Office Administrator

Office Administrator — Part-Time | Phoenix Business Computing Location: Hooksett, NH (In-Office Required) Type: Part-Time, 15 hours/week | $20/hour, Hourly, Non-Exempt

About Us

Phoenix Business Computing is a database consulting company based in Hooksett, NH. We're a small, tight-knit engineering team that moves fast and takes our work seriously. We're looking for an experienced Office Administrator to keep operations running smoothly and take real ownership of the administrative side of the business, so our engineers can stay focused on what they do best.

About the Role

This is a hands-on, in-office role. You'll be the operational backbone of a small company: managing supplies, supporting HR and finance processes, and helping coordinate hiring and onboarding as we grow. The schedule is flexible within our core hours, making this a great fit for someone looking for meaningful part-time work with real responsibility.

You'll work closely with the Principal Engineer/CTO, but we expect you to operate with a high degree of autonomy. Make decisions, set expectations with the team, and escalate only when it matters.

What You'll Do

Office Operations

• Keep the office fully stocked with supplies (snacks, beverages, paper goods, cleaning supplies)
• Manage weekly inventory and place Amazon orders on days you're in the office
• Handle weekly trash and recycling runs
• Coordinate with vendors for cleaning, maintenance, and seasonal services
• Act as the primary point of contact for day-to-day office issues

Finance & Administration

• Log in to Xero weekly to reconcile outstanding balances
• Match receipts to bank statements and maintain clean expense records
• Process biweekly vendor payments and support basic accounting workflows

HR & Benefits Support

• Manage employee PTO tracking and records in Calamari
• Coordinate benefits enrollment and ongoing updates with our insurance carriers
• Maintain the Employee Handbook and internal HR policies
• Handle sensitive employee and financial information with discretion

Hiring & Onboarding

• Assist with interview scheduling and candidate coordination
• Conduct initial phone screens using prepared questions
• Support Day 1 onboarding: hardware setup, system access, and new hire documentation

Team & Culture

• Plan and coordinate monthly company lunches
• Help coordinate venues and logistics for our annual company offsite
• Contribute to a welcoming, well-organized office environment

What We're Looking For

• 3+ years of experience in office administration, operations, or office management
• Small company or startup experience is a plus
• Comfortable with Microsoft Outlook and Teams
• Some background in HR, benefits administration, or payroll coordination preferred
• Highly organized, detail-oriented, and trustworthy with confidential information
• Self-directed, with the confidence to make judgment calls independently

Schedule & Compensation

• 15 hours/week, in-office at our Hooksett, NH location
• Flexible scheduling within core business hours — we're open to hours that work for your life
• $20/hour, hourly non-exempt

Why Join Us
