Growth Marketing Manager: Paid Search and Display

Who We Are For too long, the bra industry was stuck in outdated ideas, forcing women to choose between feeling sexy or comfortable. So in 2013, Heidi Zak and Ra’el Cohen created Thirdlove–a third, better option designed to help women look and feel their best. Prioritizing real-world fit over outdated standards, Thirdlove disrupted the industry by inventing half-cup sizes and the Fitting Room® quiz. The result was a more precise fit that offered comfort without sacrificing style. Today, Thirdlove remains an innovative design-led brand, handling everything from R&D to the supply chain in-house to get every detail just right. How We Work Our culture is inclusive, collaborative, fast-paced, and data-driven. We’ve been certified as a Great Place to Work® for four consecutive years, based on feedback from our own team. If you want to make an impact while propelling your career forward, we’d love to hear from you. What We Are Looking For Paid Search, display, and video are central to how we acquire customers across the full funnel.
