Full-Stack Engineer (Frontend + Backend)

As a Full-Stack Engineer, you'll own product features end-to-end across our TypeScript React frontend and Python FastAPI backend with WebSocket services, SQLAlchemy, and PostgreSQL. You'll ship reliable real-time experiences for 3D model generation, editing, history, and project workflows., * Build frontend features in React + TypeScript using shared components, Tailwind, and React Query

• Implement backend FastAPI routes and WebSocket handlers for render flows
• Design stable real-time contracts (payloads, statuses, retries, and error semantics)
• Model and optimize data flows using SQLAlchemy + PostgreSQL for schemas lifecycle
• Debug and fix cross-stack issues such as hydration errors, race conditions, and stale state sync
