• Internal Team Leadership — Communicate expectations to internal staff and vendors; build scalable processes and operational workflows to manage complex responsibilities and ensure peak team performance.
• Event & Convening Support — Work alongside the Director of Strategic Engagement to plan and run exclusive gatherings; coordinate invitations, guest logistics and post-event follow-up with an emphasis on operational excellence and guest experience.
• Relationship Stewardship — Craft thoughtful, high-quality correspondence and manage relationships with the Founder’s network of leaders, influencers, and long-standing contacts; ensure contacts feel engaged and valued.
• Confidentiality & Professionalism — Maintain the highest standards of discretion, professionalism and judgement in all internal and external interactions.
