About The Position

We’re not hiring someone to just execute tasks. We’re looking for a Founding-level AI Full-Stack Engineer who can think like a co-founder — define the product, architect solutions, build fast, and ship impactful features from day one. You’ll work directly with the founder to shape an AI-native product from the ground up, blending strong full-stack engineering with deep AI integration.

Requirements

Strong full-stack engineering skills with the ability to independently own features from start to finish.
Proficiency in React / Next.js (or equivalent modern frontend frameworks).
Solid experience with at least one backend stack: Python, Node.js, or Go.
Real hands-on experience building AI-powered products — not just calling OpenAI APIs.
Excellent product sense and the ability to balance technical excellence with user impact.
A builder mindset who thrives in ambiguity and moves quickly.

Nice To Haves

0→1 startup experience or history of shipping independent products.
Background with consumer or subscription-based applications.
A strong public GitHub portfolio showcasing meaningful projects.
Fluent English for smooth collaboration.

Responsibilities

Own core web and app features end-to-end — from ideation to deployment and rapid iteration.
Design and build scalable full-stack architecture, including APIs, databases, and modern frontend systems.
Integrate advanced AI capabilities such as LLMs, RAG, AI agents, and intelligent workflows.
Leverage AI tools aggressively to supercharge your own development speed and quality.
Think from the user’s perspective, prioritize ruthlessly, and help evolve the product vision.
