The ultimate aim is to optimize campaigns towards critical business goals such as Customer Acquisition Cost (CAC), Return on Ad Spend (ROAS), and payback periods, ensuring marketing investments are both effective and profitable.
• • Collaboration is central to this role. You will work closely with channel leads, creative teams, data analysts, and finance departments to validate and grow new sources of efficient demand. This cross-functional partnership is essential for ensuring campaigns are accurately tracked, measured, and reported, and that insights are translated into strategic decisions.
