• Develop curated data models in a medallion (bronze/silver/gold) architecture using Delta Lake, ensuring data quality, lineage, and reusability across analytics and AI use cases.

• Develop and optimise SQL and PySpark transformations for high-volume datasets, with strong attention to performance, cost, and reliability.

• Operationalise pipelines through Azure DevOps and/or GitHub Actions, embedding automated testing, deployment, and observability into the data delivery lifecycle.

• Implement data quality checks, monitoring, and alerting across critical data products, working with platform engineering on lineage and cataloguing (e.g., Microsoft Purview, Unity Catalog).

• Collaborate with data architects to align pipelines with the enterprise data model and governance standards, including PII handling, retention, and access controls relevant to insurance regulation.

• Work closely with analytics, actuarial, and data science teams to translate business requirements into robust data products and self-service datasets.
