Lithic is hiring a Senior Accountant to own the annual audit, support AP and AR activity, and drive the month-end close alongside the Accounting Manager. This role is the technical backbone of the accounting team. We encourage you to apply even if you don't meet every requirement below!

What You'll Do

• Serve as the day-to-day lead on external audit requests — managing the PBC list, timeline, and fieldwork logistics, preparing schedules, workpapers, and tie-outs, and responding to auditor inquiries.
• Own product-level cash reconciliations across network payables, customer receivables, interchange, chargebacks, and fees — ensuring every dollar movement across the card lifecycle ties out between internal ledgers, processor/network reporting, and bank statements.
• Investigate reconciliation discrepancies using transaction-level data, document root causes, and partner with Data and Engineering to resolve underlying issues.
• Review AP and AR activity — payments, employee reimbursements, card issuance, invoicing, deferred revenue schedules, and credit application.
• Prepare and review month-end journal entries — accruals, allocations, reclasses — with adequate support and approval.
• Back up the Accounting Manager on monthly close to ensure timely, accurate reporting, including variance analysis and cost-saving opportunities.
• Research and document technical accounting positions, and help maintain and enforce company policies and procedures.
• Evaluate workflows and procedures, recommending and implementing changes that increase accuracy and efficiency.
• Provide guidance and technical review to junior team members, plus support for ad hoc analyses and projects.

What You Bring

• BA/BS in Accounting with 4+ years in Big 4 and/or on a startup accounting team.
• FinTech experience preferred — familiarity with payments concepts (settlement, interchange, funds flow), or the ability to learn complex transactional data models quickly.
• Ability to write basic SQL to retrieve, filter, join, and summarize transactional data, with an investigative mindset to identify and explain discrepancies.
• Demonstrated use of AI tools (e.g., Claude) and advanced Excel to work through large, complex data sets — reconciliations, variance analysis, memo drafting, and process documentation.
• Experience working directly with auditors on an independent financial statement audit, with working knowledge of GAAP.
• Advanced ERP experience (preferably NetSuite) and hands-on AP/AR work, including subledger-to-GL reconciliation.
• Customer service-level communication skills with attention to accuracy and detail.
• Desire to succeed, adapt, and grow in a fast-paced organization, with an approachable demeanor that inspires trust.
• Experience with Salesforce, Ramp, Google Suite, and/or Looker is a plus.

The annual US salary range for this role is $89,000 - $120,000 plus equity. This salary range may be inclusive of several career levels at Lithic and will be narrowed during the interview process based on the candidate’s experience and qualifications.
