Detail-Driven? Process-Obsessed? We Need You as Our Office Manager!

ROXBOX - Turning Steel Boxes into Game-Changing Spaces

You love order. You run on checklists. You’re the one who notices when something’s off—and fixes it before anyone else sees it.

You don’t just “manage an office”—you run the show. Calendars? Handled. Payroll? Already processed. Onboarding a new hire while reconciling receipts and organizing vendor paperwork? All in a day’s work. You don’t need the spotlight—you just need systems that make sense, processes that work, and a team that trusts you to keep it all moving. If you’ve ever color-coded a spreadsheet because it was the right thing to do, keep reading—you might be our next Office Manager.

ROXBOX is looking for a highly organized, resourceful, and detail-loving Office Manager to help run the day-to-day operations at our fast-paced modular manufacturing company in Houston. You’ll own the office rhythm—handling bookkeeping, HR support, and admin operations so our leadership team can stay focused on the big picture.

Proficient in QuickBooks Online, Microsoft Excel, and G-Suite

Experience with AP/AR, general ledger maintenance, bank reconciliation, expense tracking, and basic financial reporting

Ability to manage bookkeeping independently while coordinating with leadership and external accountants

Strong attention to detail and organization—you catch the things others miss

Experience handling HR/recruiting functions and with ATS platforms

Familiarity with payroll processing and benefits tracking is a strong plus

Strong communication skills—professional, proactive, and clear

Tech-savvy and systems-minded—always improving the process

What You’ll Do:

Bookkeeping Boss – Own accounts payable and receivable, reconcile bank and credit card statements, process invoices, track expenses, and prepare financial reports.

Payroll & Reporting Support – Process payroll, track PTO, assist with benefits administration, and help prepare reports for leadership and tax prep.

HR Hero – Assist with recruiting, new hire onboarding, background checks, and benefits coordination.

Culture Curator – Help organize team events, birthdays, office celebrations, and onboarding swag.
