Senior Software Engineer - Securities

At Paxos, we are creating the infrastructure for a new, open financial system - one that anyone can access and participate in, and that operates efficiently. Join a world-class team using modern high-productivity tools (Golang, Java, AWS EKS Kubernetes, gRPC, AWS KMS Kafka, AWS Aurora, Hashicorp Vault) to build a highly available, scalable, and performant API platform for crypto custody, trading, transfers, tokenization and compliance along with backend systems for securely managing billions of dollars of assets.There are billions of people in the world who are unbanked or underbanked, and trillions of dollars that are locked up because of the inefficiencies of the legacy system. We envision a new system that allows any asset to move instantaneously, anywhere in the world - to unlock the potential of assets and people everywhere. Our customers include some of the biggest enterprises in the world like PayPal, Credit-Suisse and Societe Generale, and together we are upgrading the global financial system using modern blockchain and crypto technology.
