Unbanked is a global fintech platform built on blockchain. Unbanked’s platform connects traditional enterprise, fintech, banking, systems with blockchain infrastructure giving real world utility to digital assets. Our products enable instant remittance and the transfer of value on blockchain rails in a compliant and regulated environment.

We’re looking for a talented Back End developer with a range of skills to help us build the future of crypto payments. Our core consumer facing product, BlockCard, is a crypto debit card available in the US. We have built a white-label platform for easily onboarding partners to run their own cryptocurrency debit card programs using our technology. Existing partners include the likes of Litecoin and Paxful.



Ultimately, you’ll be responsible for helping our team build and maintain BlockCard. You’ll get the chance to work across a variety of technologies, but our backend is primarily written in Node.js.

We expect you to be able to take end-to-end ownership of product features assigned to you. You should be well versed in debugging and troubleshooting user reported errors as well as providing fixes. Aside from developing new features, you will be responsible for helping improve the underlying application architecture in terms of performance, caching, security, uptime, and error handling. You should be comfortable operating under a CI/CD environment.

  • A background in CS: algorithms, data structures, system design, and database design
  • A history of unit testing or behavior driven development experience
