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.
