• Define a pragmatic, risk-based security strategy across cloud infrastructure, applications, trading systems, and corporate environment
• Lead or support the investigation, containment and remediation of security incidents, including post-incident root cause analysis and corrective actions.
• Work with Engineering teams to build security into the SDLC — SAST, DAST, SCA, container/IaC scanning in CI/CD — without becoming a delivery bottleneck
• Implement controls across AWS, Kubernetes, containers, and IaC, hardening identity, secrets, and network access
• Establish security monitoring and detection across applications, APIs, and infrastructure
• Develop and maintain security policies, standards, and controls meeting DCM/DCO requirements
