Summary

# Senior AI Engineer / Full-Stack Developer for AI Companion Game (React + Node.js) We are looking for an experienced developer to help improve our AI companion game, **Echo – AI Recovering Memory**. Our team has already built the initial version of the project, and we are now looking for developers who can contribute not only high-quality code but also creative ideas that improve the overall player experience. ## About the Project Echo is an AI-powered companion game where players interact with a cute AI character that has lost its memories. Through conversations and player actions, Echo gradually rebuilds its memories, develops a unique personality, expresses emotions, and creates a personalized experience for each player. Our goal is to build an AI character that feels alive rather than simply responding to prompts. ## Technology Stack * React * TypeScript * Node.js * AI/LLM Integration * Modern Web Technologies ## What We're Looking For We are looking for developers who can think beyond implementation. We value developers who can: * Design better user experiences. * Suggest creative UI improvements. * Improve gameplay interactions. * Propose new AI features. * Challenge existing ideas with better solutions. * Think like both an engineer and a product designer. If your contribution is only writing code from specifications, this project may not be the best fit. We are looking for people who enjoy solving product and design problems as much as technical problems. ## Responsibilities * Improve the existing codebase. * Review and enhance the application architecture. * Design better AI interaction systems. * Improve game flow and player engagement. * Suggest UI/UX improvements that make the game more enjoyable. * Build scalable and maintainable solutions. * Participate in technical discussions and propose innovative ideas. ## Ideal Experience Required: * Strong React experience * Strong Node.js experience * TypeScript * Experience building production-quality applications * Clean architecture and software design skills Preferred: * AI/LLM applications * AI agents * Memory systems * RAG or vector databases * Interactive applications or games * UI/UX design experience * Animation or game interface experience ## What Makes a Great Candidate We are especially interested in developers who naturally ask questions such as: * "How can this interaction feel more natural?" * "How can the UI make players more emotionally connected to Echo?" * "Can we simplify this workflow?" * "What feature would make this game unforgettable?" * "How can we make the AI feel more alive?" We want teammates who actively contribute ideas instead of simply implementing tasks. ## When You Apply Please include: 1. A brief introduction about yourself. 2. Links to your best projects or GitHub repositories. 3. Your experience with React, Node.js, and AI applications. 4. Two or three ideas that you believe would improve this game after reviewing the repository. 5. If you were leading this project, what would be the first improvement you would make? We are looking for long-term collaborators who are passionate about building innovative AI-powered products and enjoy turning great ideas into exceptional user experiences.
