About Clearmatics

Clearmatics is a protocol engineering company. We are building a new financial market architecture that is more open, fair, and resilient than the legacy systems that are in use today. We develop protocols and software that create new markets for risk and more efficient infrastructure for trading, backed by a robust and scalable blockchain network, and secured with modern cryptographic techniques and economic mechanism design.

Clearmatics is based in London but operates on a ‘remote first’ model. We welcome candidates from all over the world. We have close ties to the Open Source and Ethereum communities, with Vitalik Buterin as an adviser.

The Research group at Clearmatics is dedicated to developing solutions to the hard problems needed to advance our mission. We are academics and protocol engineers collaborating with teams inside and outside the company to translate theoretical results into running software implementations. Our work spans cryptography, game-theory, (computer) networking, identity systems and secure software implementation research, with a focus on their domain applications in financial markets.

We’re looking to hire a Protocol Engineer to expand our Research team.
