Coordinate board meetings, investor updates, and executive offsites

Handle confidential and sensitive information with discretion

Company & Team Support

Plan and execute internal events, leadership offsites, and team meetings
Assist with onboarding senior hires and executive-level recruiting coordination

Qualifications

5+ years of experience supporting C-level executives (preferably in a startup or high-growth environment)
Experience in aerospace, defense, hardware, or deep tech environments
Proven ability to manage competing priorities with speed and accuracy
Exceptional organizational skills and attention to detail
Strong written and verbal communication skills
High level of discretion
Ability to operate independently and take full ownership of responsibilities
Must have the ability to obtain and maintain a U.S. government Secret/Top Secret security clearance

What Sets You Apart

You are trusted with the most sensitive information
You have a bias for action and thrive under pressure
