Why You're HereAs 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
What You'll Bring- 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
- Experience designing APIs, databases, and data flows
- Curiosity about creative tools, design systems, or AI interfaces
- A builder mindset - you enjoy coding daily and owning your work end-to-end
