Reports to: [Controller / Finance Manager]

Department: Finance / Accounting

Location: [City, State] — [On-site / Hybrid / Remote]

Employment type: [Full-time]

Allwater is a growing organization where the finance team is building a modern, technology-forward back office. We are investing in automation and artificial intelligence to make our accounts payable, procurement, and vendor management processes faster, more accurate, and more scalable. This role sits at the center of that effort.

We are seeking a detail-oriented Accounts Payable Specialist to own the day-to-day AP function and help modernize how we manage payments, purchase orders, corporate cards, and vendor relationships. The ideal candidate is hands-on with a modern spend-management platform such as Ramp or Rippling, is energized by using AI and automation to eliminate manual work, and is comfortable supporting the broader finance function — including stepping in to assist Accounts Receivable and collections when needed.

This is a high-impact seat for someone who wants to help shape efficient, forward-looking finance operations rather than simply process invoices.

• Create and maintain accurate vendor profiles and master data within the AP/ERP system.
• Collect, verify, and track required vendor documentation, including W-9s and Certificates of Insurance (COIs), and follow up to keep records current and compliant.
• Support 1099 preparation and year-end reporting by maintaining clean, complete vendor records.

• Champion the use of AI and automation to streamline invoice capture, coding, approvals, and reconciliation, reducing manual effort and error.
• Identify process improvement opportunities and help implement, test, and refine automated workflows within our AP and spend tools.

• Support the broader finance function with month-end close activities, accruals, reconciliations, and reporting as needed.
• Assist Accounts Receivable and collections efforts as needed — including customer follow-up, applying payments, and helping resolve outstanding balances.
• Respond to internal and vendor inquiries professionally and maintain strong working relationships across the organization.

• 2+ years of accounts payable, bookkeeping, or general accounting experience.
• Hands-on experience with a modern spend-management or AP automation platform such as Ramp or Rippling (or comparable, e.g., , Airbase, Brex), including corporate card management.
• Working knowledge of purchase order processes and three-way matching.
• Experience maintaining vendor records and collecting compliance documents such as W-9s and COIs.
• Strong attention to detail, organization, and accuracy with numbers and documentation.
• Comfort with technology and a genuine interest in using AI and…
