You'll help turn ambitious growth goals into structured, measurable campaigns that drive real commercial outcomes. You'll work closely with the VP Growth Marketing and cross-functional teams to test, learn, scale, and constantly raise the bar.

• Proficient in Excel/Sheets; comfortable managing performance reports and using reporting/analytics platforms.
