Ecommerce Product Manager

Thirdlove
San Francisco, CA

Who We Are

Thirdlove disrupted the lingerie industry by empowering women to find their perfect fit online with our innovative Fitting Room® quiz and is one of the original brands to operate 100% direct-to-consumer. All design and R&D is done in-house, and our extensive and complex supply chain is fully managed by our team. Inclusivity is at the core of who we are and how we serve our customers and build our teams.

Traditionally, women were given a choice between two options when it came to their bras and underwear: Be sexy, or be comfortable. Our Cofounders: Heidi Zak, and Ra’el Cohen, thought that was outdated too — so, in 2013, they created Thirdlove — a third, better option, which doesn’t force us to choose between being sexy or comfortable.

What Our Team Embodies

Our culture is collaborative, fast-paced, and data-driven, and we were most recently recognized with the Great Place to Work certification for the 5th year in a row. This recognition is given to a very small percentage of companies who apply for it and determined by employees’ real-time reports of their company culture. Earning this designation demonstrates to us that our team at Thirdlove is inspired by our mission, engaged in their everyday work, and enjoy partnering with our teammates and customers. If you want to impact millions of people, find your fit, and propel your career forward, we’d love to hear from you.
