As Lead Executive Assistant & Private Office Operations Manager (CEO Office) of Constructor Group, you will operate at the centre of a dynamic, global ecosystem spanning Germany, Turkey, and Bulgaria. This position is designed for an experienced professional with 15+ years of proven excellence in executive operations, project leadership, or private office management — someone who combines operational precision, strategic judgment, and the stamina to lead in a constantly changing, high-performance environment.
This is a senior, hands-on leadership role combining Executive Assistant & Personal Assistant, Private Office, and team management responsibilities.
You will manage and develop a team of Executive Assistants and 10–15 supporting personas (drivers, chefs, housekeepers, coordinators, etc.), ensuring flawless coordination across all aspects of the CEO’s professional and personal ecosystem. Your ultimate mission is simple but demanding: to maximise the CEO’s productivity, anticipate needs before they arise, and make the impossible happen smoothly and discreetly.
This is a highly hands-on leadership role. While you will manage and develop the administrative support team, you will also personally execute critical Executive Assistant and Personal Assistant tasks for the CEO when needed. The successful candidate must be comfortable switching between strategic coordination, team leadership, and direct, hands-on support — including calendar management, travel coordination, personal errands, vendor communication, last-minute problem solving, and confidential personal matters.
