Senior Executive Assistant

Position Overview

We are seeking a highly experienced, proactive Senior Executive Assistant to support our executive leadership team.

This role reports directly to the Inversion CTO. 

You thrive in fast-paced, ambiguous environments, anticipate needs before they arise, and bring structure to chaos. You are equally comfortable coordinating board meetings, managing sensitive information, and jumping in to solve operational problems on the fly.

• 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 
• Serve as a cultural ambassador—setting a high bar for professionalism and execution 

Qualifications

• 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 think like an operator, not just an assistant 
• You bring structure to ambiguity and calm to chaos 
• You anticipate needs before executives articulate them 
• You are trusted with the most sensitive information 
• You have a bias for action and thrive under pressure
