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.

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.
