Senior Backend Developer

KNØX is a custodian for cryptocurrencies. We're looking for a talented backend programmer to develop secure and robust components for our core activities: key management, payment processing, and risk transfer.

The tools and systems you build will be part of our core custody infrastructure. You must be able to design and implement software securely and concisely.

To excel at KNØX you must demonstrate exceptional performance across multiple paradigms. You're likely someone who has an eye for details which gives rise to a deep interest in distributed systems, writing bug-free code, and the practice of engineering software.

If you are interested in leading projects from conception to deployment and exploring a problem space without established solutions, we'd love to talk.
