• Execute and lead penetration tests in complex corporate environments.
• Participate in Red Team exercises, applying evasion techniques against EDR, XDR, WAF and antivirus solutions.
• Identify vulnerabilities, analyze their impact and propose effective mitigation strategies.
• Develop or adapt offensive tools and automations using Python, Bash or PowerShell.
• Produce clear technical and executive reports focused on risk.
• Present findings to both technical and business audiences.
• Manage technical audit projects, coordinating scope, timelines and deliverables.
