Omni Activation Manager, Walmart – Mars Petcare

Location: USA-Arkansas-Bentonville

Bentonville, AR

This role is based in Bentonville, AR with regular in-office collaboration expected. Flexibility is a key enabler, empowering associates to make choices that support both business outcomes and personal needs, including occasional remote work.

The Omni Activation Manager is a critical growth driver for the Mars Pet Nutrition business at Walmart. Based in Bentonville, Arkansas, this role develops and executes integrated omnichannel activation strategies that drive brand growth, shopper engagement, digital penetration, and incremental sales across the Cat and Treats portfolio.

The Omni Activation Manager works closely with sales, brand marketing, agency partners, Walmart Connect, and Walmart merchants to build holistic activation plans that connect digital and physical shopper experiences. The Manager will lead a diverse portfolio of activation levers including retail media, paid search, display advertising, Walmart Cash, shopper marketing programs, in-store displays, and marketing events to ensure every activation is aligned against a common objective: driving sustainable sales growth for Mars at Walmart.

As the team's subject matter expert for retail media and always-on optimization, this individual will serve as the primary day-to-day point of contact with Walmart Connect and agency partners, leading performance optimization, test-and-learn initiatives, and continuous improvement efforts. Success in this role requires equal parts analytical capability and commercial curiosity. The ideal candidate understands that metrics rarely tell the whole story and is motivated to continuously uncover the underlying drivers of shopper behavior, campaign performance, and sales outcomes.

Rather than simply reporting what happened, this individual is expected to understand why it happened and how future activations can be improved.
