Data Scientist (Generative AI)

London, United Kingdom (Flexible hybrid working)
Permanent

ROLE SUMMARY

We are seeking a highly capable and innovative Data Scientist with specialized experience in Generative AI to join our Data Science Team. In this role, you will lead the development and deployment of enterprise-grade GenAI solutions, including LLM-based applications, prompt engineering, fine-tuning, embeddings, and retrieval-augmented generation (RAG).

The ideal candidate possesses a strong foundation in machine learning and NLP, paired with hands-on experience using modern GenAI frameworks and cloud environments.

KEY RESPONSIBILITIES

• Design & Build: Develop Generative AI solutions using Large Language Models (LLMs) across enterprise use cases such as customer service, document automation, summarization, and knowledge retrieval.
• Model Adaptation: Fine-tune and adapt foundation models using domain-specific datasets.
• Pipeline Architecture: Implement RAG pipelines, embedding models, and vector databases (e.g., FAISS, Pinecone, ChromaDB).
• Cross-Functional Collaboration: Partner with data engineers, MLOps, and product teams to build end-to-end AI applications and APIs.
• Prompt Engineering: Develop custom prompts and prompt chains utilizing frameworks like LangChain, LlamaIndex, PromptFlow, or custom code.
• Optimization & Governance: Evaluate model performance, mitigate bias, and optimize accuracy, latency, and operational cost.
• Innovation: Stay current with the latest advancements in LLMs, transformers, and GenAI system architecture.
