About the role

The Senior AI Engineer is a hands-on senior engineering role in the Data and AI Office, reporting to the Head of AI Engineering. The role designs, builds and operationalises secure, production-grade AI agents, Copilot extensions and reusable enterprise capabilities. The role combines the depth of an experienced AI developer with the breadth and judgement of a lead engineer and solution architect. It owns solution-level technical integrity from initial use-case exploration through architecture, development, evaluation, deployment, monitoring and continuous improvement. The role will help Haleon move from isolated AI applications towards reusable skills, plugins, MCP-enabled integrations, governed data and semantic grounding, and repeatable engineering patterns that can support multiple functions, markets and use cases.
