Remilia Corporation is building a social platform that rejects conventional social media patterns, drawing on MMO and social-game design, and personal knowledge systems. The design problems are unusual: interfaces for a knowledge graph underneath a social network, game-derived progression and economy systems, community structures closer to guilds than feeds. You'll work on the platform's interface across web and mobile, and the surface area is wide: a rich-text editor for long-form writing, real-time chat with presence, customizable profile systems built from modular components, avatar and cosmetic customization, community spaces with their own governance and identity, progression and leaderboard systems, and an internal economy with earned and purchased goods. You'll build and maintain the design system these share, produce production-ready specs inside short development cycles, and work directly with engineering on what's feasible. Most of this has no established pattern to copy—the nearest references are game UX and pre-platform web—so the job is inventing conventions, not applying them. You have: • Portfolio demonstrating shipped digital product work • Strong fluency in Figma and component-based design systems • Strong understanding of front-end constraints and mobile-first design Bonus: game UX, social platform, or community-product experience. Us: • Competitive comp, equity and benefits • Generous PTO, health insurance, lifestyle stipends • Creative studio environment Full-time, on-site in Irvine, CA. To apply: include a portfolio of shipped work.
