• Assist GRC initiatives by mapping controls to internal policies and frameworks (e.g., SOC 2, NIST CSF, NYC DFS 500), identifying gaps, supporting audits and evidence collection, tracking remediation, and maintaining policies and control documentation.


• Work with engineering and business teams to champion security best practices, communicate risks to accountable owners, and assist with mitigation planning and execution.
