Executive Assistant to the C-suite

Istari Digital•Arlington, VA

About The Position

We're looking for an exceptional Executive Assistant to serve as the right hand to our executive leadership team (ELT). This isn't a traditional admin role — it's a high-trust, high-impact position at the center of a fast-moving organization operating across government, defense, and enterprise technology sectors. The person who thrives here is someone who knows how to manage complexity and confidentiality with ease, and takes genuine pride in making a high-performance executive more effective. You'll own ELT calendars, coordinate domestic and international travel, and serve as the operational backbone that keeps everything running — even when (especially when) everything is moving at once.

Requirements

7+ years of experience supporting a C-level or senior executive, with demonstrated longevity in those roles
Background in a high-tempo environment: defense, government, consulting, financial services, or enterprise technology preferred
Exceptional written and verbal communication skills
Strong command of productivity and calendar tools (Google Workspace, or equivalent)
Proven ability to handle sensitive information with complete discretion
Comfortable operating remotely and independently without close supervision
East Coast or Central U.S. time zone required
Experienced: You've supported a senior executive — ideally a C-level leader — for an extended period, following them through high-pressure environments and multiple roles or organizations
Discreet: You understand that the work you do is sometimes inherently confidential and you treat it that way, always
Proactive: You anticipate needs before they're expressed. You're two steps ahead.
Adaptable: You thrive in ambiguity and flux. No two weeks look the same, and that energizes rather than frustrates you
Relationship-forward: Stakeholders - both internal and external - enjoy working with you. You understand that being liked and trusted is how you get things done
Composed during travel : When the C-suite executives are on the road, you're in operational mode — monitoring, adjusting, and problem-solving in real time
