. We believe in the unmatched speed of in-person collaboration.
