Administrateur exécutif expérimenté (H/F)

Job Description

RETI Center is seeking an experienced, highly organized Executive Administrator to serve as a high-trust administrative and coordination partner to the Executive Director and Executive Leadership Team. This is far more than a task-based administrative role - it is an opportunity to help create steadiness, rhythm, and follow-through in support of visionary leadership, while contributing to one of New York City's most innovative climate solutions organizations.

The Executive Administrator will create systems, manage priorities, organize information, drive projects forward, and ensure the Executive Leadership Team can focus on vision, maximum impact, partnerships, fundraising, and organizational growth.

This position is ideal for someone who loves creating order from complexity, anticipates needs before they arise, enjoys solving problems independently, and thrives in a fast-paced, mission-driven environment where every day is different.

If you enjoy building systems, learning continuously, and helping visionary leaders bring their work into the world with more clarity and momentum, we'd love to meet you.

The ideal candidate is proactive, exceptionally organized, technologically savvy, highly trustworthy, and capable of managing multiple priorities with professionalism and sound judgment.

This role combines executive support, operations, communications, research, documentation, and project management into one highly impactful position.
