Senior Data Architect (8-month FTC)

I'm hiring a Senior BI Data Architect to join a global SaaS organisation and take ownership of a large-scale data platform transformation.

This is a hands-on architecture role sitting at the intersection of data engineering and BI - where your work will directly shape how the business uses data to make decisions.

A global technology business operating in the data and insights / research space, serving major clients worldwide and processing hundreds of millions of data points annually.

They are investing heavily in modernising their data platform and analytics capabilities, with a strong focus on performance, scalability, and self-serve analytics.

You'll take full ownership of the Databricks Lakehouse and BI architecture, leading the migration away from legacy systems while building a clean, governed and scalable platform.

This is not just a design role - you'll be deep in the detail, refactoring SQL, building pipelines, and optimising performance.

• High-impact project with visible business outcomes
• Combination of architecture + hands-on engineering
• Work on performance, scalability, and governance challenges
• Flexible, remote-friendly working
