Senior Software Engineer

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 PayPal, Venmo, Mastercard and Interactive Brokers. 

About the team

The Brokerage team at Paxos enables partners to offer seamless crypto trading and custody through a fully regulated, scalable platform. We power some of the largest fintechs and enterprises, allowing them to integrate crypto services without the complexity of building and managing their own infrastructure.
