My client is a fast-growing AI technology company building intelligent systems deployed in real-world, safety-critical environments. Their solutions combine advanced AI, data, and edge technologies to support decision-making and reduce risk in high-hazard industrial settings.

They are now looking to hire a Senior LLM Engineer to help design and deliver large language model powered capabilities across internal platforms and customer-facing products. This is a hands-on, production-focused role for someone with strong real-world LLM experience, not a purely research or experimental background.

The Role

  • Design, build and deploy LLM-driven features into live products and platforms
  • Work with both commercial and open-source LLMs, selecting the right model for each use case
  • Build and optimise RAG pipelines, embeddings and vector-based retrieval solutions
  • Develop APIs and services that integrate LLMs with existing AI, data and platform systems
  • Optimise solutions for performance, reliability, latency and cost
  • Collaborate with engineering, AI and product teams to identify and deliver high-value use cases
  • Ensure all solutions meet security, compliance and data governance standards

What My Client Is Looking For

Essential

  • Proven experience deploying LLMs in production
  • Strong Python development skills
  • Hands-on experience with:
  • Prompt engineering and evaluation
  • Retrieval-Augmented Generation (RAG)
  • Embeddings and vector databases (e.g. FAISS, Pinecone, Weaviate, Chroma)
  • Experience building LLM-backed services using FastAPI / Flask or similar
  • Strong understanding of trade-offs around accuracy, latency, cost and scalability
  • Highly Desirable

    • Experience working with or fine-tuning open-source LLMs
    • Familiarity with LLMOps (monitoring, evaluation, guardrails, versioning)
    • Experience integrating LLMs into complex or data-heavy systems
    • Docker and Linux experience
    • Background in regulated, industrial or safety-critical environments

    The Right Mindset

    • Pragmatic, delivery-focused and comfortable working with ambiguity
    • Able to translate complex AI concepts into practical solutions
    • Confident owning problems end-to-end, from idea through to deployment
    • Motivated by building AI that has real-world impact

    Why Apply?

    • High-impact role with real ownership
    • Opportunity to shape how LLMs are used in production environments
    • Work on meaningful, technically challenging problems
    • Collaborative engineering culture within a scaling business
