MAVI places experienced finance and accounting professionals into senior, high-ownership roles at high-growth US companies.
Founded in **** 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 an Accounting Supervisor to own the month-end close and core financial reporting at a high-growth US company, working remotely from Argentina.
This is the senior individual contributor seat in the area: you will own the hardest reconciliations and judgment calls, review the work of others, and be the first escalation point for the team and for auditors.
What You'll Own
Close calendar.
Run the close calendar day to day and chase late inputs from outside finance.
The close.
Own the monthly, quarterly, and annual close, with accountability for the calendar, quality, and cycle time.
Financial statements.
Prepare the P&L;, balance sheet, and cash flow support under US GAAP, and explain material movements.
Process improvement.




Improve close checklists, SOPs, and recurring workflows, including where AI and automation can help.
Review and coaching.
Review entries and reconciliations prepared by others, and coach junior accountants on how to get them right the first time.
What We're Looking For
6+ years of accounting experience
Experience reviewing other accountants' work and resolving complex reconciling items
Solid accrual accounting fundamentals and experience preparing financial statement support
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 using AI tools in accounting workflows, with the judgment to review and correct AI-generated output
Who This Role Is For
A senior accountant who is the person others go to when something doesn't tie, and who wants to grow into leading a team.
