Senior Data Scientist jobs in Gatwick

You will design and build the systems that identify the signals that matter most for visibility, the retrieval and embedding architecture that feeds the models, the ranking and scoring framework that prioritises actions and the evaluation layer that measures how different LLMs behave across queries, surfaces and contexts.

You will work on real production problems rather than research-only work, owning models from first iteration through to live deployment.

You will also have the opportunity to develop your career in a dynamic part of the business, within a team that embraces diversity and personal development.

You will demonstrate resilience, accountability, flexibility, be experienced in leading others, managing significant size engagements and client relationships, driving results and managing risk.
