Exeuctive Assistant + Office Manager (Series A)

New York, US Full-time

This is a hybrid Executive Assistant + Office Manager + Culture Operator role at a Series A company.

This is an in-office, high-trust, high-responsibility role for someone who thrives in a fast-paced environment and enjoys wearing multiple hats.

We’re looking for an exceptionally organized, high-ownership operator who is proactive, detail-obsessed, and thrives in a fast-paced, in-office startup environment where no task is too small. The ideal candidate is highly trustworthy, polished, and execution-focused, with strong calendar, logistics, and administrative skills and the ability to seamlessly support both founder priorities and daily office operations.

  • Create detailed itineraries for founder and team travel
  • Handle last-minute changes and travel issues seamlessly
  • Coordinate offsites, conferences, and partner visits

Office Management

  • Ensure the office is clean, organized, and fully operational
  • Light daily office upkeep (including bathrooms, kitchen, and common areas)
  • Manage office supplies, snacks, and equipment
  • Coordinate vendors, deliveries, and office maintenance
  • Maintain a high-functioning, professional workspace environment
