Job Description

The purpose of the Proto team is to accelerate the world’s transition to a more open economy by making products that increase access and independence for everyone. The first two initiatives we’ve identified that represent the biggest impact to this purpose are in the Bitcoin space with bitcoin mining and Bitkey, a self custody bitcoin wallet. While we’re starting there, we don’t believe the need for tools to increase one’s independence is limited to bitcoin or the financial space. One principle across everything we do in Proto is open development – show and tell. We develop products in the open, you can read more about them at and
