We are where the world checks out, enabling over 10 billion transactions daily for more than one billion global shoppers.

We move fast, think globally, and believe great teams are built by hiring exceptional people with conviction, curiosity, and the desire to make an impact. With 20 offices across six continents and London as our HQ, we’re shaping the future of fintech – and we’re just getting started. THE ROLE You will evolve Checkout.com http://Checkout.com's security posture across our multi-cloud environments and SIEM platform. This role sits at the intersection of cloud security engineering and detection capability — responsible for both hardening the infrastructure we operate on and ensuring we can see what's happening across it. You will lead security integration projects, guide cloud engineering teams, and drive continuous improvement across monitoring and detection, including applying AI to accelerate security operations.
