• Conduct data deep dives to uncover customer behaviour, identify optimisation opportunities, and support business decisions.
• Iterate on previous experiment learnings to continuously improve customer experience and conversion performance.
• Partner closely with Product, UX, Design, Engineering and eCommerce teams to identify opportunities, prioritize experiments, and ensure successful delivery.
• Present experiment results and recommendations to stakeholders in a clear, concise, and compelling way.
