Software Engineer, Growth

Quince•Palo Alto, CA

2h•$160,000 - $213,000•Hybrid

About The Position

We are looking for software engineers to build Quince’s next generation of growth marketing technology based in our Palo Alto, CA headquarters. We operate in a hybrid environment with 3 days in office. This team works at the intersection of engineering, data science, AI and marketing. We are building systems that power user acquisition and retention, use AI and data science models to guide budget and spend decisions, and optimize marketing performance using signals from inventory, demand forecasting, logistics, storefront behavior, customer intent, product similarity, and market intelligence. As Quince expands internationally, this AI-native platform will help drive smarter growth decisions across countries, categories, styles, and channels. The work may include backend services, APIs, customer-facing web and mobile applications, internal tools, personalization, experimentation, attribution, and data-driven workflows. We are looking for builders: curious, pragmatic, resourceful engineers who can turn ambiguous problems into simple, scalable systems. You do not need to come from a growth, marketing technology or advertising background. We care more about strong engineering fundamentals, ownership, product judgment, AI-forward thinking, and the ability to learn quickly.
