About the Role

They will act as a consultant to the Clinical Solutions (CS) team, partnering on various diverse use cases and assessing the right technical fit for each use case — whether an AI‑tool‑based solution (e.g., Claude, Chat GPT) or a more traditional pipeline‑based approach best fits the requirements, cost, and scale involved. They will be responsible for building, testing, and maintaining our Generative AI, Retrieval Augmented Generation (RAG) and Natural Language Processing (NLP) solutions. This includes evaluating their performance and implementing guardrails to ensure ethical and responsible use of AI technologies. They will engage in the entire life cycle of data science projects, including design, implementation, evaluation, productionisation and ongoing enhancement.

A key focus of the work will be on the customization and optimisation of existing RAG pipelines to support applications that involve content ingestion, machine translation, and contextualised information retrieval. Experience with end‑to‑end model deployment, including leveraging AI agents, Model Context Protocol (MCP) for effective context management, and cloud platforms such as AWS (including AWS Bedrock), Azure, or similar services, is a strong plus. Their deliverables will include efficient, production‑ready Python code, with experience in Java considered an asset. They will collaborate closely with Subject Matter Experts (SMEs) and the technology team to deploy and operationalise our data science pipelines.

Requirements

5+ years of relevant applied experience in data science, with a focus on Generative AI, NLP, and machine learning. Proficiency in Python for advanced data analysis, model development, and deployment. Strong experience with transformer models and fine‑tuning techniques for large language models (LLMs). Proficiency in Generative AI technologies, including utilizing LLMs via API access, LLM evaluation tools, and prompt engineering. Knowledge of various RAG pipelines and their practical implementation.
