About the Char Network

Char Network is a proof-of-stake application coordination protocol built on Bitcoin. By anchoring data into Bitcoin through cryptographic proofs and economic guarantees, Char will power the next generation of Bitcoin layer twos.

Char Network is led by Bitcoin developer Jeremy Rubin and built by a small, sharp, and adventurous crew pushing the limits of what Bitcoin can be. We're engineers who thrive on hard problems and bold ideas. Our work blends deep protocol expertise with a hacker's creativity to unlock new capabilities for Bitcoin at scale.

We keep things collaborative, fast-moving, and fun—where every contribution counts and every voice matters. Joining Char Network means working at the frontier of Bitcoin R&D and infrastructure, where the code you write and the algorithms you create will shape the future of the ecosystem.

About The Role

"A wizard is never late... Nor is he early. He arrives precisely when he means to"

If you're reading this, you probably know if you are a Bitcoin Wizard or not. You've been living and breathing Bitcoin for years. Maybe you're a Core Contributor, maybe not. Perhaps we're already on a first-name basis. If so, hope you've been well!

We're looking to collaborate with you to help push the boundaries of what Bitcoin can do. You'll be working on protocol design, low-level systems engineering, and cryptography to make Char the foundation for the next generation of Bitcoin layer twos.
