We’re building a web-based AI app builder that lets non-technical users create, modify, and deploy real applications. At the core of the product is a browser-based IDE, powered by VS Code Web, where AI collaborates with users to write, edit, and evolve code safely.
We believe AI should feel like a partner, not a black box. That means building systems that generate understandable changes, apply them predictably, and keep users in control.
We’re hiring a Founding Full-Stack Engineer to help build the heart of the product: the AI-powered app builder and IDE experience.
This is a senior / staff-level founding role with broad scope and real product ownership. You’ll work directly with the founders to define how AI interacts with code, how changes are reviewed and applied, and how non-technical users successfully build real software.
AI is core to the product—not a feature bolted on later.
You’ll work on:
OpenBuilder is the vibe coding platform that helps non-technical builders take their ideas to production. Instead of paying for credits and getting stuck. OpenBuilder offers unlimited build credits, gets you unstuck and ready for production. It's also an open platform where you have access to all of your code from day one.

No applications, no recruiter spam. Just the intro.
A few questions to make sure this role is the right shape for you. Two minutes.
I write the intro, send it to the founder, and handle the back-and-forth.
If they’re a yes, I book the chat. You show up — that’s the whole job-hunt.
