Full-Stack AI Engineer

We’re working with a specialised AI consultancy that builds real, production-grade AI solutions for enterprise clients.


Right now, they’re looking for a Full-Stack AI Engineer to help build an AI assistant for a healthcare company’s call centre - something that will actually be used day-to-day, not just a proof of concept.


What you’ll be doing

You’ll be hands-on building and shipping an AI-powered assistant, working across the full stack.


That includes:

  • Building the frontend in Next.js
  • Developing RAG-based chatbot functionality (or similar LLM-driven features)
  • Deploying and running things in AWS
  • Making sure everything works reliably in a real production environment


What they’re looking for

  • Strong experience with Next.js (this is a must)
  • You’ve already built and deployed RAG chatbots or similar AI applications
  • Solid AWS experience
  • Comfortable working across the stack and owning features end-to-end
  • Someone who’s happy working in a small, delivery-focused team


The setup

  • Start: Late April
  • Duration: 6 months initially (likely extension)
  • Workload: 20-30 hours per week
  • Fully remote


Language

  • Fluent English is essential
  • German is a nice bonus, but not required
