What you’ll do

Executive Leverage & Time Allocation

• Maximize CEO leverage: Own time, priorities, and follow-through across the CEO’s agenda. Own the CEO’s calendar as a capital allocation problem—design weeks for highest ROI; create focus blocks; pre-read gates; hard trade-offs.
• Meeting management: Prep, brief, and debrief the CEO for key meetings; drive pre-work, set decision frames, capture actions, ensure follow-through.
• Comms management: Manage communications triage (email/Slack/Text) with clear SLAs and judgment about what must reach the CEO.
• Operate with urgency: Be highly reliable and available, including after hours, and during travel time zones or other critical periods.
• Exercise impeccable judgment: Handle highly sensitive information with absolute discretion.
• Bias to action: Roll up sleeves—no task too big or small; own outcomes end-to-end.
• Own the calendar: Manage a dynamic, high-volume schedule; screen requests, set priorities, and resolve conflicts proactively.
• Run meetings & travel: Coordinate domestic/international meetings and end-to-end travel (time zones, visas, itineraries, briefing packs, comms).
• Handle complex admin: Deliver diverse, confidential work with tact, initiative, and anticipation.
• Deliver at pace: Ship a high volume of work with minimal guidance; respond rapidly to time-critical issues.

Executive Operating System

• Drive operational excellence: Partner with senior leadership to design and run the executive operating cadence that increases throughput.
• Build and run the cadence for staff meetings, weekly exec reviews, quarterly OKR checkpoints, and off-sites.
• Maintain decision logs, action trackers, and “single source of truth” in a well-managed up to date collaboration doc system.
• Implement automations and AI agents (e.g., GPT + Zapier) for recurring workflows (agenda packs, trip briefs, follow-ups).
