Junior Data Analyst

Analytics / BI Developer 

The Analytics / BI Developer delivers the reporting the business relies on and builds and maintains the data layer underneath it. The role combines report and dashboard delivery with hands-on data engineering across the data warehouse and ETL estate, working within established design patterns. 

Mission 

• Build, maintain and improve reports and dashboards for business stakeholders, delivering output that is accurate, consistent, and on time. 

• Understand reporting requests properly before building, clarifying the underlying business question and challenging requirements where needed. 

• Own the quality of the reporting delivered, including consistent definitions and metrics across reports. 

• Develop and maintain the reporting layer of the data warehouse, including the views, data models and data preparation that reports depend on. 

• Monitor ETL pipelines and warehouse loads, and troubleshoot and resolve pipeline failures and data issues, escalating where the cause falls outside established patterns. 

• Make routine changes to ETL pipelines and the data warehouse, such as new fields, extended loads and new tables, following established design patterns and within the change authority granted. 

• Identify data quality issues early, and resolve or escalate them before they reach the business. 

• Document reports, data models, pipelines and changes as part of everyday work, reducing single-person dependency on the data estate. 

• Provide day-to-day technical guidance and mentorship to the Junior Data Analyst. 

• Engage directly with internal stakeholders on reporting needs, and with vendors and suppliers where a data or reporting requirement calls for it. 

• Develop over time from report delivery into interpretation and insight: investigating why results move, identifying trends and raising findings. 

Outcomes 

• Reporting delivered reliably, accurately and on time, with consistent definitions across reports. 

• Reporting requests understood properly before work begins, reducing rework. 

• Data issues identified early and resolved or escalated before they reach the business. 

• A reporting layer that makes new reports faster and more reliable to build. 

• Routine ETL support and change handled within the team, reducing dependency on the Head of Analytics & Business Enablement. 

• Changes made safely and within the change authority granted, with no unreviewed changes to production. 

• A data estate that is better documented over time. 

• Continuity of reporting delivery during any absence of the Senior Reporting and Data Analyst. 

• A Junior Data Analyst who grows in capability and independence. 


• Demonstrable progression from report delivery towards engineering and insight, with change authority widening as trust is established. 

Qualifications 

• Degree, diploma or equivalent qualification in computer science, information systems, statistics, mathematics or similar, or equivalent relevant experience. 

• Two to three years of experience across reporting, analytics and data engineering. 

• Strong SQL, including complex queries, views, stored procedures and performance tuning. 

• Hands-on experience with an ETL or orchestration tool, ideally Azure Data Factory. 

• Hands-on experience building reports and dashboards in a mainstream BI tool. 

• Understanding of data warehouse modelling concepts, including dimensional models. 


• Experience with Exasol, Yellowfin BI, SQL Server, Azure Logic Apps or the wider Azure data stack is advantageous. 


• Ability to work within an existing architecture and follow established patterns. 

• Good written and verbal communication, with the ability to work with both technical and non-technical stakeholders.
