About Clearmatics

Clearmatics is a B2B fintech startup that designs, develops and operates member-owned and member-governed digital cash settlement systems. Founded in 2015 as a London-based Ethereum R&D company, our mission is to reform market infrastructure by disrupting the common denominator across almost every market: cash settlement in fiat currency.

We are committed advocates of Open Source development and are active participants in the Web3 community. We have close ties to Ethereum Foundation and the Company is a founding member of the Ethereum Enterprise Alliance.

We are looking for people who are not afraid of unknowns and enjoy working with others to problem solve and break new ground. You should have more than a passing interest in the Ethereum or cryptocurrency space, with contributions to Open Source Projects being a distinct plus. You should be able to reason about technical problems, argue thoughtfully and contribute in a team setting. If you want rock star or ninja in your job title then this isn’t the right job for you.

We have a lot of hard problems to solve. If you’d like to make significant contributions to the blockchain ecosystem and think you are a match then we’d like to hear from you.
