• 8+ years of experience as an Executive Assistant, including 3+ years supporting a CEO/founder or top C-suite at a high-bar organization (startup, hedge fund, big tech, or top-tier firm).


• Evidence of operational judgment under pressure: you’ve navigated mission-critical situations (e.g., last-minute travel changes, board pivots, multi-party offsites) without drama.


• Exceptional writing skills (concise, executive-ready) and a meticulous attention to detail (zero typos, zero misses).


• Strong organizational skills with a talent for process improvement and efficiency; comfort with automation tools is a plus.


• Technically proficient in managing complex compliance processes through advanced utilization of platforms like Google Workspace and Slack.


• Based in New York City, with the ability to work onsite regularly to support the executive team in our midtown office.
