We’re looking for a Senior Data Analyst to join a large-scale transformation programme within a complex enterprise environment.

This is a hands-on, analytical role where you’ll take high-level discovery outputs and turn them into clear, structured data artefacts that support migration and modernisation efforts.

The Role

You’ll act as the bridge between business, architecture, and engineering teams-owning the understanding of as-is vs to-be data landscapes and driving clarity across multiple data streams.

Expect to:

  • Review and interpret discovery & handover documentation

  • Define and build data dictionaries, logical & physical data models

  • Produce entity relationship diagrams, data flows, and mappings

  • Analyse data structures (data types, PK/FK relationships, capture methods)

  • Support migration from legacy systems into modern platforms

  • Work across a variety of data sources (spreadsheets to decommissioned systems)

  • Capture and manage requirements via Jira (user stories, tickets)

  • Collaborate closely with ETL engineers, architects, and developers

  • Engage directly with stakeholders-setting up and leading client meetings

Environment

  • Large organisation with AWS & Azure estate

  • Ongoing migration to Power Platform

  • Reporting & dashboards via Power BI

  • Some exposure to tools like Databricks beneficial

What We’re Looking For

  • Strong experience as a Data Analyst in complex environments

  • Proven ability to work independently and client-facing

  • Deep understanding of data modelling & data analysis principles

  • Experience bridging technical and non-technical teams

  • Comfortable working across multiple data streams

  • Experience alongside ETL/data engineering teams
