You will lead the development of trading strategies aligned to buying cycles, product launches and inventory plans, ensuring that merchandising, marketing and operational teams are working towards a unified commercial objective. You’ll be responsible for understanding and influencing stock health, sell-through, stock cover, margin performance and product lifecycle, using this insight to shape promotional strategy, visual merchandising, marketing investment and customer acquisition activity.
