The Engineering team is responsible for all aspects of software development for the firm, including platform engineering, quant engineering, and ML and AI infrastructure and implementation. As part of a nimble team in a growing organisation, you will be collaborating and developing real time solutions with your colleagues on a constant basis.

Our technical stack runs in a microservices architecture with Golang and Python services deployed on AWS alongside a Java/React user interface. We connect with our proprietary platform, MATRIX, to 15+ trading venues managing hundreds of millions of messages and orders per day. You will continue to scale and improve this platform as crypto gains further prominence at the heart of the world financial ecosystem.
