As a Software Engineering Specialist, you will play a key role in delivering features that directly improve the conversion rate optimisation (CRO) of the BT Business Broadband website, turning more visitors into customers. You’ll work closely with our CRO specialists, who run targeted experiments and identify winning tests, and you will be responsible for implementing those winning changes into our core codebase so they go live for all customers. This role is primarily focused on frontend feature delivery in our modern React-based stack, with opportunities to expand into broader business-as-usual (BAU) development once you’ve mastered the codebase.

Experience with CSS and the DOM
Understanding of state management patterns (e.g., Redux)
Strong collaboration skills

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
