About the role

  • Train, fine-tune, and evaluate large-language / foundation models; apply parameter-efficient techniques, reinforcement learning, and prompt engineering.
  • Build and enhance memory and context management systems, manage embeddings and retrieval pipelines.
  • Integrate structured knowledge sources like knowledge graphs and ontologies to improve reasoning and reduce hallucinations.
  • Develop pipelines for ingesting and processing unstructured and multi-format data types, including parsing, embedding, indexing, and retrieval.
  • Optimise inference and system performance to reduce latency and increase throughput; design efficient prompt pipelines.
  • Define and implement monitoring and evaluation frameworks tracking accuracy, drift, error rates, and user satisfaction.
  • Collaborate with engineers, product managers, and UX teams to convert experiments into scalable features.
  • Stay hands-on: write code, prototype solutions, and contribute directly to implementation (including some Java).

Requirements

  • Proven experience working with large language / foundation models, including training, tuning, and applying modern GenAI techniques such as reinforcement learning, memory and context systems, retrieval augmentation, structured knowledge integration, optimisation, and evaluation.
  • Master’s degree in a relevant field required; PhD preferred.
  • Strong coding skills; Java is highly desirable.
  • Track record of delivering software features or products in a collaborative environment, ideally within a product-led organisation.
  • Passion for emerging AI technologies and ability to translate research into practice.
  • Comfortable working cross-functionally to move from prototypes to production-ready features.
