Everybody and their mother working on blockchains loves the word “decentralization”. On a broad, world-changing scale, we can all agree that it’s important. Yet, when we zoom into the specifics of how to build this decentralized world, we find many diverse approaches. Whether it’s defi, identity, art, healthcare, or anything in between, a single dependency unites each dream for the future: scalability. We at OP Labs are building the critical infrastructure to address this need -- a protocol called Optimism -- an extension to Ethereum that scales both its technology and philosophy and enables orders of magnitude more performance. Ethereum will enable the greatest change in human coordination since the birth of the internet, and through the Optimism protocol, OP Labs is here to help bring it to the masses. Join a team that is passionate about solving complex problems by exploring (and/or expanding) the boundaries of technology! We are a remote first company with local hubs where teams can co-work IRL, when safely able to do so. We aim to grow quickly, so come help us build! :-)
