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

Success in this role means:
