Senior Linux Systems Administrator
Cooler Screens was founded on the core idea that consumers deserve a far better background than what is available today in bricks-and-mortar retail. We call this concept “CX” and it guides all that we do. We have begun the CX journey by bringing what consumers love about shopping online to the frozen and refrigerated food aisle. Cooler Screens is re-imagining the business of brick-and-mortar retail for retailers and brands. We are transforming retail cooler surfaces into IoT enabled screens that deliver new marketing opportunities and smart merchandising for the ultimate shopper background.
