Job description

Office Manager (Part-Time) – Greenlee Construction

About Us

Greenlee Construction is a licensed commercial general contractor based in North Charleston. We build tenant fit-outs and renovations for retail and commercial clients across the Southeast. We’re a small team that’s growing fast, and we need someone in the office to keep the back end organized so our project team and crew can stay focused on building.

The Role

This is a part-time, in-person position at our office on Industry Drive. You’ll be the go-to person for bills, payments, paperwork, and keeping things moving day to day. We use JobTread for project management and job costing, and it’ll be a big part of your day.

What You’ll Do

• Manage the company accounting inbox and get vendor and sub invoices entered into JobTread
• Track bills through approval and process vendor payments
• Keep JobTread and QuickBooks in sync, working with our outside CPA
• Collect and track subcontractor compliance docs like COIs, W-9s, and lien waivers
• Help keep our WIP schedule up to date
• Monitor bid platforms and flag new opportunities
• Answer phones, handle mail, order supplies, and keep the office running
• Track your own tasks and follow through without needing reminders

What We’re Looking For

• Office, bookkeeping, or accounts payable experience
• Construction industry experience strongly preferred. You’ll pick things up faster if you already know what a COI, a lien waiver, or a pay app is.
• Comfortable with software and willing to learn new systems (JobTread, Microsoft 365, OneNote)
• QuickBooks or JobTread experience is a plus
• Organized, dependable, and good at keeping a lot of moving pieces straight
• Able to work a regular in-office schedule

Details

• Part-time, 20-30 hours per week
• Schedule: Weekdays, between the hours of 7am - 5pm
