This Role Is Responsible For

• Building and executing security regression testing
• Driving threat modeling across existing and new functionality
• Conducting targeted offensive security activities (Red Team-style testing)
• Identifying real vulnerabilities based on a deep understanding of our platform and the OWASP Top 10 Web Application Security Risks
