Fractional Director of Finance/Head of Finance

As Fractional Director of Finance at the Aztec Foundation, you lead the finance function end to end for a Swiss foundation advancing open-source, programmable privacy on the decentralized web. Reporting to the Executive Director, you own financial strategy, planning, controls, treasury, and reporting for a globally distributed nonprofit operating at the intersection of open-source software, cryptography research, and digital assets. This is a hands-on role for someone comfortable navigating the accounting and regulatory complexity of crypto-native operations.

What you'll do

• Own the Foundation's financial strategy, annual budgeting, forecasting, and long-range planning, translating mission priorities into a sustainable financial plan.
• Establish and maintain robust accounting, internal controls, and financial policies appropriate to a nonprofit handling both fiat and digital assets.
• Lead treasury management, including custody, liquidity, and risk management of crypto and fiat holdings in line with the Foundation's risk appetite and governance.
• Lead treasury token accounting, vesting and lockup administration, and implement and operate token custody solutions.
• Oversee month-end close, consolidated reporting, audits, and preparation of financial statements to Swiss foundation and digital-asset accounting standards.
• Design and administer the financial operations behind grants and ecosystem funding, ensuring disbursements are tracked, compliant, and auditable.
• Manage tax, statutory filings, and regulatory compliance across the jurisdictions in which the Foundation operates, working with external counsel and advisors.
• Partner with the Executive Director and COO on financial modelling, scenario planning, and decisions on research funding, grants, and headcount.
• Report on financial health and controls to the board and key stakeholders with clarity and rigor.

What you bring

• 10+ years of progressive finance experience, including senior leadership of a finance function such as Head of Finance, Finance Director, Controller, or comparable role.
• A professional accounting qualification such as CPA, ACA, ACCA, CIMA, or equivalent, and deep command of financial controls, reporting, and treasury.
• Experience in a blockchain, Web3, or crypto-native organisation.
• Experience with digital assets and crypto accounting, custody, and treasury practices.
• A builder's mindset: comfortable operating hands-on in a lean, fast-moving environment.
• Strong judgment on risk, compliance, and multi-jurisdictional operations, with the ability to work alongside legal and tax advisors.
• Excellent communication skills and the ability to make financial matters clear to technical and non-technical stakeholders alike.
• Alignment with the Foundation's mission and values around privacy, open source, and user freedom.

Nice to have

• Experience standing up finance for an early-stage or newly launched entity.
• Exposure to international governance and cross-border tax structuring.

What we offer

• The opportunity to shape the finance function of a mission-driven foundation at the frontier of privacy technology.
• A remote-first, globally distributed team of world-class cryptographers, engineers, and operators.
