• Administer Ramp, including corporate card programs, expense policies, approval workflows, spend limits, and compliance monitoring.
• Partner with our external accounting firm to manage the monthly close process, review reconciliations and accruals, and ensure accurate and timely financial reporting.
• Oversee the day-to-day relationship with our accounting partner, including deliverables, service expectations, process improvements, and accountability.
• Develop and implement financial policies, internal controls, and standard operating procedures to improve accuracy, consistency, and operational efficiency.
• Manage accounts payable reporting, vendor onboarding, and contract tracking, ensuring timely payments and visibility into financial obligations.
• Maintain accurate financial records and support improvements to our general ledger, chart of accounts, and accounting workflows.
• Provide weekly visibility into cash balances, receivables, payables, and collection trends to support cash forecasting and financial planning.
• Own and optimize financial systems and integrations, including QuickBooks, Rippling, Ramp, Lithic, and Salesforce-related workflows.
• Support audit preparation, tax compliance, financial diligence, and other strategic finance initiatives as the company grows.

About you:

• 4–6+ years of experience in accounting, finance operations, or a related field, with hands-on experience managing or owning the monthly close process.
• Strong background in accounts receivable, invoicing, collections, and cash reconciliation, with a demonstrated ability to improve collection performance and reduce DSO.
• Experience overseeing outsourced accounting firms, bookkeepers, or other third-party financial service providers.
• Hands-on experience administering payroll through Rippling or a comparable platform such as ADP or Gusto.
• Proficiency with QuickBooks and Ramp or similar accounting and spend management platforms.
