• Support efforts to ensure the systems security program remains compliant with required regulations
• Support and report on security-related audits to ensure actual practices comply with system security programs
• Perform system security administration tasks, including monitoring and correlating security events
• Collaborate with technical counterparts on implementation of security technologies and application security
• Maintain current knowledge of the latest cybersecurity threats, trends, and technologies
• Centrally monitor critical systems and respond to security events according to established procedures and experience
• Oversee incident response and risk assessments to support threat mitigation, coordinate with vendors, and facilitate security related incident response planning
• Investigate, document, and recommend corrective actions for information security incidents
• Respond to security incident alarms on a rotating, 24x7 schedule
• Perform other duties as assigned

Requirements:

• Knowledge of secure software development practices, secure software architecture principles, and common vulnerability classes with demonstrated ability to translate findings into practical engineering fixes
• Knowledge of cloud-native, containerized, and serverless security concepts; particularly AWS IAM and event-driven architectures
• Demonstrated understanding of secure application development, DevSecOps practices, and application security technologies (e.g., SAST, DAST, SCA, container security)
• Knowledge of AI/ML security concepts relevant to internal AI development (data governance, model/inference service security, and common AI threat scenarios). Equivalent demonstrated experience securing complex systems with the ability to quickly build AI security depth is acceptable
• Demonstrate experience with one or more of the following: Application Vulnerability Management, Identity and Access Management, and Data Loss Prevention process development, technical analysis and supporting technologies
• Demonstrate understanding in forensic investigations, data recovery and the handling of digital evidence
• Ability to develop, implement, and maintain new or maturing security systems, protocols, and processes within a complex organization
