Business Intelligence Data Engineer

Job Description

Reporting to the Senior Business Analyst - IT, this role is responsible for translating agreed design patterns and business requirements into scalable, high-quality data models that support consistent, trusted reporting and analytics across the business. As the organisation continues to mature its data and analytics capability, this position will support the development of a governed semantic layer that provides reusable, conformed data structures across reporting domains. Working closely with the BI Data team, the role operates within established semantic modelling standards and architectural direction.

• Implement transformation logic from ingestion (Bronze/Silver) into curated Gold-layer semantic structures.
• Ensure correct grain, referential integrity, and conformance across shared dimensions.
• Support integration of new data domains into the existing semantic framework.

Azure Data Platform Development

• Develop and maintain Azure Data Factory (ADF) pipelines in line with established ingestion and transformation patterns.
• Work within the existing Azure Data Lake structure, including partitioning and incremental load strategies.

• Assist in managing ingestion from structured databases and enterprise applications via APIs.

API & Data Integration

• Implement ingestion logic for REST/JSON-based APIs, including authentication, pagination, incremental extraction, and error handling.
• Transform structured and semi-structured data into dimensional models aligned to agreed standards.
• Conduct impact analysis when upstream systems change.

Measure & Model Development

• Develop DAX measures and calculation logic aligned with defined business definitions.
• Optimise semantic models for performance and scalability in Power BI.
• Support report developers by providing well-structured and documented semantic artefacts.
