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.
