Staff Data Scientist - Performance Marketing

ABOUT QUINCE 

Founded in 2018, Quince was built to challenge the idea that nice things have to cost a lot. Our mission is simple: to make really high quality essentials for really low prices, produced fairly and sustainably. We believe everyone deserves exceptional craftsmanship and timeless design without the traditional markups. Quince is a direct-to-consumer (DTC) model that cuts out middlemen and leverages just-in-time manufacturing to minimize waste and maximize value.

Quince is a tech company disrupting the retail industry by putting AI, analytics and automation at the center of everything we do. Our unwavering commitment to excellence and company values guide our teams and actions:

• Customer First: We prioritize customer satisfaction in every decision.

• High Quality: True quality means premium materials and rigorous production standards you can feel good about.

• Essential Design: We focus on timeless, functional essentials instead of chasing trends.

• Always a Better Deal: Innovation and transparency ensure value for both customers and partners.

• Social & Environmental Responsibility: We commit to sustainable materials, ethical production, and fair wages.

Quince partners with world-class manufacturers across the globe and serves millions of customers. With strong investor backing and a focus on sustainable growth, we are a company that is rapidly scaling while maintaining a commitment to quality, simplicity, and radical price transparency.
