Senior Full Stack Engineer - Campaign Engine (all genders)

The Campaign Engine is a completely new product: its mission is to enable self-service campaign management for Retail Media Partners, giving them direct access to AY's unique loyalty frameworks: Missions & Coupons. This creates a compelling opportunity for partners to drive customer acquisition and incremental engagement within AY's existing customer base. Operating within an existing ecosystem, our evolution into specialized product teams provides an autonomous, greenfield-like environment.
