Executive Assistant + Office Manager + Culture Operator
This is a hybrid role at a Series A company. You will own the day-to-day logistics of the founder's schedule, office operations, and internal team experience ensuring the company runs smoothly and the founder can stay focused on high-impact work.
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
Team & Culture Operations ("Vibe Creator")
- Organize team events, celebrations, and offsites
- Help foster a positive, energetic, and high-performance office culture
- Support onboarding logistics for new hires
- Create a welcoming and polished in-office experience
- Be a go-to resource for day-to-day team needs
