Senior Frontend Engineer


OpenSea is the first and largest marketplace for user-owned digital goods, which include collectibles, gaming items, domain names, digital art, and other items backed by a blockchain. These digital goods have brand new properties: they’re unique, provably scarce, liquid, and usable across multiple applications. We're building a brand new economy from the ground up based on digital ownership. The team has backgrounds from Stanford, UC Berkeley, Palantir, Google, Facebook, and Pinterest, funded by YCombinator, Founders Fund, Coinbase Ventures, 1Confirmation, Blockstack, and Blockchain Capital.

When hiring candidates, we look for signals that a candidate will thrive in our culture, where we default to trust, embrace feedback, grow rapidly, and love our work.

We're looking for an experienced, detail-oriented software engineer with an enthusiasm for building and scaling feature-rich, well-tested, and polished applications. This individual will spearhead core features of the OpenSea marketplace platform, as well as our developer integrations.
