at Paxos (View all jobs)


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. 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.

We are looking for a Senior Software Engineer to join our rapidly growing engineering team. Our current team is made up of 40+ engineers, with a range of experience in startups and technologies. Senior Software Engineers are responsible for building, implementing and scaling key features of Paxos’ products, and will influence technical decisions that impact our code-base. Every engineer, despite seniority, has the ability and opportunity to influence our product strategy by helping define the product features, refine system architecture, and spearhead best practices that enable a high quality product. A commitment to teamwork, hustle, and strong communication skills are absolute requirements.  

Paxos Settlement Service is a platform that is transforming settlement in the world’s largest equities marketplace. This $34 trillion market of US equities has operated on the same outdated technology for nearly 50 years. The Paxos platform enables participants to massively reduce the cost of settling equities trades. Paxos is achieving this revolutionary feat through its unique position as a regulated institution trusted within the traditional system while simultaneously pioneering modern technology. This new approach has been actively covered by major US press:

Wall Street Journal



Being a part of this initiative you will be instrumental in bringing the current pilot into the future as a scalable solution that brings competition to the US Equities settlement market for the first time in nearly 50 years. If you are an advocate of change and are interested in street side settlement operations or technology with MQ, SWIFT, and FIX interfaces then our platform may be the gateway to the future for you.

Paxos uses a mix of open source and commercial technologies to build our products, such as: Kotlin, React.js/TypeScript, Kubernetes, Terraform, Hashicorp Vault, and Postgres. We connect to financial institutions using technologies such as FIX, IBM MQ, and SWIFT.

  • Collaborate effectively with stakeholders across the company 
  • Constantly seek to learn new technologies and better ways to solve engineering challenges
