ABOUT QUINCE

Quince is a destination for builders, creators, innovators, and operators who want to come together and challenge the status quo. Our mission is simple: make really high quality essentials for really low prices, fairly and sustainably. We deliver on that mission through a unique manufacturer-to-consumer (M2C) model eliminating the layers of traditional retail that add cost and result in consumers paying more than they need to. We find, build relationships with, and work directly with the manufacturing partners behind some of the world’s finest products. From there, our teams design smart, efficient operational processes and build and deploy proprietary technology, AI, and analytics to help us scale fast.

What began with a small assortment of elevated basics has quickly grown into a cross-category brand spanning apparel, accessories, home goods, and more. Today, tens of millions of people across a growing number of countries come – and return – to Quince because they trust us to deliver.

OUR CULTURE

Quince is a culture built for builders by builders. Our way of working starts with a blank sheet of paper. We question conventional thinking, use technology and data to uncover new opportunities, and move quickly to turn ideas into reality. We aren’t interested in replicating how others do retail. We’re building a better way – at a speed and scale unlike anything that’s been done before.

We dream big and chase the hard problems others shy away from. Rejecting long-held assumptions is part of our company's DNA. Where conventional wisdom says you have to choose – soft or durable, speed or rigor, quality or price – we ask why that trade-off has to exist in the first place.
Our pace is fast and the bar is high because our customers expect a lot from us and we refuse to let them down. We believe the best results come from challenging ourselves, learning from one another, and building on each other's strengths.
Here, responsibility is not determined by role, tenure, or seniority. Every team member - no matter their level - has the opportunity to drive our business and shape our trajectory.

If you’re someone who likes to imagine new possibilities and build better systems rather than plug-in to outdated ones, Quince is the place for you.

Design and scale custom automated content loops and multi-modal asset pipelines that autonomously synthesize high-quality marketing copy, graphics, and video layouts.
Build and refine autonomous decisioning pipelines that integrate with data matrices to dynamically model and optimize real-time asset deployment across platform networks.
Establish rigorous confidence limits, prompt versioning protocols, and automated fallback/rollback frameworks to handle complex LLM failure modes safely under heavy web scale.
Partner closely with Product Management, Data Science, and Engineering squads to define unified catalog schemas and eliminate cross-platform ingestion and data latency bottlenecks.
Improve ads delivery efficiency by 20% in the first 6 months, while scaling volume.

Qualifications

Experience building custom developer velocity extensions or generative asset platforms within direct-to-consumer (DTC), retail, or e-commerce environments.
Deep familiarity with advertising networks, performance marketing data structures, programmatic bidding models, or real-time event-driven architectures.
An advanced degree (Masters or PhD) in computer science, mathematics, statistics, physics or a highly quantitative field.
