About the role
The Senior Accountant is a broad-based accounting role responsible for month-end close, general ledger accuracy, and reconciliations, while also owning the company's accounts receivable function (invoicing, collections/dunning, customer billing inquiries, and basic sales tax/VAT support) across US and international markets. This role is well suited to someone who wants both technical accounting depth and hands-on ownership of a customer-facing process. The Senior Accountant reports to the Controller and works cross-functionally with FP&A, Sales, Customer Success, and outside tax advisors.
This is a detail-oriented, technology-forward role. The ideal candidate is comfortable using AI tools to improve efficiency and accuracy across accounting and AR workflows, and communicates clearly and professionally with customers and internal stakeholders.
