As our Office & HR Coordinator, you will be the operational heartbeat of our team. This is a highly visible, hands-on role that touches nearly every part of the business — from keeping shared spaces stocked and welcoming, to coordinating events and travel, to supporting our HR and sales operations with precision and care. You will wear many hats, and you will thrive doing it.
This role is a great fit for someone who takes pride in creating a warm, professional environment, moves quickly without sacrificing accuracy, and genuinely enjoys being the person others can count on.
What You'll DoYou'll manage inventory of office, food, and kitchen supplies, maintain shared spaces (kitchen, conference rooms, common areas), oversee vendor relationships, and distribute mail and correspondence — making sure everyone has what they need, when they need it.
You'll serve as the first point of contact for employees, visitors, candidates, vendors, and board members — greeting guests with professionalism and warmth and ensuring every person who walks through the door has a positive experience.
From weekly team meetings to all-hands sessions and offsite events, you'll manage scheduling, logistics, room booking, catering, materials, setup, and post-event follow-up — including gathering slides, sending recaps, and tracking action items.
You'll draft and send standard HR communications, coordinate onboarding activities for new employees, and maintain accurate, confidential records. Your discretion and reliability will make you a trusted partner to the HR function.
You'll manage calendars, book travel (flights, hotels, ground transportation), and assist with expense reports — keeping leadership organized and moving.
You'll manage, route, and file NDAs; set up new customers and vendors in ProShop; and ensure all required data is accurately entered and maintained.
You'll assist with processing vendor invoices, coordinate approvals, ensure timely payments, and maintain accurate accounts payable records.
Support additional projects and cross-functional needs as they arise.

Skills & Abilities
Exceptionally organized — you manage multiple concurrent priorities, meet deadlines, and maintain accuracy without being asked twice.
