Overview

We’re looking for a dedicated Data Modeler to join a leading organisation in the London markets. This is a hands-on contract role (not an Architect, not a Developer-who-dabbles, not a Manager-in-hiding). You’ll be laser-focused on designing and delivering enterprise-grade data models across warehouses, lakes, and vaults.

Responsibilities

You’ll be responsible for:

• Designing and developing conceptual, logical, and physical data models.
• Implementing models across RDBMS, ODS, data marts, and data lakes (SQL/NoSQL).
• Translating business needs into robust, long-term data models.
• Applying Data Vault 2.0 techniques in real-world implementations.
• Supporting metadata management, governance, and best practices with tools like Erwin or ER/Studio.

What We’re Looking For

Must-Haves

• 5+ years hands-on experience as a Data Modeler (your CV should scream “Data Modeler,” not hide it in bullet lines).
• 2+ years hands-on Data Vault modelling.
• Strong background in data warehouses, data lakes, and enterprise big data platforms in multi-data-centre contexts.
• Proficiency with metadata management and data modelling tools (Erwin, ER/Studio, or similar).

Nice-to-Haves

• ETL/Data Transformation experience – ideally Qlik Compose or AWS Glue (alternatives like DataStage, SSIS acceptable).
• Familiarity with modern dev methodologies (Agile/Scrum, TDD).
• Knowledge of testing tools, scripting, and data cleansing techniques.

Who Will Not Be Considered

• Architects (too high-level, not hands-on enough).
• Developers who only list “data modelling” as one of many tasks.
• Generalists who do “a bit of everything.”
• Candidates focused on ETL development, management, or project coordination.

This is a contract role in London’s financial markets, offering the chance to work with enterprise-scale data in a dedicated modelling capacity. If your CV shows a consistent trajectory as a Data Modeler, we’d love to see it.
