OpenSea is the first and largest marketplace for non-fungible tokens, or NFTs. Applications for NFTs include collectibles, gaming items, domain names, digital art, and many other items backed by a blockchain. NFTs have brand new properties that go beyond traditional digital items: they’re unique, provably scarce, liquid, and usable across multiple applications. At OpenSea, we're excited about building a brand new economy from the ground up based on true digital ownership and are proud to be recognized as  Y Combinator's #26ranked top private company.

We are dedicated to equal employment opportunities regardless of race, color, ancestry, religion, sex, national origin, sexual orientation, age, citizenship, marital status, disability, gender identity or Veteran status. To help facilitate this, we support remote, hybrid or onsite work at either New York City or San Francisco for the majority of our opportunities.
