About the role

We are seeking a Senior Executive Assistant to join our high-performing, fast-paced team. This role is ideal for an experienced administrative professional (9+ years) who excels in complex support, thrives in dynamic environments, and brings a polished, confident presence to a team of seasoned leaders.

In this position, you’ll provide direct support to 3 Executives — COO, General Counsel, and CFO — ensuring seamless daily operations across demanding schedules, high-stakes meetings, and shifting priorities. The COO oversees a broad cross-functional scope across areas including Investor Relations, Marketing, Internal IT & Cybersecurity, and Office & Administration, making this a uniquely dynamic partnership role with visibility across the firm. You will operate as a trusted, steady partner to leadership—someone who anticipates needs, solves problems before they surface, and helps create the space for executives to stay focused on the highest-impact work.

• Draft and manage professional correspondence, deck materials, and meeting assets with clarity, accuracy, and polish.

• Track tasks, deadlines, and follow-ups across executives to drive operational alignment and maintain momentum.

• Help executives maintain focus by proactively managing context-switching, prioritization, and competing demands across multiple functions and stakeholders.

• Build strong working relationships across teams and functions, developing a deep understanding of the business and how the organization operates.

• Handle highly sensitive information with discretion, sound judgment, and the utmost integrity.

• Serve as a trusted partner—anticipating challenges, staying steps ahead, and proactively resolving issues.

• Collaborate with fellow Executive Assistants and step in when support is needed, contributing to a strong, cohesive admin team.

Qualifications

• 9+ years of relevant administrative experience, supporting senior leaders

• Proficiency in Google Workspace, Slack, AI tools (eg., Claude Co-work) Zoom and expense reporting tools

• Exceptionally organized with strong time-management, task-tracking, and follow-through.

• Clear, confident communicator—professional, diplomatic, and comfortable engaging with senior executives.

• Intellectually curious and proactive; eager to learn the business, build context, and ask thoughtful questions.

• Calm under pressure; able to navigate shifting demands with poise and focus.

• A collaborative team member who values partnership, reliability, and operational excellence.

• Committed to discretion, integrity, and professionalism in handling confidential information.

• Bachelor’s degree
