Job description

Are you passionate about using your technical skills to make a real difference? We’re looking for an exceptional CRO Developer to join our Digital CRO & Analytics team, where your expertise will fuel charitable income growth through data-driven experimentation and impactful digital experiences.

In this role, you’ll be at the heart of a dynamic team of specialists, developers, and analysts, collaborating closely with UX/UI, Content & Journeys, Product and other partners. Together, you’ll drive our mission forward – supporting life-saving research and helping millions of hearts beat stronger for longer.

With your strong front-end development skills (HTML, CSS, JavaScript), you’ll design and implement A/B and multivariate tests that shape how people interact with our online platforms. You’ll take visual briefs, analyse requirements, build front-end experiences within our testing tools and oversee the successful launch and monitoring of each test.

 About you

As an experienced developer, you’ll deliver a spectrum of digital experiences, ranging from simple optimisations to complex, multi-page experiments. You’ll work together with UX/UI designers, bringing ideas to life while working within a design system—and always with a keen eye on accessibility and best UX practices. If you’ve previously held a design role, that’s even better!

You’ll serve as the go-to technical expert for our CRO team, translating briefs into robust solutions, meeting requirements, and providing trusted advice on feasibility, best practice, and timelines. Over time, you’ll master our testing tools, ensuring seamless test setup and rollout.

Your attention to detail and knowledge of QA means every user gets an optimal experience, regardless of device or browser. You’ll also support the wider CRO team by reviewing and troubleshooting tests, and your knowledge of custom tracking code (particularly datalayer events) will make you an indispensable part of our team.

This is your chance to help shape digital journeys that increase donations and event sign-ups, all while building your own skills and career in a supportive, purpose-led environment. If you’re ready to turn technical challenges into meaningful change, we’d love to hear from you.

Working arrangements

12-month fixed term contract from start date. Start date ASAP.

This is a hybrid role, where your work will be split between your home and at least one day per week, on average, in our London Office. This may vary from time to time, so you will need to work in a flexible way to unlock your best work for our cause.
