About the Job

This is an opportunity to become a trusted working partner to a fast-moving founder and CEO, building and operating the core systems that keep his professional and personal worlds running smoothly as priorities change. This is a hands-on role that offers an unusually close view into building an ambitious hard-tech company and considerable latitude to improve how the CEO operates.

Working closely with the Chief of Staff to the CEO, you will have broad ownership over the CEO’s day-to-day and meaningful freedom to make it work better. You will execute across inbox management, calendaring, travel, coordination, events, external engagements, and personal logistics. The work requires sound judgment at every level and a no-task-too-small mindset.

You may be a career EA, or you may have built the same muscles in another demanding environment. You hold an exacting standard for your work, notice details others miss, and follow through reliably. You combine low ego and high energy with warmth, good humor, and polish. You communicate exceptionally well, handle sensitive information with absolute discretion, and are energized by the pace and variety of the role.

The CEO’s work does not always fit within fixed processes, and the day will not always unfold as planned. Success requires someone who can build useful systems without becoming overly attached to them, and who can persist, redirect, and adapt without creating friction. In return, the role offers remarkable scope, ownership, and proximity to consequential work, along with the opportunity to become indispensable to a founder building something exceptional.

Responsibilities

• Inbox & Communications: Keep the CEO’s inbox and inbound communications moving with exceptional responsiveness. Identify and raise urgent items, draft crisp, clear, tactful communications, and develop responses as appropriate.
• Calendar & Scheduling: Own the CEO’s calendar and scheduling including prioritization, protecting focus time, and optimizing for efficiency and daily flow. Coordinate with internal and external stakeholders cleanly and without creating friction. Support scheduling for other company leaders at the CEO’s discretion.
• Event & Visit Coordination: Own planning, coordination, and execution for site visits and external engagements including investor visits, group tours, speaking opportunities, and media appearances.
• Travel: Arrange CEO travel including last-minute bookings, transportation, required documentation, and occasional on-the-ground support. Support travel arrangements for other company leaders at the CEO’s discretion.
• Meeting Preparation & Follow-Through: Ensure the CEO is on time and prepared for meetings and commitments. Manage reminders and capture important decisions, follow-ups, next steps, and other key details.
• Confidentiality & Judgment: Handle sensitive personal and professional information with absolute discretion. Read situations well, including when to engage, when to be brief, and when not to interrupt.
• Personal Assistance & Life Infrastructure: Anticipate and address practical needs that make the CEO’s life easier and reduce recurring sources of friction. Build and maintain low-touch, reliable systems for facilitating household management, appointments, errands, and other personal logistics.
