Accounting Operations Associate

1–3 years of experience in accounting, bookkeeping, or a related finance role, with meaningful hands-on AP/AR experience.

Exposure to treasury or cash management tasks (bank transfers, cash positioning, reconciliations) — direct treasury experience is a strong plus, not a requirement.

Experience administering or power-using financial systems (e.g., an ERP, AP/AR platform, or banking portal) — comfortable owning a system, not just using it.

Strong Excel/spreadsheet skills and comfort working across multiple financial systems.

Strong attention to detail and follow-through on recurring, deadline-driven, controls-sensitive work.

Clear communicator, comfortable working with vendors, customers, banks, and internal teams.

A systems/process mindset — someone who naturally looks for ways to make financial operations more accurate and efficient.

Interest in growing beyond AP/AR into broader accounting, treasury, and finance operations.

No certification required; degree in accounting, finance, or related field preferred but not mandatory.

Experience at a startup or fast-growing company.

Prior exposure to treasury management systems or online banking platforms.

Prior experience owning/administering a financial system beyond AP/AR (e.g., ERP, payroll, or expense tools).
