£600 p/d Outside of IR35 | 6 Months Rolling Contract



This role requires a senior data modeller to take ownership of a complex financial data domain within a global data and analytics environment focused on defining and stabilising a core credit data model used across multiple products and consumers. You’ll be expected to operate independently, make modelling decisions with incomplete information, and leave behind a clear, buildable structure for engineering teams.


This is a hands-on modelling authority position!



THE ROLE:



  • Own the conceptual → logical → physical data model for a core credit domain
  • Define and refine key entities such as issuer, instrument, rating, event, and time/history
  • Work across fragmented and under-documented data sources to establish clean, canonical definitions
  • Produce source-to-target mappings, data dictionaries, and lineage artefacts
  • Ensure models are aligned with downstream delivery (data products, feeds, APIs)
  • Partner with product, engineering, and domain stakeholders to drive decisions and resolve ambiguity
  • Set modelling standards that others can follow and build against



THE REQURIMENTS:



  • Strong experience owning enterprise data models (conceptual, logical, physical)
  • Proven background in financial services data (credit, risk, markets, or reference data)
  • Ability to work in messy environments and reverse-engineer existing data structures
  • Experience producing canonical models and governance artefacts
  • Comfortable operating independently without heavy oversight
  • Strong stakeholder engagement and ability to challenge where needed
  • Exposure to Snowflake / modern cloud data platforms
  • Experience working with data products, feeds, or APIs
  • Familiarity with Data Vault / dimensional modelling approaches
  • Experience in environments with multiple data consumers and distribution channels
