Job description

MAVI places experienced finance and accounting professionals into senior, high-ownership roles at high-growth US companies. Founded in 2023 and backed by a $4 million seed round led by Harlem Capital, MAVI was recently featured in TechCrunch.

Our professionals join in-house finance teams in full-time, long-term roles, not short-term projects. The companies we work with range from venture- and PE-backed businesses to public companies and CFO advisory firms, including Athena Club, MotherDuck, and Within.

The work centers on judgment. As AI takes over more transactional accounting, the people who review the output, question it, and own the result matter more than ever. MAVI professionals work alongside US finance leaders, using AI tools to do more and applying the judgment to catch what those tools get wrong. At one client, an AR dashboard now used across the organization was built almost entirely by MAVI talent.

We stay involved throughout, from role alignment and interview preparation to onboarding and long-term career development.

The Role

We are seeking a Senior Accountant to own the month-end close and core financial reporting at a US fintech company, working remotely from Argentina.

You will own your workstream end to end with light review, working directly with the Controller or Accounting Manager. Where the process relies on manual workarounds, you will be expected to fix it rather than repeat it.

The role sits close to the parts of the business that make a US fintech company different, so the accounting and analysis reflect how the sector actually works.

What You'll Own

• The close. Prepare and own month-end close tasks, including accruals, prepaids, and balance sheet reconciliations.
• Financial statements. Prepare the P&L, balance sheet, and cash flow support under US GAAP, and explain material movements.
• Journal entries. Record recurring and non-recurring entries with support a reviewer can follow.
• Funds flow. Reconcile processor, bank, and ledger balances daily, including settlements and chargebacks.
• Partner reporting. Support reporting for sponsor banks, licenses, and partner audits.
• Audit support. Prepare the PBC schedules for your areas and answer auditor questions directly.

What We're Looking For

• 4+ years of accounting experience
• Experience owning a workstream through the close without day-to-day supervision
• Solid accrual accounting fundamentals and experience preparing financial statement support
• Experience with high-volume transaction reconciliations
• US GAAP experience, or strong Argentine GAAP (FACPCE) or IFRS experience with exposure to US clients or entities
• Experience with QuickBooks Online, NetSuite, Sage Intacct, or Xero
• Strong written and spoken English for daily work with US teams
• Bachelor's degree in Accounting, Finance, or a related field, or an equivalent professional qualification

Preferred

• Big 4 or public accounting experience, or experience serving US clients
• Experience with Stripe, Adyen, Marqeta, or similar platforms
• Experience using AI tools in accounting workflows, with the judgment to review and correct AI-generated output

Who This Role Is For

An accountant ready to own a workstream outright, who cares about why a number moved and raises issues before anyone else finds them. Experience in fintech matters here: you will spend less time learning how the business makes money and more time improving how it is measured.

Why Join Through MAVI

• Own the month-end close and core financial reporting for a US fintech company, working directly with US finance leadership
• Full-time, long-term placement, with MAVI handling cross-border contracts, compliance, and payroll
• USD-denominated compensation aligned with experience and scope
• Progress toward Lead Accountant and Accounting Manager opportunities through MAVI

Work Arrangement

This is a fully remote role with a single client company for the duration of the engagement. Full-time roles require a minimum of 4 hours of daily overlap with US Eastern Time (ET); part-time roles require a minimum of 2 hours.
