What you’ll be working on

We’re a small team with a big mission and we’re looking for our Founding Cryptographic Software Engineer

You’ll work directly alongside the CEO and Chief Data Scientist with the support of an all-star team of A-list and highly active advisors
You’ll start by doing, rolling your sleeves up, and cranking out code
As we grow, you’ll help to build our technical team and collaborate with key stakeholders on the processes and frameworks that will allow the company to run both joyfully and efficiently

In this role, you will have the opportunity to:

  • Work in an innovative environment – have a real impact on features and products
