Join the Subsurface Team

We’re Hiring an Office Administrator – Smithfield, NC

This is not a remote or hybrid administrative role.

At Subsurface, the Office Administrator is responsible for supporting payroll, accounts payable, and administrative processes while managing the daily needs of the office. This person helps ensure that employees, visitors, vendors, and leadership can rely on an organized, professional, and well-maintained workplace.

This is a 100% in-office position. Consistent physical presence in the Smithfield office during normal business hours is an essential function of the role because the position is responsible for supporting employees and visitors, receiving deliveries, managing office supplies, coordinating housekeeping, and maintaining the daily readiness of the workplace.

If you take pride in keeping details organized, supporting others, and creating an office environment where people have what they need to work effectively, keep reading.

If you are seeking a remote or hybrid work arrangement, or prefer to wait for others to identify what needs attention, this role is not for you.

The Mission

Your mission is to keep the office, payroll, accounts payable, and administrative support functions organized, accurate, stocked, and ready to support the business every day.

Success in this role means:

• Payroll information is processed accurately and on time.
• Accounts payable documentation is organized and entered correctly.
• Employees, visitors, vendors, and leadership receive responsive and professional support.

• Housekeeping and office service needs are coordinated and promptly addressed.
• Common areas, conference rooms, kitchens, and reception spaces remain clean, organized, and visitor‑ready.
• Administrative and financial records are complete, orderly, and confidential.
• Office needs are identified and addressed before they disrupt the workplace.

Completing assigned administrative tasks while allowing the office environment or employee support needs to be neglected is failure.

Who This Role Is For

This role is for someone who:

• Is honest when handling payroll, financial records, employee information, and company resources.
• Is respectful when supporting employees, visitors, vendors, and leadership.
• Is self‑motivated and addresses office needs without waiting to be told.
• Applies creative problem‑solving to administrative and workplace challenges.

• Is reliable in attendance, accuracy, organization, and follow‑through.
• Is fair and consistent when applying administrative procedures and supporting employees.
• Takes pride in maintaining a professional, welcoming, and well‑organized office.
• Understands that stocking supplies, coordinating housekeeping, and maintaining common areas are essential responsibilities of the position, not occasional secondary tasks.

You perform best when:

• Expectations are clear.
• Details matter.
• Organization is maintained consistently.
• Follow‑through is expected.
• You are physically present and actively engaged in the daily needs of the office.
• Problems are addressed proactively rather than left for someone else.

What You Will Do

• Maintain a professional, organized, clean, and welcoming office environment.
• Work 100% in the Smithfield office during established business hours.
