The Opportunity

Rex is seeking a Head of Finance to build and lead the financial architecture for a growing ecosystem of operating companies, investment vehicles, and family office activities. Working directly with Peter Rex and senior leadership, this person will serve as the strategic financial quarterback for the organization, bringing visibility, rigor, and forward-looking judgment across an increasingly complex portfolio.

This role is anchored by three core mandates: building world-class financial visibility, creating disciplined capital allocation frameworks, and establishing the infrastructure required to support long-term growth. The Head of Finance will drive forecasting at ecosystem level and at each company, employee financial incentives, investment partner strategy, global cash management, debt strategy, tax planning and strategy, capital deployment oversight, banking relationships, investment inflows, intercompany allocations, and financial governance across multiple entities and business lines. They will build the systems and reporting frameworks that allow leadership to deploy capital intelligently, evaluate opportunities, manage risk, and see around corners before problems emerge. The ideal candidate brings 10-15 years of finance leadership experience within private equity, family office, holding company, investment management, or multi-entity operating environments. Candidates should have firsthand experience deploying capital, managing lender relationships, negotiating debt facilities and credit lines, overseeing sophisticated tax planning initiatives, and supporting complex ownership structures. Corporate accounting and fund accounting expertise needed, alongside fluency operating modern finance platforms such as NetSuite, Adaptive Planning, Anaplan, Carta, or similar systems.

This is not a delegation-heavy executive role. We are looking for a builder who is equally comfortable designing strategy and personally creating the systems required to execute it. The right candidate combines exceptional financial judgment with analytical rigor, intellectual honesty, and a bias toward simplicity. They must be capable of delivering hard truths with clarity and conviction while bringing order to highly complex environments. This role requires high agency, strong business judgment, and deep alignment with what we are building. We are looking for a trusted advisor, capital allocator, and operator capable of helping steward and scale a multi-entity enterprise over the long term. Must deeply believe in the mission. Not for mercenaries. Only for missionaries.

About the Role

This role exists to build and lead the financial architecture for a growing ecosystem of operating companies, investment vehicles, and family office activities. This role exists to give leadership clear visibility, disciplined judgment, and real-time control across a complex, multi-entity platform.

This person will work directly with Peter Rex and senior leadership as the strategic financial quarterback for the organization. They will own financial reporting, forecasting, capital allocation, cash management, debt strategy, tax strategy, governance, and decision support across companies, funds, entities, and business lines.

The Head of Finance will build the systems, models, dashboards, controls, and operating rhythms required to scale. They will turn complexity into clarity, establish disciplined capital deployment frameworks, strengthen banking and lender relationships, manage investment inflows, and ensure leadership can see risk and opportunity before they become obvious.

This is for a builder with elite financial judgment who can operate at both altitude and ground level. Strategy matters, but execution matters more. This person must bring order, rigor, and truth to the financial engine of Rex. Must be missionary to the bone.

Key Responsibilities

• Build ecosystem-level financial visibility across operating companies, investment vehicles, family office activities, and intercompany structures.

• Manage lender relationships, negotiate credit lines, evaluate debt facilities, and support long-term capital structure strategy.
• Build financial reporting packages for Peter Rex, senior leadership, investment partners, lenders, and key stakeholders.
• Oversee corporate accounting, fund accounting, intercompany allocations, consolidations, and entity-level financial governance.
• Partner with tax advisors, legal counsel, and leadership to drive tax planning, entity structuring, and ownership-related financial strategy.
• Design employee financial incentive models that align performance, ownership, and long-term value creation.
• Evaluate investment opportunities, capital deployment requests, business plans, and downside risk with clear analytical judgment.
• Implement and optimize finance systems such as NetSuite, Adaptive Planning, Anaplan, Carta, banking platforms, and reporting tools.
• Establish financial controls, approval workflows, reporting cadences, and accountability mechanisms across the ecosystem.
• Deliver hard truths quickly, clearly, and without politics when numbers reveal risk, waste, or weak thinking.
• Build a finance function that scales without becoming bureaucratic.

Ideal Candidate Profile

• 8-12 years of finance leadership experience in private equity, family office, holding company, investment management, or multi-entity operating environments.
• Proven experience managing complex ownership structures, intercompany activity, investment vehicles, and operating company financials.

• Bachelor's degree in finance, accounting, economics, or related field required. CPA, CFA, or MBA preferred but not required.
