• Bonus: Okta or equivalent at depth. SIEM and SOAR engineering. macOS and Windows fleet security. Insider-risk programs.

• Secure the corporate environment end to end: identity, endpoints, SaaS, and email for a workforce growing 10x.
• Build detection and response for the corp attack surface, from phishing to token theft to insider risk.
• Engineer zero-trust access: SSO, device trust, and least-privilege provisioning that scale with hiring instead of against it.
• Automate the controls so security runs as code and policy, not tickets and exceptions.
