Rex is seeking a Senior Manager of Treasury Operations to build and own the treasury function across a multi-entity platform. This is a zero-margin-for-error mandate:
Rex moves millions across dozens of banking relationships and hundreds of accounts, and any shortfall, bounced wire, or tightening covenant must reach leadership immediately, alongside the fix. Radical candor is the operating standard, not a nice-to-have. Reporting to the Head of Finance, this role is for an operator who wants to design the treasury infrastructure a scaling platform needs, not inherit someone else's spreadsheet.

Three mandates anchor the role. First, multi-entity cash control and fraud defense: real-time daily cash positioning across every deal and operating company, with dual controls, strict callback protocols, and bulletproof positive pay protecting every transfer. Second, investor servicing and regulated entity discipline: capital calls, preferred return payouts, and promote splits with clean distribution reconciliations across 300+ investors, while keeping insurance and fiduciary capital strictly segregated across a captive insurance structure and Rex's tech and real estate operating companies.

Third, treasury modernization: replacing manual reconciliation with API bank feeds and AI-leveraged tooling, building rolling liquidity forecasts that account for real-time Cap Ex burn and debt service, tracking agency debt covenants and DSCR tests without a dedicated underwriter, and optimizing treasury and ERP platforms (Trovata, Kyriba, Yardi, Net Suite) to keep the function lean as the entity list grows. The ideal candidate has 7 to 12 years of treasury or multi-entity cash management experience, has run complex cash operations through at least one full rate cycle, and won't be learning treasury controls on the job.

A CPA, CTP, or relevant Master's is preferred, signaling the accounting and balance sheet rigor multi-entity structures demand. This role carries dual-authorization wire authority and requires a clean background and credit history, non-negotiable given the capital under management. Beyond credentials, this is a builder who leverages AI and automation to eliminate manual work, prioritizes operational safety and liquidity over squeezing the last…
