Ethical Walls & Data Isolation: Implement and audit security barriers within Document Management Systems (DMS) to prevent internal conflicts of interest and unauthorized file access.

Legal Tech Integration (Preferred): Familiarity securing legal technologies such as Document Management Systems (iManage, NetDocuments) or eDiscovery tools (Relativity).
Autonomy & Impact: Proven ability to work independently, manage multiple security tools simultaneously, and pivot quickly between daily operations and project engineering.
Soft Skills: Exceptional discretion regarding confidential data and the ability to explain technical risks simply to attorneys, partners, and clients.
