Job Description

Bitkey sits within the Proto organization. Proto's purpose 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.
