Join Our Team
Join our team and help build our two engines and three product lines.
Why join us
Small team, serious ambition. Here's what you get when you build with us.
Daily use of Copilot, Cursor and Claude Code — we build with AI, not around it.
Ship products in EN / JA / ZH simultaneously, for players around the world.
Work across AI-driven games and the tools that make them — no silos.
Work is based at our Tokyo office. Key roles are on-site to keep communication tight and delivery focused.
Small team, flat structure. You decide, you ship, you iterate.
Models, conferences, hardware — we invest in people who invest in themselves.

Our culture
A hybrid Tokyo HQ, quiet deep-work spaces, and a rooftop for the long talks. We care about craft, honesty, and shipping things we're proud of.
No fake perks, no meeting theatre — just engineers, designers and operators working alongside AI to make better games and better tools.
