Accounts Payable Assistant

Position Summary

Atlas Supreme is a dynamic full-service general contractor, construction manager, and owner's representative delivering projects of varying scale and complexity — from fast-paced commercial fit-outs to ground-up condominiums and sustainable retrofits for affordable housing. As a growing firm with a robust portfolio, we offer an ideal environment for professional growth and hands-on learning.

The AP Assistant is the primary point of contact for Atlas Supreme's subcontractors and vendors throughout the accounts payable process. This is an in-office, communication-focused role where you'll spend much of your day speaking with subcontractors and vendors by phone and email, guiding them through the invoice submission process, collecting required documentation, and ensuring payment requests are complete before they reach the Finance team. While the AP Assistant does not process or approve payments, they play a key role in preventing delays through organization, attention to detail, and proactive communication. This position reports to the AP/AR Specialist with a dotted-line relationship to the Principal.
