Amazon & Walmart Marketplace Manager

About the Role

We are looking for an experienced Amazon & Walmart Marketplace Manager / PPC Specialist to take ownership of the day-to-day management, advertising, optimisation, and growth of a CPG brand across Amazon and Walmart Marketplace.

The primary focus of this role will be PPC management, marketplace performance, listing optimisation, and overall channel growth. Amazon is already an established sales channel for the business, while Walmart Marketplace will need to be set up and launched from scratch. The successful candidate should be comfortable both optimising an existing marketplace operation and building a new marketplace channel from the ground up.

The ideal candidate should be capable of operating independently and effectively replacing much of the support traditionally provided by an external marketplace agency.
