About the role

The Accounts Payable Manager will play a critical, hands‑on role in building and running the company’s accounts payable operations as The Nuclear Company continues to grow. As the first dedicated AP resource, this position will own the end‑to‑end payables process, invoice processing, payment execution, vendor management, expense and corporate card administration, reconciliations, and AP close with a strong focus on accuracy, timeliness, financial controls, and fraud prevention.

Working closely with Accounting, Procurement, Treasury, and business leaders, the Accounts Payable Manager will design, implement, and scale the processes, controls, automation, and reporting the function needs. As the organization moves into construction‑phase activity, this individual will stand up the project payables infrastructure—purchase order workflows, contractor payment processes, retainage, and compliance documentation required to support significantly higher volume and complexity.

Note: This is a hybrid position based in our downtown Columbia, South Carolina office. The role has been posted in Charlotte and surrounding markets for visibility, as the hybrid schedule may make the commute workable for candidates living outside the immediate Columbia area. Candidates should be within commuting distance of Columbia or open to relocation.
