Char Network
About 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 are engineers who thrive on hard problems and bold ideas, blending 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 We’re looking for a Distributed Systems Scientist to help us invent, formalize, and implement the Char Network Byzantine Fault Tolerant Consensus System. This role sits at the intersection of research and engineering: you’ll explore hard problems in consensus, coordination, and adversarial environments—and then help our engineering team turn your ideas into hardened software.
Responsibilities
Protocol Research & Design
Develop novel algorithms for consensus.
Formalize system models, assumptions, and adversarial scenarios.
Analyze trade‑offs in liveness, safety, and performance.
Implementation & Prototyping
Translate research insights into robust, efficient code (C++/Rust).
Build simulations, benchmarks, and proofs‑of‑concept to validate new designs.
Validation & Security
Design and run experiments to stress‑test distributed protocols under adversarial conditions.
Use formal methods, fuzzing, and model checking where applicable.
Collaborate on security reviews and audits of new protocol components.
Community & Collaboration
Engage with Bitcoin Core developers, academic researchers, and the distributed systems community.
Author technical documentation, papers, or BIP‑style proposals.
Contribute to open discussions on protocol governance and deployment.
Requirements Must‑Haves
Advanced understanding of distributed systems theory (consensus protocols, Byzantine fault tolerance, CRDTs, etc.).
Strong programming skills in Rust or C++ (or equivalent systems languages).
Experience designing and/or analyzing adversarial distributed protocols.
Familiarity with cryptographic primitives used in consensus and blockchain systems.
Ability to move between theory and practice: formal reasoning and implementation.
Nice‑to‑Haves
PhD or equivalent research experience in distributed systems, cryptography, or related field.
Prior contributions to Bitcoin, Ethereum, or other consensus‑critical software.
Experience with formal verification, model checking, or advanced testing frameworks.
Published papers, technical reports, or BIPs.
Strong open‑source collaboration background.
