Senior Data Analyst – Data Delivery

This is a precision data delivery role — not a dashboarding or engineering position. You will own one of IWSR’s core data products end-to-end: ingesting, processing, and distributing it on a monthly cadence to senior external clients, while driving its ongoing modernisation.

If you are energised by accurate, high-stakes data work — where getting it right every time genuinely matters — this role is built for you.

Please note: if your experience is primarily in Azure Data Factory, Databricks pipelines, or Power BI dashboard development, this role is unlikely to be a strong fit

Now part of the WGSN group, we combine deep industry expertise with a fast-growing, collaborative team culture headquartered in central London.

What you’ll do

• Own and deliver a dedicated data product on a monthly cycle — from raw ingestion through to client-ready output
• Migrate Excel-based processes to SQL-based operations, dashboards, and scalable delivery frameworks
• Troubleshoot and triage data quality issues with diligence and precision
• Act as the primary point of contact for senior internal and external stakeholders on your product
• Collaborate with data scientists and senior analysts to implement data-driven solutions
• Document processes and implement best practices across the Data Delivery team
• Keep pace with advances in data processing, analytics, and AI to continuously modernise delivery
