Senior Software Engineer, Blockchain

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 Blockchain Engineering team is responsible for building and maintaining the core infrastructure that powers Paxos’ issuance of tokenized assets. Our engineers are passionate about designing and implementing secure, scalable, and high-performance systems that ensure the seamless creation, management, and transfer of digital assets. We work closely with product, operations, and compliance teams to drive innovation in financial technology while maintaining the highest standards of reliability and security.
