Job description

We're hiring the first dedicated AI Engineer to join a fast-growing (~280 people) Healthtech organisation making a real-world impact. This is a rare opportunity to shape the AI strategy, design production-grade systems, and bring cutting-edge LLM-powered solutions into a live product environment. The Role

You'll sit at the intersection of AI, backend engineering, and cloud systems, designing and deploying intelligent features that directly impact users.

Expect to:

  • Design and implement LLM-based applications (RAG pipelines, agents, copilots)
  • Build scalable backend services using Python and Java
  • Integrate AI into existing cloud-native SaaS platforms
  • Own the full lifecycle: experimentation ? prototyping ? production
  • Optimise model performance, cost, and latency in real-world environments
  • Collaborate across engineering, product, and data teams to identify high-impact AI use cases

Requirements

  • 5+ years in software engineering, with strong experience in Python and/or Java
  • Hands-on experience working with LLMs (prompt engineering, fine-tuning, embeddings, vector databases, RAG)
  • Experience building and deploying applications in cloud environments (Azure preferred, AWS/GCP also considered)
  • Strong understanding of APIs, microservices, and distributed systems
  • Familiarity with tools like Docker, Kubernetes, and CI/CD pipelines
  • Experience working with data stores (SQL/NoSQL) and large datasets
  • Bonus: experience with AI frameworks (LangChain, LlamaIndex, etc.)
