• Collaborate with development teams to ensure security best practices are integrated into CI/CD pipelines
• Secure and enhance CI/CD pipelines; integrate and maintain code scanning platforms
• Monitor and respond to security events and incidents in cloud and hybrid environments
• Maintain SIEM data pipelines needed for reliable alerting
• Build, deploy, and maintain security operations infrastructure using Python, Terraform, and configuration management (e.g., Puppet)
