Senior Unity Game Developer

Excel at the intersection of client engineering and cloud-driven, multiplayer systems to build the future of AI-powered storytelling games.
About StorycraftStorycraft is an AI-powered, mobile-first social sandbox where players don't just play stories—they build them. Think Minecraft meets The Sims meets Wattpad : a new genre of creative, social storytelling where AI helps players bring their imagination to life.
Backed by top-tier investors who have invested in Open AI, Unity, Supercell and others, we're building a platform that reimagines storytelling as play—combining intuitive creation tools, emotionally expressive characters, and collaborative world-building.
The RoleWe're hiring a
Senior Unity Game Developer

This is a
senior individual contributor engineering role. You'll lead through hands-on coding, collaborating closely with another senior Unity developer, backend, product, and design teams to deliver performant, testable, and maintainable features.
