This is not a general marketing role. We’re looking for someone who genuinely enjoys media buying, performance data, creative testing and ecommerce growth.

How you’ll work

You’ll be hands-on in the ad accounts every day.

Our creative team produces a high volume of advertising, and you’ll be responsible for turning that creative into structured testing and actionable learning.

You’ll launch campaigns, monitor performance, identify winners, move budgets and help determine what should be tested next.

You’ll work closely with the Head of Meta, creative team and ecommerce team to understand what is driving performance across the entire customer journey.

3+ years of paid media experience

Strong hands-on Meta Ads experience

Triple Whale or similar attribution experience is beneficial

Strong analytical and numerical ability

Excellent attention to detail

The ability to move quickly and make commercially sound decisions

You’ll be joining an ambitious ecommerce team focused on building a world-class performance marketing operation.

You’ll have access to:

In-house video editors and graphic designers
