Senior Smart Contract Engineer at Circle (circle.com)

This role is for a seasoned developer who can comfortably write production-grade code in both Solidity for EVM chains and Rust for Solana. You should have a deep understanding of on-chain security, gas optimization, and testing frameworks like Foundry or Anchor. **What makes it worth a look...** You will be building the core protocols for USDC and the global "Economic OS" at a major player in the stablecoin space. The position offers a remote-first culture in Taiwan with a focus on high-assurance code and cross-chain innovation. **You might be a good fit if you...** * Have shipped complex smart contracts that managed significant value or survived public audits. * Can switch between Solidity and Rust/Anchor without needing a manual. * Prioritize security and threat modeling over simply getting a feature to work. * Are familiar with EIP standards and the nuances of decentralized infrastructure.
