Job description

Overview

Clearmatics is a blockchain protocol engineering company that builds decentralised financial market infrastructures that are more open, efficient, and resilient than those serving legacy market structures of today.

We have a bold vision for this new market infrastructure - enabling market participants to solve currently unaddressed problems of the real economy, including "missing markets" problems. We aim to achieve our vision through technologies that allow peer-to-peer trading and settlement within new markets, and with digital assets whose values track real-world risk factors that currently have no suitable expression in legacy markets.

No matter the nature of a risk factor, whether macro-economic or relating to real-world metrics such as climate data, our mission is to make important risk factors tradable; by anyone, anywhere, without reliance on financial intermediaries. We are building this new infrastructure in collaboration with incredible trading and blockchain communities.

Clearmatics was founded in 2015, and we have ever since been committed advocates of Open Source development, and active participants in the blockchain and cryptography research communities. We\'ve also been an active participant and supporter of decentralized infrastructure initiatives.

We\'re growing our team and are looking for a Blockchain QA Engineer to join us and become part of our journey.

Our stack is Ethereum-like, so familiarity with - and passion for - the space is key.

Some of the areas we tackle include blockchain infrastructure optimised for financial use-cases, protocols for specific applications (such as smart contract-based derivatives, synthetic assets and cryptocurrency stabilization), scalability and privacy.

Currently the Clearmatics team is heavily involved as the Launch Partner for the Autonity Project. Autonity is an EVM based public blockchain for decentralised derivatives clearing. You can learn more about the Autonity project and their Forecastathon trading competition below:
