Manage highly confidential and sensitive information with discretion and professionalism

Anticipate executive needs, identify potential challenges, and proactively implement solutions

Support strategic initiatives, special projects, and broader administrative priorities as required

What We’re Looking For

5+ years of Executive Assistant experience supporting senior executives or executive leadership teams

Proven ability to manage multiple priorities within a fast‑paced corporate environment

Advanced proficiency with Microsoft Office, including Outlook, PowerPoint, Word, and Excel

Strong experience preparing executive presentations, reports, and business materials

Highly proactive, resourceful, and solutions‑oriented approach

Ability to work independently and confidently with minimal oversight

This opportunity is ideal for an Executive Assistant who thrives as a true business partner to senior leadership, anticipates needs before they arise, takes ownership with minimal direction, and enjoys operating at a highly strategic level within a fast‑paced executive environment.

All applications are reviewed by our recruitment team, and hiring decisions are made by people. We may also use AI-enabled tools to support parts of the application review process.
