Site Reliability Engineer

Web3 and the crypto ecosystem more broadly has historically had a chain centric worldview. We believe this is an outdated framework originating from a perceived scarcity in blockspace due to bundling of credible commitment machines with global consensus.

We believe an ecosystem wide transition towards an account centric worldview will enable the consolidation of an increasingly fragmented user experience.

At OneBalance we are developing a non-custodial account model to provide users with a seamless, account-centric experience. Our model introduces resource locks to accounts on credible commitment machines. OneBalance is a framework for managing these Credible Accounts. Our goal is to provide a missing component of the web3 stack that will help onboard the first billion humans onto crypto. You can learn more about the OneBalance vision here.

The Role
