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

In this role you will own the frontend across our Cashback and Custard apps and websites, shipping new functionality that moves revenue, hardening our release pipeline with automated testing, and raising the bar on how our reward products look and feel.

Key Responsibilities

Ship new app functionality that moves revenue and retention, working closely with product and backend
Build and maintain automated end-to-end tests so staging is stable and releases are predictable
Raise the standard of web and app UX across both reward brands
Work full stack where it counts, partnering with our backend developers on the Python services behind the apps

About You

A strong senior frontend engineer, production-grade with React and TypeScript on the web
Minimum 6- 10 years experience.
Hands-on experience 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 do your best work as part of a team and enjoy sharing knowledge as much as gaining it
Comfortable navigating a fast-paced environment
Excellent written and verbal communication skills
A genuine desire to learn, grow, and lift others around you

What You’ll Get

Private Health Care (Bupa)
Hybrid Working (3 days in office)
Travel Insurance
Competitive Base Salary
Company Bonus Scheme
Paid for AI Subscription (Claude / ChatGPT / Gemini)
Market-Leading Training Programme
Recognition & Reward Scheme
Annual Company Conference
Regular Happy Hours & Team Lunches
Free Coffee, Drinks & Snacks
