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 working in an agile software development team.
Experience with CSS and the DOM.
Understanding of state management patterns (e.g., Redux).
Strong collaboration skills; comfortable working across multiple teams and disciplines.
