Full Job Description
Company Description We’re http://checkout.comCheckout.com http://Checkout.com. You might not know our name, but companies like eBay, Spotify, Klarna, Uber, and Sony do, because we’re behind many of the digital experiences you use every day. We are where the world checks out, enabling over 10 billion transactions daily for more than one billion global shoppers. Whether you want to book a holiday, order food, renew a subscription, or check out online, there’s a good chance our tech powers the payments behind the scenes. Our platform helps the most ambitious businesses deliver effortless digital experiences, at scale. If you want to do career-defining work, you’ve come to the right place. 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. This is not a tool-monitoring role. You are here to architect secure cloud environments, build and enhance detection logic at scale, and drive measurable improvements to our security baseline across AWS, Azure, and GCP. You will partner closely with Engineering, GRC, Technology Risk and Security Operations - defining standards, fine tuning the SIEM, and progressively taking on the most complex cloud security and detection engineering challenges across the organisation.
