  • Provide direct support to the C-suite, managing key tasks and projects from time to time.


Skills and Requirements:
  • 4 + years of office operations or similar experience in a high-paced, dynamic environment.

  • Strong project management with the ability to multitask, pivot, and reprioritize effectively.
  • A high level of self-awareness, strong customer service, and time management skills, with the ability to build strong connections.
  • Strong generalist skill set and ability to tackle new projects and challenges.
