Independently responsible for the design, development, testing, and security optimization of core smart contract modules (including but not limited to DEX, Vault, DAO, Staking, cross-chain communication, etc.).

Closely collaborate with the audit team to complete code audit remediation, risk assessments, and the drafting of security documentation.

Participate in product architecture design and technical decision-making, providing optimization recommendations for contract economic models and system architecture.

Rapidly implement and validate new features based on business requirements (Launchpad, Bonding Curve, Social NFT, yield aggregation, etc.).

Develop comprehensive test scripts (Foundry / Hardhat) and deployment scripts to ensure stable contract deployment.

Continuously track design concepts and best practices of mainstream protocols (Uniswap, Aave, Pendle, Curve, LayerZero, EigenLayer, etc.).

Qualifications:

At least 3 years of smart contract development experience, or involvement in at least three mainnet projects (including DeFi, NFT, GameFi, RWA, etc.).

Proficient in Solidity, familiar with EVM execution mechanisms, storage layouts, gas optimization, and proxy upgrade patterns (UUPS / Transparent).

Skilled in using tools such as Hardhat, Foundry, OpenZeppelin, ethers.js, and The Graph.

Strong understanding of various DeFi mechanisms (AMM, LP, Staking, Vault, lending, yield aggregation, governance voting, tokenomics).

Proven audit collaboration experience: able to interpret audit reports and independently remediate high- and medium-severity vulnerabilities.

Familiar with common security vulnerabilities and mitigation strategies (reentrancy, access control, oracle manipulation, integer overflow, flash loan attacks, etc.).

Strong results orientation and an entrepreneurial mindset, capable of driving tasks forward in uncertain environments.

Highly self-driven, resilient under pressure, with excellent remote collaboration and communication skills.

Bonus Points:

Familiarity with Rust / Anchor (Solana) or Move (Sui/Aptos);

Hackathon awards, auditing experience, or open-source project contributions;

Experience with cross-chain communication (LayerZero / CCIP / Wormhole) and ZK ecosystems;

Core R&D experience in large Internet or leading Web3 companies (e.g., Binance, OKX, Bybit, Bitget, Coinbase, Scroll, LayerZero, etc.) preferred.
