Etsy

Etsy is a global marketplace for unique, handmade, and vintage goods that connects millions of creative sellers with buyers looking for distinctive products, processing billions of dollars in annual gross merchandise sales from its Brooklyn headquarters. The company's core technical challenges involve building search and discovery systems that can surface relevant items from a catalog of over 100 million listings where every product is essentially unique, developing recommendation engines that understand subjective aesthetic preferences, and maintaining a two-sided marketplace that balances buyer satisfaction with seller success. Engineers at Etsy work on search relevance and ranking, machine learning for personalization and fraud detection, and the platform infrastructure that supports a global marketplace with complex payment, shipping, and tax requirements. The company hires engineers who value craft in their own work and want to build technology that empowers independent creators and small businesses.
