Senior Manager, Amazon (Marketplaces)

About the Role

As Senior Manager, Amazon & Marketplaces, you will run the day-to-day execution of Comfrt's marketplace portfolio. Amazon is our anchor platform, and you will support the build-out of the next wave of marketplaces, starting with Faire and extending to US and international platforms. You will turn portfolio strategy from our Senior Director into clear plans, owners, and measurable results across GMV, margin, and brand health.

You bring hands-on experience in a fast-moving, multi-SKU business, ideally in retail or beauty, where catalog complexity, inventory decisions, and promotional calendars change quickly. Amazon experience is a strong plus. You are comfortable managing the detail, owning the numbers, and turning data into action.

You will partner with Paid Media, Marketing, Ops, Merchandising, Finance, CX, Data & Insights, and Performance-Led Creative to grow marketplaces efficiently, strengthen Comfrt's brand on each platform, and create halo effect into DTC and other channels.
