Compensation: $55k-$65k base + performance bonus

Employment Type: Full-Time

Role:

Corrosion Services, LLC is a leading provider of cathodic protection design, installation, and service for water storage tanks, pipelines, and other critical infrastructure.

We are hiring a Construction Office Manager to take ownership of the company’s finance and compliance work.

This is not a general administrative assistant role, this is a high-trust role inside a small, quickly growing company. You will work directly with ownership, take responsibility for critical business systems, and help build the administrative foundation the company will grow on.

The day-one need is payroll, AR/AP, bookkeeping support, and compliance coordination. The growth path is ownership of the company’s back-office operations, project administration, document control, reporting, and building internal systems.

We are a small company, which means not every system is already built. That is the challenge and the opportunity. We need someone who is organized, detail-oriented, hungry, and comfortable creating order where it does not yet exist. You will receive the current SOPs, templates, and file paths during handoff.

Performance bonus will be tied to first pass compliance approval, clean AR/AP cadence, value created, and the degree to which this person reduces owner involvement in recurring administrative work.

Results:

In the first 30 days you:

· Take over weekly time-entry cleanup and payroll prep.

· Build the compliance calendar for active projects.

· Submit or support certified payroll submission on time.

· Build AR/AP status by project.

· Put QuickBooks bookkeeping support, bills, receipts, and filing on a weekly cadence.

· Give the owner a clear view of deadline risk, receivables, payables, and compliance status.

Requirements:

You must have payroll, AP/AR, and QuickBooks experience related to construction, engineering, or other service-based business operations.

Strong candidates have:

· Public construction project payroll experience.

· High detail control with dates, forms, job coding, pay items, project files, and recurring deadlines.

· Experience with AR/AP, billing, invoice tracking, receipts, and payment follow up.

· Prevailing wage and wage classification knowledge.

· Strong written communication and follow-up skills.

· Buy America, BABA, insurance, licensing, or project compliance exposure.

This is not a dead-end office job. We are looking for someone hungry, organized, and motivated to grow with the company. The right person will take ownership of their work, build systems that support growth, and become increasingly valuable as the company grows.
