Job description

Working closely with Data Owners, Information Asset Owners, subject matter experts and technical teams, you'll investigate and document critical data assets, helping to improve data quality, governance and organisational understanding.

You'll combine analytical thinking, stakeholder engagement and data management practices to help establish the foundations for effective data governance across Companies House.

As a Data Asset Manager, you will:

  • Build and maintain the Companies House data catalogue for priority data assets.
  • Create clear and accurate records covering data definitions, ownership, metadata, source systems and lineage.
  • Work with business and technical stakeholders to capture, validate and maintain information about key data assets.
  • Investigate how data is created, transformed and used across systems and services.
  • Use SQL and other analysis techniques to explore data structures, relationships and lineage.
  • Identify, document and reconcile business rules that exist across systems, processes and business areas.
  • Translate complex technical information into clear, accessible documentation for a range of audiences.
  • Support the adoption of data asset management and governance practices across the organisation.
  • Contribute to the continuous improvement of standards, processes and ways of working within the Data Management team.  

What could a typical day look like?

No two days are quite the same. One day you might be collaborating with business and technical teams to understand how critical data is created, used and maintained. The next, you could be using SQL to investigate data lineage and relationships, validating data definitions with subject matter experts, or updating metadata and lineage records to improve transparency and governance. Through your work, you'll help ensure data is accurate, understood and fit for purpose, enabling colleagues to make informed decisions with confidence.

Person specification

We're looking for someone who enjoys understanding how data works and can build strong relationships with both technical and non-technical stakeholders.

The successful candidate will have:

  • Working with data management, metadata, data governance or related disciplines.
  • Documenting data definitions, business rules, processes or information assets.
  • Gathering information from stakeholders and validating complex requirements.
  • Using SQL, or similar tools, to investigate and understand data.
  • Translating technical concepts into clear and practical documentation.
  • Managing competing priorities while maintaining a high level of accuracy and attention to detail.
  • Working collaboratively across multidisciplinary teams.

You may also have:

  • Experience working within government, the wider public sector or a regulated environment.
  • Knowledge of data governance, metadata management or data catalogue practices.
  • Awareness of data lineage, data quality and data lifecycle concepts.
  • Knowledge of recognised frameworks such as DAMA-DMBOK.
  • Relevant data, analytics or governance qualifications.
