About Paxos

Today’s financial infrastructure is archaic, expensive, inefficient and risky — supporting a system that leaves out more people than it lets in. So we’re rebuilding it.

We’re on a mission to open the world’s financial system to everyone by enabling the instant movement of any asset, any time, in a trustworthy way. For over a decade, we’ve built blockchain infrastructure that tokenizes, custodies, trades and settles assets for the world’s leading financial institutions, like Mastercard, Visa, Robinhood, and Pay Pal.

The Experience Platform team is on a mission to enable a best-in‑class unified and fully self‑service platform product experience for our customers. We drive core initiatives around self‑serve provisioning, governance, and platform usage while providing shared libraries and components to ensure a reliable, secure and agile experience across Paxos services. Our team is at the forefront of transforming how customers interact with Paxos' products through intuitive interfaces and robust API solutions.

As a Software Engineer on the Experience Platform team, you'll play a crucial role in building and evolving Paxos' unified platform experience. You'll work on challenging projects involving user authentication, access control systems, and self‑service capabilities that directly impact our customers' ability to manage their digital assets efficiently. This is an opportunity to shape the future of financial infrastructure while working with modern technologies and solving complex technical challenges at scale.
