Summary of Position

Penta Group is seeking an exceptional Executive Assistant to serve as a strategic partner and force multiplier for our CEO. This is not a traditional administrative role. We’re looking for someone who can operate at the speed and altitude of a high-performing executive, anticipate needs before they’re voiced, and manage the CEO’s time, information, and priorities with total discretion and precision.

The right candidate will be a highly polished, sharp, and resourceful professional with a track record of supporting C-suite executives in fast-paced, high-stakes environments. You will be a gatekeeper, a sounding board, a fixer, and a trusted extension of the CEO — equally comfortable managing a complex international travel itinerary, synthesizing a board deck, or navigating a sensitive stakeholder conversation. This role demands exceptional judgment, unflappable composure under pressure, and the ability to represent the CEO’s interests and voice with credibility across the firm and with external partners, clients, and board members.

We’re especially interested in candidates who are fluent with AI tools and know how to use them to work faster and smarter, whether that’s drafting and refining communications, synthesizing research and briefing materials, or streamlining scheduling and administrative workflows. This is a role for someone who sees AI as a lever for higher-value work, not a replacement for judgment.

The CEO is supported by a Chief of Staff for strategic initiatives and cross-functional priorities. This role is focused on calendar management, logistics, and operational execution for the CEO, along with scheduling support for other members of the C-suite as needed.
