• Compliance & Policy Governance: Partner closely with Governance, Risk, and Compliance (GRC) teams to author infrastructure security policies and ensure adherence to industry standards and regulatory frameworks.
• Cross-Functional Collaboration: Partner with InfoSec peers (AppSec, Detection & Response, CloudSec, NetSec) and core Infrastructure engineering teams to drive secure engineering outcomes.
• Pragmatic Build vs. Buy Strategy: Evaluate third-party vendor security tools against in-house software solutions to resolve infrastructure security requirements efficiently.
