• Prepare and post journal entries for accruals, reclasses, and other general ledger activity in alignment with GAAP.
• Perform monthly reconciliations for key balance sheet accounts such as cash, AR, AP, and accruals.
• Support month-end and year-end close processes to ensure financial accuracy and completeness.
• Collaborate cross-functionally to resolve billing, payment, and account discrepancies.
• Assist in audit preparation by providing schedules and supporting documentation.
• Identify and implement process improvements to enhance O2C and AP efficiency and accuracy.

What You’ll Bring:

• 3+ years of relevant accounting experience, ideally with exposure to O2C, AP, and journal entries—or experience at a Big 4 firm.
• Solid understanding of GAAP and the ability to apply principles to real-world transactions.
• Experience with ERP/accounting systems preferred (e.g., Sage Intacct, Bill.com).
• Proficiency in Microsoft Excel (e.g., pivot tables, VLOOKUP).
• Strong analytical, organizational, and communication skills with a proactive, problem-solving mindset.
• High attention to detail and ability to meet deadlines in a dynamic, fast-paced environment.
• CPA or CPA track is a plus.
• Experience supporting SaaS business model from product launch to the full O2C process.

What You’ll Get:

• Competitive salary and comprehensive benefits package.
• Exciting opportunities for career growth within a rapidly expanding company.
• Remote-first flexibility
• A collaborative, mission-driven team environment.
