- Participate in code reviews, knowledge sharing, and agile ceremonies.
- Gain exposure to AEM Headless CMS as part of delivering BAU features alongside CRO work.
- Collaborate with backend developers and other teams to integrate frontend changes with existing APIs and services.
Experience you'll have

- Experience translating experimental CRO changes into production-ready features.
- Experience with AWS or other cloud platforms.
- Awareness of CRO experimentation tools such as Adobe Target.
- Understanding of web performance considerations and responsive design principles.

About us
BT Group was the world’s first telco and our heritage in the sector is unrivalled. As home to several of the UK’s most recognised and cherished brands – BT, EE, Openreach and Plusnet, we have always played a critical role in creating the future, and we have reached an inflection point in the transformation of our business.
Over the next two years, we will complete the UK’s largest and most successful digital infrastructure project – connecting more than 25 million premises to full fibre broadband. Together with our heavy investment in 5G, we play a central role in revolutionising how people connect with each other.
While we are through the most capital-intensive phase of our fibre investment, meaning we can reward our shareholders for their commitment and patience, we are absolutely focused on how we organise ourselves in the best way to serve our customers in the years to come. This includes radical simplification of systems, structures, and processes on a huge scale. Together with our application of AI and technology, we are on a path to creating the UK’s best telco, reimagining the customer experience and relationship with one of this country’s biggest infrastructure companies.
Change on the scale we will all experience in the coming years is unprecedented. BT Group is committed to being the driving force behind improving connectivity for millions and there has never been a more exciting time to join a company and leadership team with the skills, experience, creativity, and passion to take this company into a new era.

We will also offer reasonable adjustments for the selection process if required, so please do not hesitate to inform us.
