Blockchain Engineer, Consensus

ParallelChain Lab is the maintainer of HotStuff-rs, an open-source Rust Programming Language library for Byzantine Fault Tolerant State Machine Replication licensed under Apache 2.0. We are seeking blockchain engineers focused on the HotStuff-rs project.

What You Will Do:

• Implement highly-desired new features for HotStuff-rs (e.g. pluggable cryptographic hash function and digital signatures)
• Raise issues on GitHub to report bugs and suggest possible enhancements to the library, as well as contribute to the discussion around issues raised by other developers
• Read cutting-edge papers in systems research, algorithms, and cryptography, extracting insights about how HotStuff-rs could further evolve and improve
• Write technical documentation and tutorials about HotStuff-rs
• Work with other teams in ParallelChain Lab to together integrate the library into the novel solutions they are working on

The Must-Have Qualifications:

• Bachelor’s degree in Computer Science, or equivalent knowledge
• Strong skills in a systems programming language (e.g. Rust, C++), or functional programming language (e.g. Haskell, OCaml)
• Solid competency in discrete mathematics, algorithm design and analysis, networking, and applied cryptography
• Strong skills related to open-source software engineering, including testing, GitHub, and CI/CD

Bonus Points If You Possess:

• Some experience writing Rust software
• Some knowledge of consensus algorithms, (e.g. Paxos, Raft, PBFT, or HotStuff itself)
• Experience contributing to an R&D-heavy project
