Summary

Proto’s mission is to accelerate the transition to a more open, equitable global economy. We believe open protocols like Bitcoin are integral to achieving that vision. The team’s first two initiatives—mining tools and a self-custody wallet, Bitkey—aim to decentralize access for builders, increase network resiliency, and make everyday use of bitcoin safe and easy. 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 bitkey.build and mining.build.

The Proto Mining software team is a newly formed team responsible for prototyping, designing, and delivering software applications to support Block’s state-of-the-art custom Bitcoin mining chip. We work closely with the ASIC and Electrical Engineering teams to redefine what Bitcoin mining looks like.

As the team is small, the candidate will be responsible for all aspects of software development, which includes building, testing, and deploying on both bare metal embedded and Linux environments.

We are a small, fast-moving, dynamic team with an abundance of growth and opportunities to make an impact!
