Libraries and Tooling Team

Join the team responsible for creating battle-tested libraries of smart contracts for Ethereum and other blockchains. 

What you'll be doing

As a Open Source Developer, you will join our team that works on open source libraries for Rust smart contracts, for use on multiple blockchain platforms such as Arbitrum Stylus, Solana, or Cosmos. This library will offer similar capabilities to those found in the widely adopted OpenZeppelin Contracts library. We are looking for developers who have strength in Rust development and are familiar with smart contracts written in Rust, Solidity, or other smart contract programming languages.

In this role, you will play an essential part in designing and implementing new library modules, communicating with smart contract developers and blockchain network community members to gather feedback, and working collaboratively with other members of the development team to make sure our open source library meets developer needs and expectations. You will be responsible for library coding, testing, documentation, and security. You may also participate in open source tools development to assist developers using our library.

You have

• 3+ years of experience in software development.
  
• 2 years of experience developing Smart Contracts (Solidity or other languages)
• 2+ years of Rust programming experience.
• Good understanding of security concerns in the Ethereum ecosystem.
• Interested in or knowledgeable about Ethereum L2s.
• Prior experience working remotely: strong personal organizational skills, a love for self-time management, and ability to work collaboratively with a team.
• Advanced English communication skills — all of our internal and external communication is in English.

Nice to have

• Experience contributing to open source projects.
• Experience writing smart Contracts in Rust (Cairo, Solana, etc)
• Understanding of cryptography, elliptic curves and some experience developing cryptography libraries
