Smart Contract Engineer
About the Role
You will act as a senior contributor building core on-chain financial systems. You will design, implement, and maintain secure, scalable, and composable Solidity smart contracts, shape protocol architecture, and ensure high standards of security, reliability, and performance. You will build comprehensive tests, debug complex on-chain systems using traces and simulations, prepare audit-ready contracts, and manage deployments and lifecycle across multiple networks. You will collaborate with product and backend engineers to refine requirements, contribute specifications and documentation, and deliver end-to-end contract development work streams including core protocol components, upgrades, and high-risk financial logic.
