We own the world's largest dataset of this kind, enabling field users and customers to make smarter, more efficient decisions about their assets and operations. Our purpose is to deliver transformative commercial and environmental outcomes, helping global clients across utilities, telecoms, retail and energy improve pricing accuracy, speed up delivery, ensure safety, and maintain compliance.

  • Develop and optimise inference pipelines to ensure accuracy, reliability, and consistency of outputs that meet enterprise-level standards.
  • Implement and run systematic evaluation workflows using both automated tools (e.g., DeepEval, Langfuse) and human-in-the-loop review to validate model performance and safety.
  • Support RAG or retrieval-based features where required, including working with vector databases and document-processing pipelines.
  • Collaborate with product and engineering teams to define use cases, set KPIs, and deliver AI features aligned with business goals.
  • Mentor technical/non-technical stakeholders on Gen AI capabilities, limitations, and responsible adoption.

What you’ll need:

  • Bachelor's or Master's in Computer Science, AI, Data Science, or a related technical field.
  • At least solid 2+ years of hands-on experience building and deploying LLM-based systems (e.g., fine-tuning, RAG, prompt engineering).
  • Strong proficiency in Python and hands-on experience with LLM orchestration frameworks (e.g., LangChain, CrewAI, AgnosAI or similar).
  • Experience with vector databases (e.g., Pinecone, Weaviate), retrieval optimisation (OpenSearch, FAISS, Chroma).
  • Experience using LLM evaluation tools and methodologies (e.g., DeepEval, Langfuse or equivalent) to assess model quality, reliability, and performance.
  • Strong understanding of responsible AI principles and practical experience in bias detection and model transparency.
  • Ability to communicate technical AI concepts clearly to diverse audiences.
