You’ll combine quantitative analytics with customer research and behavioural insights to develop commercially focused experimentation roadmaps. You’ll determine what should be A/B tested, what should be implemented directly, and ensure designers and developers are focused on initiatives capable of delivering measurable commercial impact. Beyond execution, you’ll play a key role in developing the company's CRO framework, maintaining the quality of client strategy, presenting findings to stakeholders, and eventually hiring and mentoring additional CRO strategists.
