Sr. Full Stack Engineer
Why You're Here
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

5+ years of experience shipping full-stack applications
-
Strong skills in React + TypeScript , with backend depth in Node, tRPC, or Cloudflare Workers
-
Understanding of distributed or real-time systems
