  • Maintain strict confidentiality and discretion in handling sensitive information.
  • Exhibit a high level of professionalism and service orientation in all communications and interactions.
  • Possess excellent written and verbal communication skills in English.
  • Be available on-demand (24/7 availability as needed, including across time zones).
  • Manage competing deadlines with strong organizational and multitasking abilities.

Travel Requirements

  • Primary operational hubs: Germany (Bremen), Turkey (Bodrum), Bulgaria (Sofia)
  • Frequent international travel required; ability to relocate or spend extended periods in key hubs.
  • Valid passport and readiness to travel on short notice for business or family support.

Additional Qualifications

  • Fluent English (spoken and written); additional languages an advantage.
  • Proven experience in managing executive operations, teams, or private offices at a top-tier level.

  • Able to pass comprehensive background checks (criminal, psychological, and substance screening).

Compensation & Contract

  • Competitive, performance-based compensation with relocation support if required.
  • Designed for ambitious professionals motivated by excellence, precision, and impact.
  • The role offers continuous growth, global exposure, and a front-row seat to the execution of complex, high-stakes projects.

In this role, “good” is not enough.
