Job description

Who We Are

We’re Pinnacle — an experiential marketing house. Strategists, creatives, builders, and your future besties, all fueled by the same pursuit: we’re never satisfied. Our name is an ambition. We chase down the next “holy smokes, they actually did that” moment. And then, we do it again.

The Role

We are recruiting for a high powered, extra resourceful, incredibly organized and all around rad Office Administrator to wrangle the exciting, fast-paced chaos in our Irvine, California facility.

What You’ll Do

• Keep the building humming behind the scenes—paper stocked, printers ready, coffee brewing, and supplies on hand
• Coordinate shipping and mail, including preparing labels, handling deliverires, and reviewing FedEx invoices
• Monitor inventory and order office, kitchen, and coffee supplies so that we have what we need when we need it
• Coordinate some building and equipment repaires, replace printer toner, and work with vendors for copier, phone, janitorial, and other facility services
• Take ownership of the role and pride in the space – notice what needs attention, jump in where you can help, and bring a positive, collaborative approach to the people around you
• Provide a variety of administrative support to our sales, HR, and operations teams, including data entry, database updates, and responding to client and account team requests
• Prepare conference rooms for client visits and meetings, including refreshments, supplies, and tidying up afterward
• Answer phones, respond to general inquiries, and welcome clients and visitors with a friendly, helpful approach
• Process routine purchasing requests and purchase orders, and help maintain accurate inventory records
• Book travel and assist with arrangements for employees and project teams
• Keep shared spaces clean, organized, and welcoming, including kitchens, conference rooms, and common areas
• Plan our employee parties, events, and team lunches
• Help create and share office communications, with opportunities to dabble in creative projects

Who You Are

• You’ve got strong administrative and organizational skills and enjoy keeping things on track in a busy, fast-paced office
• You’re all about the details. You double check, triple check, and catch the little things before they become bigger things
• You can pick up where you left off after a phone call, delivery, or “quick question” – and manage your time to meet multiple deadlines
• You bring at least two years of administrative experience, and you actually love this kind of work!
• You know your way around Microsoft Office (Word, Excel, Outlook and presentation programs); familiarity with Adobe Creative Suite
• You keep your cool when things get hectic and know that confidential information stays confidential
• You’re a clear, friendly communicator—whether you’re writing an email, answering the phone, or helping someone in person
• You’re dependable, competent, helpful, and ready to pitch in, we can count on your to be here and ready to go, Monday-Friday, 8:00 am to 5:00 pm

Not For You If…

• You need someone else to organize your day and remind you of deadlines
• Answering phones, restocking coffee, or tidying shared spaces feels beneath you
• You aren’t open to feedback or learning from mistakes
• Details and proofreading feel like unnecessary extras
• You prefer a quiet, predictable workday with few interruptions
• You don’t particularly enjoy administrative work—because around here, it’s the heart of the job!

We look forward to hearing from you!
