Our platform helps the most ambitious businesses deliver effortless digital experiences, at scale. \nIf 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. \nWith 20 offices across six continents and London as our HQ, we’re shaping the future of fintech - and we’re just getting started.\nThe role\nYou will be a hands-on operator at the heart of the Cyber Security team, helping to run, harden, and continuously improve the day-to-day machinery of security. Where the Detection & Threat Engineer defines what \"good\" looks like, you help make it real, turning standards, runbooks, and tooling into reliable, repeatable operational practice.\nThis is a delivery-focused role for an experienced practitioner. You will spend your time in the tooling, in the tickets, and in the detail: enhancing the platforms the team depends on, tightening procedures, and making sure findings, alerts, and remediation work actually get closed out rather than left to drift.\nYou will partner closely with Senior Detection & Threat Engineers, Application Security, Information Security, Security Operations, and Engineering executing against the standards they set, feeding operational insight back up, and progressively taking ownership of the tooling and procedures that keep security operations running.\nWhat you'll be responsible for\nSupporting and enhancing security tooling SIEM, EDR, DLP, vulnerability management, and automation platforms including configuration, tuning, and day-to-day maintenance\n\nBuilding and improving operational procedures, runbooks, and playbooks so the team's response is consistent and repeatable\n\nTriaging and handling security alerts, escalating high-severity events, and contributing to incident response under the direction of senior engineers\n\nTracking, coordinating, and driving pentest and vulnerability findings through to remediation across engineering teams (ownership, action plans, status, closure)\n\nMaintaining the accuracy and hygiene of security data asset inventories, finding trackers, and remediation records\n\nSupporting detection deployment and validation, and feeding operational feedback into detection tuning to reduce noise and alert fatigue\n\nAssisting with scripting and automation to remove manual toil from recurring operational tasks\n\nProducing clear operational reporting and metrics on findings, remediation progress, and tooling health\n\nWhat we're looking for\n5+ years of hands-on experience in a Security Operations, SOC, or equivalent operational security role\n\nPractical experience operating modern security tooling SIEM (e.g. Sentinel), Data Loss Prevention (DLP) tools, EDR, and vulnerability management platforms\n\nSolid understanding of security operations workflows: alert triage, incident handling, and vulnerability/finding remediation lifecycles\n\nComfort with scripting to support automation and tooling (e.g. Python, KQL)\n\nExperience coordinating remediation across multiple engineering or platform teams, and keeping work moving to closure\n\nWorking knowledge of cloud environments (e.g. AWS, Azure and GCP) and how security operations apply across cloud and SaaS\n\nFamiliarity with common frameworks and standards such as PCI DSS, NIST CSF, SOC 2, ISO 27001, CIS Benchmarks, and MITRE ATT&CK\n\nA pragmatic, ownership-minded operator: methodical, detail-oriented, and focused on getting things fixed rather than just logged\n\nAdditional Information\nBring all of you to work\nWe create the conditions for high performers to thrive, through real ownership, fewer blockers, and work that makes a difference from day one.\nHere, you’ll move fast, take on meaningful challenges, and be recognized for the impact you deliver. It’s a place where ambition gets met with opportunity, and where your growth is in your hands.\nWe work as one team, and we back each other to succeed. So whatever your background or identity, if you’re ready to grow and make a difference, you’ll be right at home here.\nIt’s important we set you up for success and make our process as accessible as possible. So let us know in your application, or tell your recruiter directly, if you need anything to make your experience or working environment more comfortable.\nLife atCheckout.com\nWe understand that work is just one part of your life.
