Sr. AR Specialist / Office Coordinator

Full-time | ~$65,000 / yr. + benefits. | On-site

Industry: Construction

Are you an experienced AR professional who knows what a strong billing process should look like—not someone who simply follows one?

We’re seeking a hands-on Senior Accounts Receivable Specialist to become the primary onsite billing and AR resource for a growing infrastructure construction operation in Denver. This is an opportunity to take real ownership, work directly with project managers and field operations, and help bring greater consistency to a project-driven, multi-entity billing environment.

What You’ll Do

• Manage construction billing and day-to-day accounts receivable activities
• Work with project managers to obtain complete billing documentation and validate billable amounts
• Prepare project-based, progress, and milestone invoices
• Reconcile customer accounts and resolve discrepancies or short-pays
• Support collections, cash application, aging, revenue reporting, and month-end activities
• Identify process gaps and help strengthen billing procedures and internal controls
• Coordinate routine office needs and support the administrative side of new-hire onboarding

What We’re Looking For

• 3+ years of progressive AR and billing experience; senior-level depth is strongly preferred
• Strong understanding of full-cycle AR, including invoicing, reconciliation, collections, cash application, and aging
• Construction, utilities, infrastructure, engineering, or other project-based billing experience preferred
• Strong Excel and general ERP experience
• Confident, organized, and comfortable following up with busy project managers
• Able to ask questions, recognize missing information, and carry issues through to resolution
• Willing to balance specialized AR responsibilities with practical office support

ComputerEase experience and English-Spanish bilingual skills are helpful but not required.

Why Consider It?

You’ll have meaningful ownership of a visible AR function, direct access to leadership, and the opportunity to improve processes as the organization continues to grow. This is an onsite individual-contributor role with a private office and a controller who values direct communication, good ideas, and respectful pushback.

If you’re an experienced AR professional who enjoys making processes work better—and you’re comfortable partnering with both accounting and construction operations—we’d like to hear from you.
