• Executive-level communication with GC and owner counterparts.
• Building the SOPs that keep the office scalable as we grow.

Required Qualifications

• 3+ years supporting an executive team or running an office.
• Elite organization; nothing falls through the cracks.
• Discretion, judgment, and comfort with confidential information.
• Proficiency with Google Workspace, Microsoft Office, and modern collaboration tools.
