👨‍💻 About the Role

As a Solidity Engineer for Safe{Wallet}, you will help us design and deploy our next generation of smart contracts. Specifically, you will work closely with product and engineering teams inside the Safe{Wallet} team to build smart contract modules that extend the Safe core contracts. This includes optimization of existing extensions as well as owning audit processes. The goal is to create production-ready implementations of account abstraction features within Safe{Wallet} which can also serve as reference implementation for other projects building on Safe. Security is critical, so a strong attention to detail is a must.
