Smarkets Limited is looking for its first CISO / Senior Infosec Engineer to own security for a platform that has processed over £29 billion in volume. This is a rare 'builder' role where you’ll architect a cloud-native security program from scratch while leading the company’s expansion into US CFTC-regulated markets.
You’ll work with a high-performance stack of Rust and Kubernetes, enjoying a flat, self-managing culture and a direct line to the Board. If you’re a hands-on security leader who excels at bridging DevSecOps with rigorous financial regulatory standards, this is your opportunity to define the security DNA of a major fintech player.
Role overview
As the inaugural security hire at Smarkets Limited, you will build and own the information security program from the ground up. You’ll bridge engineering and compliance, securing real-time trading engines and cloud-native AWS environments while navigating CFTC regulatory mandates. This high-impact role reports directly to senior leadership and the Board.

Who this is a fit for
- Proven track record in security engineering, with hands-on experience securing Kubernetes workloads, AWS infrastructure, and building automated security pipelines within a high-growth, technically demanding environment.
- Extensive experience navigating financial regulations, specifically within CFTC, FCA, or similar frameworks, and the ability to translate complex regulatory requirements into practical, engineering-led security controls and policies.
- A builder mindset with the leadership maturity to act as a primary advisor to executive management while remaining deeply technical enough to own incident response and architectural design.
Why this role is remarkable
