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 Technology team is growing and we'd love you to grow with us. We're looking for a Senior Full Stack Engineer to help shape and scale our technology platform as we pursue our ambitious vision.
In this role, you'll take a leading hand in both frontend and backend systems delivering high quality development and thoughtful technical solutions across the product lifecycle. While your primary focus will be coding and architecture, you'll also support and guide other developers, helping to foster a culture of quality, curiosity, and continuous improvement.
You're a skilled individual contributor and a collaborative technical champion, someone who enjoys working closely with others to build scalable, efficient, and well crafted applications using modern frameworks and tools.
Key Responsibilities
Lead by example as a hands on developer, contributing to both front-end and back-end codebases
Shape architecture and system design for web applications, with a focus on scalability, security, and performance
Mentor and support other engineers, championing code quality through thoughtful reviews and shared best practices

Partner with UX/UI designers to bring designs to life as functional, intuitive experiences
About You
Strong expertise in JavaScript frameworks such as React, Vue.js, or Angular, with solid proficiency in HTML, CSS, and responsive design
Solid experience with Node.js, Express.js, and building RESTful APIs or microservices
Comfortable working with both SQL (PostgreSQL, MySQL) and NoSQL (MongoDB) databases
Experience integrating automated tests into CI/CD pipelines (e.g. Jenkins, CircleCI, GitLab CI) and familiarity with containerisation tools like Docker
Knowledge of CMS would be a bonus
You do your best work as part of a team and enjoy sharing knowledge as much as gaining it
You're comfortable navigating ambiguity and a fast-moving environment
Excellent written and verbal English skills
Collaborative and grounded, you value others' perspectives and create space for them
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
