Protocol Engineer

We are seeking for dedicated Protocol Engineers to join one of our protocol implementation teams.A protocol engineer at ChainSafe will join one of the following teams:

• Lodestar (eth2 implementation in TypeScript)
• Gossamer (Polkadot host implementation in Go)
• Forest (Filecoin implementation in Rust)
• Mina-rs (Mina implementation in Rust)
• or, a potential new team

As a protocol engineer, you will join one of the above teams (currently sized between 4-6 people) and develop and maintain the implementation of the blockchain protocol, often referred to as a node or a blockchain client. You will be tasked with implementing new features, occasionally from a technical specification or a reference implementation; maintaining existing features; and ensuring the implementation stays compatible with the current specification of the protocol, and updating the code when upgrades are made to the network. Every implementation is open-source. The position is full-time and remote-friendly.

As a protocol engineer, you have a desire to implement and deploy novel protocols that have never been implemented before in that language, you have a passion for open-source software and understanding that you will be maintaining code that will be widely used on a decentralized network, you are able to clearly communicate and document your thoughts, and you have a desire to contribute to the space.

Responsibilities

• Read and understand a protocol specification and be able to break it into issues and turn it into code
• Design and implement new features for the client
• Refactor and improve existing features in the client
• Ensure the client says compatible with the other client implementations
• Collaborate with and assist team members on their issues
• Collaborate with other protocol implementation teams to share knowledge on the protocol, whether it be high-level protocol details or technical details that are common to every client
• Communicate effectively with the team and document your code and the client as a whole

Qualifications

Required skills and experience

• Proficiency in Rust, Go, or TypeScript
• Knowledge of system design in one of the above languages
• Be able to proactively dive into novel territory and share knowledge on what you've learned

Nice to have

• Experience with blockchain protocols, whether it be usage of a blockchain API, knowledge of how a blockchain operates, or any other experience
• Experience with distributed systems, peer-to-peer systems, network programming, and cryptography
• Experience writing software from a technical specification or a reference implementation
• Experience maintaining a large codebase with many components and keeping it well-designed, future-proofed, and modular
• Experience with documenting a large codebase, both for internal and user-facing components
• Familiarity with open-source software principles
