About this role
In Renaissance Florence, wealthy merchants faced a dilemma: where could they safely store their gold without it sitting idle. The Medici family offered a radical alternative. Deposit your assets with them and your assets would be secure, earn consistent returns, and, crucially, be accessible when needed. It was one of the first smart options for wealth: safe, productive, and liquid. The spirit of innovation and financial ingenuity that defined Renaissance Florence finds a powerful echo in the modern startup world.
Mercury brings that same spirit to building an exceptional banking\* experience for all. Our Treasury team builds the answer founders are looking for what to do with their idle cash. We’ve created a financial platform that helps startups put their idle cash to work. It helps startups manage their cash with confidence, combining safety and yield in one elegant package. Think of it as institutional-grade cash management, reimagined for ambitious startups.
The Treasury team is a team of full-stack engineers that are building thoughtful products that manage billions in customer funds, all while helping Mercury scale. We operate with a high degree of quality and care because we understand today's startups, like their historical counterparts, require solutions that go beyond.
