Description

My client is a leading Web3 and Decentralized Finance (DeFi) company and looking for a Senior Smart Contract Engineer (Solidity/Rust/Move) roles. Core Responsibilities Protocol Architecture & Deployment: Architect and implement core on-chain protocols for a Decentralized Exchange (DEX), including capital vaults, clearinghouses, and settlement engines. On-Chain Transaction Logic: Develop the underlying logic for clearing and settlement processes, ensuring high-fidelity integration with off-chain high-performance matching engines. Oracle System Integration: Design and maintain robust Oracle contract frameworks to support real-time price feeds, data validation, and asset valuation. Security & Audit Management: Lead smart contract security hardening initiatives, collaborate with external auditors to rectify vulnerabilities, and oversee mainnet deployments. End-to-End Synergy: Partner with backend and QA teams to bridge the gap between off-chain trade commands and on-chain fund movements for seamless execution. Candidate Requirements Academic Background: Degree in Computer Science, Software Engineering, Cryptography, or a related technical field. Solidity Mastery: 3+ years of professional Solidity development with deep expertise in EVM mechanics, Gas optimization techniques, and ERC standards. DeFi Domain Expertise: 2+ years of specialized experience in DEX clearing and settlement workflows, including sophisticated Oracle integration. Multi-Chain Proficiency: Proficient in Rust or Move programming, with the ability to lead contract module development across diverse blockchain ecosystems. Ecosystem Knowledge: Strong understanding of the architectural paradigms of high-performance chains such as Solana or Sui. Preferred Qualifications Experience developing advanced vault standards (e.g., ERC-4626, ERC-7540, or ERC-7575) and complex accounting logic. Familiarity with advanced security methodologies, including Fuzzing or Formal Verification. Proven track record of successful smart contract audits or hands-on experience in incident response and protocol hardening.

Responsibilities

The role involves architecting and implementing core on-chain protocols for a Decentralized Exchange (DEX), including developing the underlying logic for clearing and settlement processes. Responsibilities also cover designing Oracle contract frameworks, leading security hardening, and ensuring synergy between off-chain commands and on-chain fund movements.
