Unity Developer / Interactive 3D Mascot Experience for Touchscreen Booth Device

We are looking for an experienced Unity Web developer or small Unity agency to implement an interactive 3D mascot experience for a web-based touchscreen/demo environment. The 3D mascot model and core animations will be created separately by our 3D team. The developer’s role is to integrate the provided 3D assets and animations into Unity, build the interaction logic, create the UI flow, optimize the web experience, and make sure everything works smoothly as a polished interactive demo. This is not an AI chatbot or voice assistant project. The experience is scripted, touch-based, and should feel alive through animation, interaction states, visual transitions, and simple content logic. What We Need We need a Unity Web developer/team to handle: * Unity Web / WebGL project setup * Integration of provided 3D mascot model * Integration of provided animations * Animation state logic and transitions I* dle / attract loop behavior * Touch-based topic menu * Scripted FAQ / guided answer flow * Text and visual overlays * Scripted audio playback or sound cues * Local/offline-friendly content structure where possible * Simple content update method, preferably JSON or spreadsheet export * Web performance optimization * QA, testing, and implementation support * Important 3D Asset Note *We will handle the 3D modeling and animation production separately.* However, the Unity developer/team must be experienced enough to guide the 3D asset requirements and identify potential issues early, including: * Recommended model format and export settings * Rigging/animation compatibility * Texture and material optimization * Polygon/performance limitations for WebGL * Animation naming and state requirements * File size and loading considerations * Lighting/material setup for a premium real-time look * Any technical constraints that may affect the final experience We need someone who can collaborate properly with the 3D team, not just “receive files and hope the internet forgives them.” Interaction Flow The intended experience is simple: The mascot appears in idle mode and invites visitors to interact The visitor taps one of several topic buttons The mascot reacts using the relevant animation/state A short scripted answer appears with text, visuals, and/or audio The experience suggests related next questions or returns to idle The goal is to create a smooth, polished, event-ready interaction, not a complex AI system. Out of Scope This project does not include: 3D character modeling Full animation production Open-ended AI chatbot Voice recognition Speech-to-text CRM integration Analytics dashboard Multilingual support Face recognition Personalized brochure generation Complex cinematic sequences Multiple 3D characters Full product configurator Ideal Candidate Please apply only if you have relevant experience with: Unity Web / WebGL development Interactive 3D experiences Touchscreen or web-based demo interfaces Integrating 3D characters and animation states Animation controllers and interaction logic UI overlays in Unity Web performance optimization Working with external 3D artists or animation teams Bonus experience: Booth / kiosk / trade show demos Product visualization Interactive mascots or avatars Web-based 3D demos for marketing or sales Optimizing Unity projects for browser-based deployment What to Include in Your Proposal Please include: * Relevant Unity Web / WebGL project examples * Examples involving 3D characters, animation states, or interactive avatars * Your recommended technical approach * How you would structure the content system * How you would coordinate requirements with the 3D modeling/animation team * A rough hour estimate by major work area * Key risks or dependencies * Your availability for the project timeline
