Company: DGH Recruitment
Apply for the Data Analyst
Location: London
Job Description:

You will lead the structured discovery of legacy finance and matter data, assess its quality and structure, and play an instrumental role in the migration process that follows.

Responsibilities

  • Own the data discovery process across legacy finance and matter systems, profiling data volume, quality, completeness, and structure
  • Get a true understanding of legacy database schemas across practice management, case management, and finance platforms, producing field‑level mapping documentation
  • Write SQL queries to extract, profile, and validate data from source systems, turning raw data into structured discovery outputs
  • Surface data quality issues, retention risks, and anomalies early
  • Contribute to the data migration, working across extraction, transformation, validation, and post‑migration reconciliation
  • Translate complex data findings into clear, well‑structured outputs, for discovery reports or exception logs
  • Contribute to migration runbooks, test scripts, and acceptance criteria
  • Build and maintain MI dashboards

Requirements

  • At least three years in a data analyst or data migration role, with exposure to complex, multi‑system environments
  • Solid SQL capability, with the confidence to write queries against unfamiliar schemas, extract and profile data at volume
  • A proven track record in data discovery and quality assessment, with the ability to identify and categorise issues at scale and communicate findings in a way that drives action
  • Understanding of the data migration lifecycle, from extraction and transformation through to loading, reconciliation, and acceptance testing
  • Strong communication skills, with the ability to present complex data findings clearly to non‑technical audiences
  • Experience producing high‑quality data documentation, including data dictionaries, field mapping matrices, and quality exception logs
  • Resilience and resourcefulness when faced with legacy data that is incomplete, inconsistently structured, or poorly documented

What Would Set You Apart

  • Hands‑on familiarity with legal practice management or case management systems, for example Aderant Expert, SOS Connect, Partner for Windows, ProClaim, Linetime Liberate, or VisualFiles.
  • SQL skills, including the ability to interrogate unfamiliar schemas, write profiling and extraction queries, and support transformation and field‑level mapping; exposure to scripting languages such as Python for data preparation and automation
  • An appreciation of the data retention obligations and regulatory considerations that apply to legal sector data, particularly client matter records and financial information, and how these affect migration scoping and decision‑making
  • Prior experience working within a structured programme or project delivery environment, with an understanding of how data workstreams fit into a broader delivery lifecycle
