Job description

Thayer Design Build is looking for an experienced in-person Office Manager to own our bookkeeping, HR administration, and a wide range of office responsibilities.

This is not an entry-level administrative role and is fully in-office. We need someone who knows their role, takes ownership, catches details other people miss, and gets things done without needing constant direction.

What You’ll Own

• Manage QuickBooks and maintain accurate financial records
• Accounts payable, accounts receivable, reconciliations, and financial reporting
• Maintain accurate project job costing
• Manage and understand Work in Progress (WIP) reporting
• Catch discrepancies and make sure costs are assigned correctly
• Support month-end and year-end close
• Coordinate with our CPA, payroll provider, and other financial partners

You do not need construction industry experience, but you must have real professional experience owning bookkeeping responsibilities for a business. You should understand bookkeeping at a higher level than simply entering transactions.

HR + Compliance

• Manage employee records and HR documentation
• Handle onboarding and offboarding
• Coordinate payroll, benefits, PTO, and employee paperwork
• Maintain HR compliance records and required documentation
• Perform regular audits to make sure files, forms, and processes are accurate and complete
• Track deadlines and make sure important paperwork does not fall through the cracks

You must have professional experience handling HR administration and compliance for a business, but official HR accreditation is not required.

These are your primary areas of ownership, but this is a small and growing company. There is always plenty to do.

You may also help with office systems, insurance, vendor coordination, reporting, paperwork, special projects, administrative work, and whatever else helps the company operate better.

We are looking for someone who sees work that needs to be done and helps get it done, not someone who stays narrowly inside a job description.

We’re Looking for Someone Who

• Has strong bookkeeping experience and advanced QuickBooks knowledge
• Understands job costing and WIP
• Has real HR administration and compliance experience
• Is exceptionally organized and detail-oriented
• Is trustworthy with sensitive financial and employee information
• Is a self-starter who takes ownership
• Has high personal standards and follows through
• Is hungry, humble, and smart
• Enjoys working hard and being part of a productive team
• Has excellent professional references

You should be the person who dots the i’s, crosses the t’s, catches the loose ends, and makes sure things actually get finished.
