  • Evaluate and recommend technologies and processes to mature the Insider Threat program.
  • Develop and refine response playbooks for various insider threat scenarios.
• Cross‑Functional Collaboration:
  • Serve as the primary technical liaison for the Insider Threat program.
  • Work with Legal, HR, and Privacy teams to ensure investigations respect employee privacy and legal guidelines.
  • Provide technical expertise during policy development and incident response planning.

• Deep understanding of security technologies such as SIEM, EDR, and UEBA data sources.
• Strong scripting and programming skills (Python, PowerShell) for automation and data analysis.
• Excellent written and verbal communication skills, able to explain technical concepts to non‑technical audiences.
• Experience working with legal and HR teams on sensitive employee‑related matters.

Preferred Qualifications

• Certifications such as GCIH, GCFA, GCTI, or similar.
• Experience with cloud‑based security and investigations (AWS, GCP, Azure).
