About the Role
You will own smart-wallet architecture, including account models, signing, sessions, and gas abstraction. You will design ERC-4337 and EIP-7702 flows, secure dApp-facing wallet interfaces, custody and recovery systems, and paymaster strategy. You will lead technical decisions, mitigate wallet risks, set engineering standards, and resolve complex production issues.
