About the Role

As Engineer #1 , you’ll work directly with the founders to build the product from the ground up and help shape the engineering culture. This is a true founding-team role with ownership across the entire stack—from AI systems to user-facing features and core infrastructure.

You’ll wear multiple hats, move quickly, and play a defining role in shaping both the product and the company.

What We’re Looking For

• 3+ years of full-stack engineering experience
• Strong experience with React, TypeScript, and Node.js
• Proven track record of shipping production features end-to-end
• High ownership mindset — you take features from idea to production
• Ability to move quickly while maintaining quality and strong engineering practices
• Strong product instincts and attention to UX and detail
• Comfortable working in a fast-moving, early-stage startup environment

About the Company

We are building an AI-first software platform designed to enable non-technical users to build and deploy full-stack web applications. The company has experienced strong early traction, scaling rapidly to hundreds of paying customers in its early stages.

Our goal: Become the default platform for building and shipping software in the AI era.

Founding Team Background:

• Former Staff Engineers from leading infrastructure and developer-platform companies
• Leadership with a proven track record of bootstrapping and scaling SaaS to multi-million-dollar ARR
