  • Build autonomous AI agents capable of reasoning, planning and executing complex workflows.
  • Develop multi-agent orchestration, tool integration and advanced retrieval strategies.
  • Optimise LLM performance through prompt engineering, fine-tuning and evaluation.
  • Work with Platform Engineering to deploy scalable AI services using Microsoft Azure.
  • Mentor engineers and contribute to AI architecture and engineering best practices.

What You'll Bring

  • Strong Python development experience building production AI applications.
  • Proven experience developing Agentic AI, LLM and RAG solutions.
  • Experience with frameworks such as LangGraph, LangChain, Semantic Kernel, AutoGen or similar.
  • Experience with Microsoft Azure, including Azure AI Foundry, Azure OpenAI Service and Azure AI Search.
  • Understanding of LLM evaluation, AI safety, observability and production deployment.

Why Join?

  • Build cutting-edge AI products for a global SaaS customer base.
  • Shape the future direction of Agentic AI within an ambitious technology organisation.
  • Work alongside talented engineers using the latest AI technologies.
  • Join a collaborative team with genuine ownership and impact.
