FullStack Engineer (AI Avatar)

We are looking for a Full Stack Engineer with deep experience in LLM and Avatar development.

Responsibilities:

• FullStack Architecture: Build and maintain the core platform using robust Python (FastAPI) backends and dynamic React 18+ (TypeScript) frontends.
• AI & Avatar Systems: Integrate complex generative AI pipelines (ComfyUI), ML inference, and Voice/TTS to drive the avatar's lifelike expressions, movements, and intelligence.
• Real-Time Interactions: Ensure seamless, ultra-low latency conversations using WebSockets and gRPC, while utilizing WebGL and browser APIs for high-fidelity client-side rendering.
• Cloud Infrastructure: Architect, secure, and operate a highly available, concurrent microservices ecosystem using Docker, Kubernetes, GCP, and robust databases (SQL/NoSQL).

Requirements:

• 5+ years of front-end and back-end development experience (LLM and avatar experience is a plus)
• Deep proficiency in Python (FastAPI, async programming) or React 18+ (TypeScript, modern state management, Vite/Webpack).
• Proven experience designing scalable, highly concurrent microservices
• Ability to independently design and implement responsive, cross-platform interfaces with pixel-perfect CSS/SCSS, complex animations, and browser APIs (Web Audio, Canvas).
• Experience with WebSockets and gRPC/Protobuf.
• Hands-on experience with SQL and NoSQL databases, Google Cloud Platform (GCP), and authentication platforms like Firebase.
• Strong competence in containerization and orchestration (Docker, Kubernetes), Linux administration, advanced Git workflows, and network security fundamentals (SSL/TLS).
• Ability to leverage AI coding assistants (Claude Code, Codex)
• Bachelor’s or Master’s degree in Computer Science, AI, or a related field
