Back End Developer (nodes.js)

We’re looking for a talented 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.


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.

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
A strong interest in blockchain and cryptocurrencies (are you hodling?)
