A Local Government body in London is seeking a contract Data Architect to support a high-profile planning transformation programme.

  • Identify opportunities for process or data improvements across business functions.

Essential Skills & Experience:

  • Proven ability to reverse engineer data models from legacy systems.

  • Strong experience in data modelling (dimensional, relational, data vault, etc.).

  • Deep understanding of OLTP systems and transactional data environments.

  • Experience with system/data integration, data lineage, and flow mapping.

  • Comfortable translating complex technical detail into plain English.

  • Strong stakeholder engagement skills, particularly with non-technical users.

  • Ability to operate independently in a multidisciplinary agile team.

Desirable:

  • Experience with IDOX Uniform or similar Local Government planning systems.
