You’ll mentor the Offensive Security Engineer and serve as a technical authority across product and platform teams.

Individual Contributor Focus

• Communicates risk and remediation trade-offs to cross-functional stakeholders at the project and product-line level, influencing engineering roadmaps where security debt is material.
