Job Description
The Smart Contract/Solidity Engineer will be responsible for designing and developing institutional-grade RWA protocols, implementing core modules such as asset tokenization, custody, cross-chain bridging, and rule engines. Key tasks include building permission management systems to support multi-role hierarchical control, optimizing cross-chain asset interactions by developing deposit/minting/burning logic, and handling asset rollback and refund mechanisms in extreme scenarios. The role also involves enhancing contract security to prevent reentrancy attacks, DoS risks, and permission vulnerabilities while implementing upgradeable proxy contract architectures for version management. Additionally, the engineer will integrate compliance and risk control features by developing rule engines that bind KYC/AML modules and execute institutional-grade compliance checks like transfer limits and address whitelisting.
Key Responsibilities
- Design and develop institutional RWA protocols with asset tokenization capabilities
- Implement cross-chain bridging solutions and rule engine core modules
- Build multi-layered permission management systems for role-based access
- Develop robust cross-chain asset interaction logic with fail-safe mechanisms
- Enhance contract security against common vulnerabilities (reentrancy, DoS, etc.)
- Implement upgradeable proxy contract architectures with version control
- Integrate compliance features including KYC/AML and transaction monitoring
Job Requirements
- 5+ years of Solidity development experience with OpenZeppelin library expertise
- Deep understanding of proxy contract patterns and upgrade processes
- Proficiency in cross-chain protocol development (LayerZero, Wormhole, etc.)
- Comprehensive knowledge of smart contract vulnerabilities and mitigation
- Experience fixing audit report issues (N4/N14/N19/N23 permission vulnerabilities)
- Familiarity with RWA business logic (bond tokenization, compliance requirements)
- Hands-on experience with deflationary tokens, asset custody, and wallet proxies
Preferred Qualifications
- Experience addressing vulnerabilities in SlowMist/Ackee audit reports
- Knowledge of ERC1363 (payable tokens) implementation in wallet contracts
- Understanding of institutional RWA compliance frameworks (legal entity binding, on-chain KYC)
Benefits
- Annual bonus + stock options
- Employment with licensed Hong Kong financial institution
- Annual health check-ups
- Weekends off
