Our Company

At Quantum, we connect global brands with high-intent consumers. We turn intent into action and complexity into clarity.

Our Mission is clear, to help smarter, faster buying decisions. Our vision, to be the world’s most used digital comparison service, delivering value and simplicity to millions.

We drive growth through data-driven affiliate marketing built for performance from day one. Every campaign is measurable, optimised in real time, and designed to scale.

With in-house tech, full-stack analytics, and a compliance-first mindset, we give our partners an edge. We drive confident decisions and growth in regulated and high-growth sectors. We’ve helped ambitious brands grow faster, smarter, and globally.

The Role

Our Data Engineering & AI team is growing! We’re looking for a Data Architect to join our team in London.

In this role you will set the design principles for our data platform and make sure everything we build lives up to them. You’ll own the architecture of QiCore, our new data warehouse, bring acquired businesses into it cleanly and lay the foundations our AI plans depend on.

• Deep knowledge of big data platforms, ETL and ELT patterns, and data governance frameworks


• Experience consolidating acquired businesses or legacy platforms into a single data model


• High standards for quality, and the clarity to explain design trade-offs to engineers and non-technical stakeholders


• You thrive when working as part of a team


• Comfortable in a fast-paced environment


• Have excellent written and verbal English skills


• Last but not least, you’ll have no ego!
