• Managing the sample process by chasing proto samples, maintaining sample due dates, preparing priority lists for suppliers and logging samples as they arrive.
• Working closely with Design and Product Development to coordinate tech pack handovers, resolve development queries and prepare samples for seasonal buy meetings.
• Supporting Sustainability and wider Product teams with sustainable product development, while helping to maintain strong supplier relationships and ensure product is delivered to the required quality, margin and deadlines.
