Office Manager & EA to the CEO

Manifest OS•New York, NY

10d•$66,000 - $80,000•Onsite

About The Position

This role is the operational backbone of our Flatiron office and the person who keeps our CEO's day running without friction. You'll manage a busy calendar, coordinate logistics, and own the look, feel, and rhythm of our space as we grow. It's a high-trust, high-visibility role for someone who is energized by getting things done — someone who takes real pride in execution and loves being the person who has it handled. This role is fully in-person, 5 days a week, at our Flatiron office.

Requirements

1–2 years of experience in an executive support, office coordination, or operations role
Proven ability to juggle a busy calendar and coordinate logistics without dropping details.
Discretion and maturity with sensitive, confidential information
Sharp attention to the small things and the kind of pride that fixes them before anyone asks.
Genuine warmth and a love of hospitality, plus the creativity to make everyday moments feel special.
Calm under pressure and comfortable with last-minute changes and competing priorities.
An operator's instinct: you'd rather build a system than scramble the same fire twice.
You take real pride in being the person who has it handled.
You read a calendar a few moves ahead, you notice the supply closet is running low before anyone mentions it, and you get quiet satisfaction from a day where everything ran smoothly because you made it run smoothly.
You're equally happy nailing the logistics of a CEO's week and dreaming up the small touch that makes someone's birthday actually feel special.
You want to help build a place people love coming to — and you'd rather be in the room than behind a screen.

Responsibilities

Manage a busy, shifting calendar — scheduling, rescheduling, and flagging conflicts before they become problems.
Coordinate travel end to end: flights, accommodations, ground transport, and itineraries so the CEO can step off a plane and into the next thing.
Help manage the CEO's inbox: triage communications, prep meeting materials, and keep things moving.
Handle sensitive and confidential information with care and discretion.
Take on ad hoc administrative tasks with good follow-through and instincts about when to ask and when to just handle it.
Stay reachable for urgent matters and stay calm when plans shift.
Own everything that makes the office run: vendors, supplies, maintenance, deliveries, and building relationships.
Keep the kitchen, common areas, and shared spaces organized, stocked, and guest-ready every day.
Coordinate logistics for team visitors, from meeting setup to in-office hospitality.
Support the planning of team events, celebrations, and in-office rituals that build connection.
Handle new hire day-one setup and welcome experiences so every person feels at home from the start.
Surprise and delight the team with thoughtful touches — birthdays, milestones, or just because.
Help track facilities and team experience budgets.
Keep looking for small ways to improve the space and the systems that keep it running.
