Job Description

Digital Commerce (DCom) is set to represent 35%+ of all CPG sales in the not-too-distant future. Mars Wrigley has an ambition to more than triple its DCom sales over the coming years and accelerating Omnichannel (“bricks & clicks”), enabled by Retail Media, is one of the largest growth opportunities in front of us. To enable this ambition, Mars Wrigley has created a Global Center of Acceleration (CoA), that works together with markets, regions, and cross-functional partners to develop strategies and plans to fuel faster growth.

Retail Media is when a retailer uses its own digital properties to sell ads to brands with targeting informed by their customers’ purchase data. In 2023, it is estimated that $52B will be spent on Retail Media networks, with the potential to double over the next 3 years as more retailers race to catch up with Amazon’s successful Ads business. Understanding which networks to prioritize, what inventory to buy, and how much to invest is key to driving competitive & quality growth for Mars Wrigley.

As the Global Retail Media Strategy Director, you’ll be the go-to-expert on all things Retail Media to help Mars Wrigley maximize the Retail Media opportunity across 200+ Omnichannel key accounts in 25+ markets. Some of your key responsibilities will include developing a where-to-play and how-to-win strategy for Retail Media platforms, building an end-to-end toolkit for local market teams covering key topics like budgeting & planning best practice, supporting local teams on Retail Media JBP negotiations, and leading a global community of practice for Mars “One Demand” performance squads and Omnichannel account teams. You will report into the Head of Digital Shelf & Retail Media, and partner with other key Associates across DCom Customer and Media/Performance Marketing.
