The Role

·Create benchmarks and reusable insight frameworks to guide both internal strategy and client-facing work

·Spot monetisable opportunities in our data that could become new tools, models, or products

3. Power AI-Driven Tools

·Train and fine-tune AI models using cleaned internal data

·Connect data pipelines to AI tools to deliver more useful, context-aware outputs

·Ensure models are maintained, explainable and delivering consistent value over time

4. Safeguard Trust & Communicate Clearly

·Monitor for bias, drift or errors in AI outputs and ensure compliance with legal and ethical standards

·Translate technical findings into clear, business-focused recommendations for internal stakeholders

·Experience building centralised data platforms, pipelines, and models from the ground up

·Familiarity with tools like SQL, Python, dbt, Airflow, Spark, and modern cloud environments
