Our Company

At the company, 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 Rewards Tech team is growing! We’re looking for a Senior Frontend Engineer to join our team in Maidstone.

About You

• A strong senior frontend engineer, production-grade with React and TypeScript on the web
• Hands-on building and shipping mobile apps, ideally React Native across iOS and Android
• A sharp eye for UX and design: you care how a product feels, not just whether it works
• Comfortable owning end-to-end and staging test automation as part of how you ship
• Happy working across the stack, with Python a strong plus rather than a hard requirement
• 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!
