💼 The Role

We’re looking for a Full Stack Engineer with strong backend experience and an interest in AI-powered systems.

You’ll help us maintain and improve our core product, fixing bugs, refining data pipelines, optimizing APIs, and ensuring our AI features stay stable and performant.

We move fast, but we care deeply about reliability. This is a role for someone who enjoys solving practical problems, keeping systems healthy, and closing tickets that make users (and teammates) happy.


🛠 Responsibilities

  • Debug, fix, and optimize issues across the stack: from database to frontend
  • Ensure reliability and performance of integrations with AI workflows (OpenAI APIs, vector stores, etc.)
  • Contribute to and maintain the customer dashboard (Next.js + React)
  • Collaborate with the CTO and engineering team to close tickets efficiently
  • Occasionally support development of new features as the product evolves


✅ Requirements

Core Tech Stack

  • Node.js (Express.js or similar frameworks)
  • REST APIs and WebSockets
  • Postgres / Supabase
  • Next.js, React, TypeScript, Tailwind CSS
  • Git / GitHub workflows


Nice to Have

  • Experience with or curiosity about AI systems (OpenAI APIs, RAG pipelines, vector databases)
  • Familiarity with Docker and CI/CD pipelines
  • Experience with performance monitoring and logging tools


🧠 Soft Skills
  • Strong debugging and problem-solving mindset
  • Pragmatic and detail-oriented: you care about finishing and maintaining things
  • Comfortable in a fast-moving startup environment
  • Self-disciplined for remote work and willing to join periodic in-person meetups


📍 Location

Must be able to attend in-person meetups every 6–8 weeks in Northern Italy.


🎁 What We Offer
  • Real ownership in maintaining and improving a growing AI product
  • A flexible, remote-first work setup
  • Exposure to cutting-edge AI systems without the chaos of early R&D
  • A friendly, motivated team that values clarity, autonomy, and quality
