Data Modeler

Principal Data Modeller | Credit / Financial Data

Contract

Chicago | Hybrid / flexible working

This role requires a senior data modeller/architect 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:

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

THE REQUIREMENTS:

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