ABOUT SMARKETS

Smarkets is a prediction market exchange for sports and political trading, having handled over $50 billion in volume since 2010. We're upending sports betting with the fairest prices, the best technology, and a superior customer experience — powered by attracting great people and building a high-performance environment where they thrive. We're looking for an atypical candidate with strong regulated-business experience to support our growing CFTC business.

THE ROLE

This is our inaugural security hire, working alongside Infrastructure to protect the distributed, real-time systems behind our trading engine. You'll lead our information security programme across our core products and our DCM/DCO entities — a founding build, standing up security engineering from the ground up through go-live and maturing it as we scale. Reporting directly to senior leadership and the Board, you'll own security posture updates and ensure our risk management and incident response frameworks exceed regulatory and operational standards.
