About XFX

XFX is infrastructure for capital-efficient FX — the general settlement layer for programmable finance. Money should move with the same speed and efficiency as information; today, trillions sit idle just to guarantee execution. That idle capital is the Capital Tax, and it accounts for roughly 80% of the cost of FX globally. XFX compresses it: every trade clears at fair value or better, routes through deeper liquidity than any single venue offers, and settles delivery-versus-payment — meaning capital moves only when trades do. No pre-funding. No nostro accounts. No correspondent intermediaries holding your money. Compounded across a balance sheet, that's a structurally different cost of capital.

Since launching in September 2025, XFX has grown to $7B in annualized volume, with customers trading on ~80% of days since activation. We're a small, high-conviction team of operators backed by Castle Island Ventures, Haun Ventures, Oak HC/FT, Coinbase Ventures, MAYA Capital, Paxos, and Bitso, moving toward Series B.

The role





You'll partner closely with the CFO to build and run the financial backbone of XFX. You'll own finance operations across accounting, treasury, tax, and financial systems, ensuring the monthly close, tax compliance, and day-to-day financial operations run smoothly across multiple entities and jurisdictions.

This isn't a traditional accounting role. We're looking for someone who enjoys building from scratch—designing scalable processes, automating repetitive work, and leveraging AI and modern tools to help finance scale through systems, not headcount.

As a lean team, you'll wear multiple hats across accounting, treasury, operations, and special projects. You'll have significant ownership from day one and direct visibility into how a cross-border fintech builds its financial infrastructure.
