Sr. Accountant

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.

• Maintain accuracy and integrity of the general ledger; research and resolve variances
• Assist with balance sheet reconciliations and supporting schedules
• Contribute to internal controls, process documentation, and audit support as needed

Own the full collections cycle for a portfolio of customer accounts, following a structured dunning cadence (pre-due reminders through escalated past-due follow-up)

Proactively communicate with customers regarding outstanding balances, payment plans, and disputed charges, partnering with Sales and Customer Success to resolve account-level collection issues and escalate at-risk accounts

Respond to customer requests for W-9s, invoices, statements, tax exemption documentation, RFP requests, and other standard billing information

Ensure invoices are accurate, timely, and compliant with customer-specific billing requirements (POs, portals, formats) and maintain accounting and AR workflows

Conduct preliminary accounting research and diligence

Other duties as assigned, reflecting the evolving needs of a scaling finance organization

Required Qualifications

Bachelor's degree in Accounting, Finance, or a related field (or equivalent practical experience)
