The role works closely with the Insights & Analysis team, business data owners, the Data Governance Consultant, Technology Operations, suppliers and the Head of Data and Technology to keep the platform reliable, bring new data into it safely and ensure the data it holds can be trusted for reporting and decision making.The platform brings together data from the banking hubs, the Post Office and community banking channels, incident and survey systems, reference data, member banks and public data sources. It was built with a delivery partner and is now moving into business-as-usual operation, and the Senior Data Engineer takes ownership of it as that transition completes, including the runbook, documentation, backlog, alerting and recovery arrangements.\nThis is a hands-on engineering role where design, build and operation sit with the post holder rather than with a supplier. The Senior Data Engineer is accountable for the platform’s data pipelines, data models, databases, APIs and Microsoft Fabric integrations, for the engineering standards that govern how they are built and released, and for reducing the organisation’s reliance on supplier-led development.\nThe role supports data quality and governance by implementing the data quality rules, critical data elements, definitions, lineage, classification, access controls and retention set through the data governance framework, so that governance is built into how data is ingested, transformed and shared. The Data Governance Consultant establishes the framework and Microsoft Purview; this role implements them in the platform.\nThe role will also help set the direction of the platform over the longer term, including new data sources and integrations, the data foundations for Finance reporting and dashboards, and the governed datasets that allow approved AI tools to be used, working with the wider Technology team, the Insights & Analysis team, Risk and relevant suppliers to prioritise the backlog.\nThe role also acts as a business partner within the IT function, working with Finance, Risk, Compliance, Projects, Change and wider business teams to make data practical, trusted and usable. It helps unblock data-related delivery issues, clarify requirements and definitions, coordinate supplier action where specialist support is used, and ensure the platform serves business outcomes without becoming a bottleneck.\nResponsibilities\nOwn the architecture, operation and reliability of the data platform, including the Azure landing zone, the Lakehouse and its Bronze, Silver and Gold layers and the development, test and production environments.\nLead the transition of the platform from the delivery partner into business-as-usual operation, completing knowledge transfer and taking ownership of the runbook, documentation, backlog, alerting, backup and recovery arrangements.\nOperate the platform day to day, including scheduling and orchestration, monitoring, incident and problem resolution and performance, so that data is available and accurate when the business needs it.\nDesign, build and maintain data pipelines for new and existing sources, including member bank and Post Office files, incident and survey systems, reference data and public APIs, replacing manual handling of Excel and CSV files.\nDesign and maintain the data models, including star schemas, source-of-truth datasets and semantic models, and build new databases, data marts and APIs that make platform data available to other systems in a controlled way.\nImplement data quality, validation and cleansing controls, applying the rules, critical data elements and definitions set through the data governance framework, so that inconsistent data is identified before it reaches reporting.\nImplement the data governance framework technically, including the integration between Microsoft Fabric and Microsoft Purview, lineage, classification and data retention, working with the Data Governance Consultant and business data owners.\nOwn the platform security model, including workspace and row-level access, the secure upload area for external partners and service principals, working with the Technology Operations Manager, the Cyber Security Manager and the MSP.\nOwn the engineering practices for the platform, including Azure DevOps source control, CI/CD and infrastructure-as-code deployments, testing, release management and the solution documentation.\nSupport the Insights & Analysis team and business data owners by prioritising the data backlog, translating business questions into trusted data, and supporting the Insights & Analysis team with their Power BI reporting built on the platform, including the foundations for Finance reporting.\nMaintain clear reporting on platform health, data quality, risks and issues for the Head of Data and Technology, and reduce key-person dependency by documenting the platform so that others can support it.\nAs the data warehouse grows there will likely be scope for a Junior Data Engineer who will report into the Senior Data Engineer.Requirements\nRole specific skillsMicrosoft Fabric data
