The architecture should be designed to scale to 60+ characters without substantial redevelopment.\n\nAbout the Project\n\nWe are building an AI-powered interactive platform featuring intelligent 3D characters capable of real-time conversations, emotional expressions, physical movements, and dynamic interactions with users and virtual environments.\n\nOur goal is to develop a scalable character simulation system supporting dozens of unique digital characters with different appearances, behaviors, and interaction patterns.\n\nWe are looking for an experienced 3D / Game Developer who can build an initial working prototype by leveraging existing technologies, SDKs, game engines, and character animation frameworks.\n\nResponsibilities\n\nDevelop interactive 3D characters and virtual environments.\n\nIntegrate existing 3D character assets, including rigging, animations, facial expressions, and lip synchronization.\n\nImplement character movements, gestures, emotional expressions, and interactions with virtual objects.\n\nIntegrate AI-driven character actions and behavioral states.\n\nEvaluate game engines, character creation tools, animation libraries, and AI NPC SDKs.\n\nBuild reusable character components to support rapid creation of new characters.\n\nOptimize rendering and performance for web-based applications.\n\nIntegrate real-time character interactions in collaboration with AI engineers.\n\nContribute to technical architecture and prototype development.\nRequired Experience\n\n3+ years of commercial experience with Unity, Unreal Engine, Three.js, or similar 3D technologies.\n\nStrong understanding of character animation, skeletal rigs, animation state machines, and facial animation.\n\nExperience integrating third-party 3D assets and animation libraries.\n\nExperience developing interactive characters, NPCs, avatars, or simulation environments.\n\nUnderstanding of real-time rendering and performance optimization.\n\nExperience building prototypes using existing SDKs and frameworks.\n\nAbility to make pragmatic technical decisions and deliver functional prototypes within defined timelines.\nNice to Have\n\nExperience with AI-powered NPCs or conversational avatars.\n\nFamiliarity with Convai, Inworld AI, or similar solutions.\n\nExperience with Blender, Mixamo, Character Creator, or equivalent tools.\n\nFamiliarity with WebGL / WebGPU, React Three Fiber, or PlayCanvas.\n\nExperience with audio-driven facial animation and lip synchronization.\n\nExperience with multi-character simulation systems.","description_format":"text","description_chars":2844,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"Ukraine","iso":"UA","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-29T12:21:41Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring
