About the job
Hiring a Fullstack Engineer (React / Node) for an AI-Powered SaaS Platform



I’m building a production AI-powered SaaS platform inside Google Workspace (Google Sheets add-on) with active users and real revenue.



We’re looking for a mid-level Fullstack Engineer who is comfortable:



• Building and shipping features end-to-end (React / Next.js + Node)

• Working inside a live production system

• Debugging real-world issues

• Improving and refactoring existing code

• Working in an AI-augmented development workflow (Copilot, Cursor, etc.)



Tech stack:

Next.js, Node.js, PostgreSQL, OpenAI integrations.



This is a high-impact role working directly with a technical founder. The focus is execution, ownership, and building durable systems — not corporate process.



B2B contract. Remote-friendly. Europe time zones preferred.



If this sounds interesting — message me directly or comment below.
