About the Role

We’re looking for a Founding Full-Stack Engineer to join an early-stage, YC-backed startup building an AI-powered no-code platform. As Engineer #1, you’ll work directly with the founders to design and ship core product features that enable non-technical users to build applications seamlessly.

This is a high-impact role where you’ll own features end-to-end, shape technical decisions, and help define engineering culture from the ground up.

What You’ll Do

Build and ship full-stack features using React, TypeScript, and Node.js
Develop core platform capabilities (storage, payments, authentication, etc.)
Work closely with users to understand pain points and improve UX
Enhance AI systems, including prompt engineering and evaluation workflows
Improve system reliability and handle real-world edge cases
Design and scale backend infrastructure to support production workloads
Rapidly prototype, iterate, and refine based on feedback
Collaborate directly with founders on product and technical direction

What We’re Looking For

3+ years of full-stack engineering experience
Strong proficiency in React, TypeScript, and Node.js
Experience shipping production-ready features end-to-end
Strong ownership mindset and ability to work independently
Product-focused thinking with attention to UX and detail
Comfortable working in fast-paced, ambiguous environments

Nice to Have

Experience with AWS / backend infrastructure / scalability
Background in AI/ML systems, LLMs, or prompt engineering
Experience building developer tools, editors, or platform-level features
Startup or early-stage experience

Why Join Us

Be Engineer #1 and shape the product from day one
Work directly with experienced founders
Build cutting-edge AI-powered developer tools
High ownership and rapid career growth into leadership
Opportunity to define engineering culture and standards

Apply Now

If you’re excited about building from zero, owning impactful features, and working at the forefront of AI + no-code platforms, we’d love to hear from you.
