## Description

As a Sr. Full Stack Engineer, you'll operate with autonomy in a small, fast-moving team, working directly with the CTO and founding product engineer to scale Fuser's core platform. This is a hands-on engineering role - you will spend most of your time designing, coding, and shipping features across the stack.

We've launched our public beta with a strong foundation - 100k+ lines of code, multiplayer infrastructure, a node-based canvas, and dozens of AI integrations. Now we're building toward collaboration, subgraphs, post-production, and operation nodes. You'll help ship features, shape abstractions, and keep Fuser fast, stable, and expressive for creative professionals.

What You'll Do

 * Build and ship key features across the stack with the founding team
 * Own complex systems such as multiplayer, asset pipelines, or execution flows
 * Architect clean, scalable abstractions that simplify complexity without limiting control
 * Improve performance, reliability, and developer experience
 * Help define the architecture for future AI-native UI/UX patterns
 * Collaborate tightly with design and product - we move quickly and iterate often, Frontend: React 19, React Router 7, Zustand, React Flow, Three.js
Backend: Cloudflare Workers, tRPC, Drizzle ORM, PartyKit, Durable Objects
Database & Storage: Supabase (PostgreSQL), R2
AI Integrations: 50+ APIs (OpenAI, Anthropic, Runway, FAL, and more)
