Job description

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.
Culture: We are seeking individuals who ideally are fans of anime and the anime aesthetic. We believe in the unmatched speed of in-person collaboration.
International Opportunities: We have primary research offices in downtown Akihabara, Tokyo, and San Francisco. Visa sponsorships are available for qualified candidates.
You may be a good fit if:
You love anime and the anime aesthetic
We are literally building an anime game, so this is a requirement!
You have independently developed a 3D narrative game in Unity
Bonus points if the game is first-person.
You're good at 3D character animation
Bonus if you have used mocap and understand the mocap workflow at a studio. Bonus for having your assets on the Unity store.
You're excited about the potential of Generative AI
You'll also be working closely along some of the best AI researchers in the world. Part of working with our team may involve looking at our latest research results, and figuring out how to best apply it into our game. You will be at the literal cutting edge of what is possible with machine learning, art, and games. Having experience working with LLMs is a plus.
You're comfortable working on small, fast-paced teams
Working here will feel very much like a small indie studio: close-knit, with high ownership and flexibility.
We also believe in the unmatched speed of in-person teams, and prefer on-site collaboration in either our primary research office in Tokyo (downtown Akihabara) or San Francisco. Visa sponsorships are available.
