RemoteFull time

AI Engineer (LLM Applications)

$110,000 to $135,000 USD a year

Build reliable AI systems: document extraction, classification, retrieval and agents that work on real business data.

About the role

You'll build the AI-heavy parts of ARJD projects: reading invoices and delivery notes, sorting and answering requests, searching a company's own knowledge and running multi-step agents that use a client's tools.

The bar is reliability. You'll build evaluation sets, measure accuracy and design how people review the cases the AI is unsure about.

What you'll do

  • Build LLM-powered features using the Claude, OpenAI and other model APIs
  • Design extraction, classification and retrieval pipelines for messy real-world data
  • Create evaluations and track accuracy, cost and speed
  • Build human review steps for low-confidence results
  • Keep client data secure and use only the services agreed with each client

What we're looking for

  • Experience shipping LLM applications that real users depend on
  • Strong Python or TypeScript
  • Practical experience with evals, structured output, tool use or retrieval
  • A sceptical, measurement-first approach to AI quality
