Head of Finance & Accounting

Location: Remote (Costa Rica)

About MAVI

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 Head of Finance & Accounting to lead the entire finance function of a high-growth US company, working remotely from Costa Rica.

This is the most senior finance seat in the business. You will own accounting, planning, cash, tax, and board and investor reporting, and be the person the CEO relies on to answer the question behind every major decision: can we afford it, and what does it do to the plan? You will report directly to the CEO and work closely with the board, investors, and every department head.

What You'll Own

Strategy and Stakeholders

• The finance function. Own accounting, FP&A, cash, and tax as one function, including its structure and hiring plan.
• Strategic partnership. Advise the CEO on pricing, hiring, investment, and the trade-off between growth and burn.
• Board, investors, and fundraising. Prepare board materials and investor updates, and lead financial preparation for equity or debt raises.

Planning and Cash

• Budget and forecast. Own the annual budget, rolling forecast, and scenario planning.
• Cash and runway. Own cash management, treasury, and runway planning.
• KPIs. Define and report the metrics that matter, such as ARR, gross margin, CAC payback, and burn multiple.

Accounting and Controls

• Accounting. Hold final accountability for the close and the financial statements under US GAAP, directly or through a Controller.
• Controls and compliance. Establish internal controls and delegation of authority, own the audit relationship, and oversee tax and entity compliance.
• Team and systems. Build and lead the accounting and FP&A team, and own the finance systems stack.

What We're Looking For

• 12+ years of finance and accounting experience, including leadership of both accounting and FP&A
• Experience as the senior finance leader, or deputy to the CFO, at a high-growth company
• Strong command of US GAAP, with the depth to review and sign off on a Controller's work
• Proven experience building budgets, forecasts, and three-statement financial models
• Direct ownership of cash management and runway planning
• Experience preparing and presenting board and investor reporting
• Strong written and spoken English, with the presence to lead a board or investor discussion
• Bachelor's degree in Accounting, Finance, Economics, or a related field, or an equivalent professional qualification

Preferred

• Contador Público Autorizado (CPA Costa Rica), US CPA, ACCA, CIMA, or equivalent strongly preferred; an MBA is an advantage
• Experience using AI tools in finance workflows, with the judgment to review and correct AI-generated output
• Experience supporting or leading a fundraise, debt facility, or M&A process
• Big 4, investment banking, or consulting experience followed by in-house finance leadership
• SaaS or recurring-revenue experience
• Experience with planning tools such as Adaptive, Pigment, or Mosaic

Who This Role Is For

A finance leader who wants to own the whole picture, from the ledger to the board deck, and who is as comfortable challenging a hiring plan as reviewing a consolidation.

Why Join Through MAVI

• Lead the full finance function of a high-growth US company, reporting directly to the CEO
• Work closely with founders, boards, and investors on the decisions that shape the business
• Full-time, long-term placement, with MAVI handling cross-border contracts, compliance, and payroll
• USD-denominated compensation aligned with experience and scope
• Progress toward CFO and Fractional CFO 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.
